Bitmain will be releasing S15 and T15 on 8/11/2018

[mettalmag]

It seems they skipped the S11 and T11 and switched to S15/T15. They will be on 7nm chips.
est. price and shipping date unknown atm.
Release date 8/11

imo they will flood the market as they usually do, diff will sky rocket and yea RIP S9

not sure about that info but hashrate seems a bit too high no?

Considering 14nm chips are 13.5th at 12xx watts I’d expect around 26-27th range for the same wattage. That’s a big IF on them solving all the issues with the 7nm chips.

I'm betting on that but a bit lower, just a bit

[minefarmbuy]

Spec wise we're probably looking at 28-30th/s at 1500ish draw. Looking at market could see a price range from $1.2k-2.2k. Most likely on the low end to compete with the T25.

Also the added tariff is 25%, for a total of 27.6% duty to the US.

But they did claim under 50 watts a th.

[minefarmbuy]

Picture also hints at integrated psu and dual fans one side. So quad fan?

We should be able to rule out their need to use the APW7 for this.

Thinking 35- 40th/s at 2500w perhaps? (high end)

[Mousem40]

'Wu said tests have shown that the chip can achieve an energy/hash ratio of 42J/TH'

The 13.5 S9 was using 0.098W/GH, meaning 98J/TH. This is potentially 2.3 X more efficient. So it's capable of around 31TH using the APW3++ at around 1400W?

But they won't max it out to start with, they'd want to bring out newer, improved versions later on, so perhaps 28TH @ 1,350W?

It appears to be lessor in depth also, they have probably realized that shorter hash boards will have better cooling performance.

[philipma1957]

The best a s7 with lots of mods was around 0.22 or 220 watts a th

The s9j can do about 88 watts a th

On a chip rated about 0.068 watt a th.

Bitfury 100 watt a th  gear

Can go as low as .06 watts a  th.

So a .042 watt chip

Is going to be more like 55 watts maybe 60 watts a th.

I just wish two things a manual speed not auto tune.

As I prefer slight underclock.

And if it goes on sale on nov 8 I hope it ships quickly.

If it is 1200 I am looking at 1600 after shipping and tax.

Not sure it is worth 1600 unless it comes really fast and does 55 watts not 65 watts

[CryptoCrane]

Yeah, these additional 25% tariffs are definitely killing us miners here in the US. Quite frustrating.

[sidehack]

As an electronics builder in a family of beef and soybean farmers, I get to see the tariff double-whammy up close. China's retaliatory tariffs on us are for products they can buy from at least 20 other countries. But our best tariffs on China are for products the entire planet (led by us) has, over the last 30 years, tacitly handed complete control of to them without any concerns whatsoever. Has China's export business even noticed a dip?

I'm pretty sure they will be more than 1200 stock + shipping and taxes in some cases

[QuintLeo]

It will take a while for the 7/10nm generation miner makers to make enough miners to push the difficulty up to the point the S9 becomes unprofitable if you have VERY cheap electric - but that point will get reached eventually.

I doubt the S15/T15 can get 34TH at 1500W. GMO has their 7nm chips out and their Miner B3 unit is 81W per T. A lot of the power efficiency and how well it performs comes down to chip design. We know that Bitmain is bleeding money and they lost most of their best engineers. If their ASIC really was as awesome as they claim it is, they would have released some real numbers on their "teaser" release. So the only thing really they could hype about is the 7nm technology. If their chips really did 45W per T, they would have bragged about it already. Just my 2 cents.

[minefarmbuy]

In a few hours we'll know more. Just wondering how much.

The whatsminer m10 does 34th at about 2400watts.  I have two of them. And they use a 16nm chip.

So I get around 68-70 watts a th with them.

I think we will get 55-62 watts th with this gear.

The real concern is how fast do they ship it.

S15:
850W wall means 790W DC -> 750W boards -> 710W chips for 0.042J/GH at the chip.
1600W wall means 1470W DC -> 1390W boards -> 1290W chips for 0.046J/GH at the chip

T15:
1200W wall means 1100W DC -> 1030W boards -> 980W chips for .049J/GH at the chip
1540W wall means 1415W DC -> 1330W boards -> 1250W chips for 0.054J/GH at the chip

I buy the T15 numbers, but if the S15 numbers are correct it's a bit of a feat. Not so impressive considering it took them 2.5 years to just beat what Bitfury and M10 are doing with 16nm. I'm mostly impressed that there'd be a sub-KW option.

Maybe not.

[sidehack]

Edited, sorry for the mislabeling. I was paying too much attention to all the other numbers. A sub-KW sub-$k miner would be pretty nice with anywhere near that efficiency.

[Biodom]

Buying or not buying might depend on the price and other characteristics.
For example: is lower wattage a different machine (like mini) or is it a different set of frequency.
They actually implemented it (two settings) in some other machines as balanced vs turbo settings.

BTW, is it worth it to do passport/DL KYC with Bitmain and risk losing your creds somewhere in china?
Honestly, i don't get it why we have to do it since they already have our names and addresses?

44 watts a th is head and shoulders better then the m10 which is about 68 to 70 watts a th.

But they did claim under 50 watts a th.

Same ballpark as Bitfury's "Clarke" chip.
Bitmain does have a history of getting higher performance out of a node than most of the competition (though Bitfury is usually in the same ballpark).

Innosilicon in particular tends to be lower performance on a given node than Bitmain manages (there are persistant rumors that the Innosilicon A3 was never released because it was no better to worse performance than the chip that Bitmain used in the S7 on an older node).

[Thetaj]

Looks like the official spec is 34th/1600w

Lets see if its true but from my supplier he says this +/- 10%

So they have updates the sales option on the chinese site.

I checked it out and translated just to get there. Here are their numbers

S15

28 TH/S +/-2%   @ 1596W  +/- 7%     states 50 J/TH

Efficiency Mode - I think can't confirm as I can only read the numbers but it still looks like there is only 1 machine option

17  TH/S +/- 2%    @ 850W +/- 7%      states 57 J/TH

*Updating *

T15

23 TH/S  +/-2%  @  1541W  +/- 7%      States 67 J/TH

Efficiency Mode - I think can't confirm as I can only read the numbers but it still looks like there is only 1 machine option

20 TH/S  +/- 2%  @  1200W  +/- 7%     States 60 J/TH

Both include the PSU and have max order quantities 2 for the S and 5 for the T

I belive they are also stating delivery between December 1 - 10. Might just be for China. There may be a price in there as well, but the format it translated to looks funky so I'll leave that out.

[mettalmag]

my source was right

[philipma1957]

So a dec 1 to dec 12 ship date.

That is not too bad.

And a 50 watt per th

That is good.

[mettalmag]

I wonder how long they have been mining with this devices, I also know about S11 and T11 which never exposed to public and I've seen the prototypes 2-3 month ago.
Dec shipping isn't that bad and now I'm guessing what will happen.
Oh and as I know first batch quantity will be limited to max

[sidehack]

Do I see a control line going into the power supply? I've been wondering for a while, what with all these miners now coming with power supplies built in, if they might be dropping the board-level string regulator and tightening control on the mains supply instead. That removes any opportunity for board-level tuning, as now the entire miner has to ride the required voltage for the weakest single chip, and it also removes the option to ever replace your power supply with something other than their specific build (so you're over a barrel, warranty-wise). If they're binning chips pretty specifically imbalances can be minimized and you end up with around a 3-6% efficiency gain and slightly reduced BOM. That binning might be why they're rolling out both a low-spec and high-spec model at the same time.
Looks like they may also be slacking on the density a bit, or at least starting to shorten the air path which keeps the rearmost chips from getting overcooked. That's a good sign, and a lesson that should have been learned from Spondoolies rack gear in 2014.

Yeah the S model numbers look awesome. They are definitely trying to regain the king of the mountain spot with efficiency. The price will be interesting. Depending on what rumors to believe are they going to try and grab as much Bcash/Fiat as possible quickly. Do they look to maximize profit, not worry about how fast the product moves(probably not an issue with the specs).

I updated that post as well, once I saw what looked like Delivery between Dec 1 - 10. Only being 3 to 4 weeks out is better than I thought. I expected end of Dec/early Jan.

That removes any opportunity for board-level tuning, as now the entire miner has to ride the required voltage for the weakest single chip, and it also removes the option to ever replace your power supply with something other than their specific build (so you're over a barrel, warranty-wise).

This has always been my worry about buying a unit/PSU combo. Now you've given me a logical reason for that. Obviously without a closer look we don't know if that's for sure the case, but I don't have a decent option to warranty with them. So losing the unit over a dead PSU, would be a piss off.

Spec wise we're probably looking at 28-30th/s at 1500ish draw. Looking at market could see a price range from $1.2k-2.2k. Most likely on the low end to compete with the T25.

Also the added tariff is 25%, for a total of 27.6% duty to the US.

I guess I was pretty close to.

Pricing looks ok.


On the cn web the t15 batch 1 sold out. Second batch is more expensive?

most of these S15 and T15 are going to be on the ebay soon.
Its a good step to the next level for Bitmain but not very profitable models and shipping is going to happen on a month from now.

I wouldn't spend crypto on it. Blokforge has them available with credit card and total is about the same you'd pay ordering from Bitmain after tariff and shipping if you're in the U.S. Pricing is better than anything else on the market and I don't see price dropping unless Innosilicon, Canaan, or another manufacturer engages in a  price war.

With tariff and shipping, Bitmain price is at least $2k ($1475 + $407 tariff + $130 shipping). Blokforge is $2200 shipped with card fees. If you have Bitmain coupons I suppose it may be better to order direct, but I'd rather support a U.S. business when difference is minimal especially when they've helped me out with free product in the past.

Unless it's a group buy pricing is static with us and we return unused funds. S15 we might be able to get US batch 1 in volume but probably not a single unit. This is were resellers like Blokforge are good. I don't think we've sourced for them yet but would be cool to collaborate with another US company especially if they're good poeple to work with like sidehack and GS have been.

guys, S15 is crap. like comeone..2k usd with all customs,shipings,etc and doin 6usd per day with free electricity and 2.5usd with 0.1per kwh..
count the ROI ffs..2000usd price and 2,5usd per day...so 800days IF all stays same (diff, hash) which do not stay,everyone know that,right. it is better to buy BTC now for 2k usd,like 0.3 or so and u save nerves, noise, electricity.

someone who has free electricity,better buy S9i 14.5TH included PSU for 400usd+customs. 2x S9j still better hash than s15 and u still save money like 2x (600-700usd) vs 2000usd.

Ebang E11++ is doing 44TH / 1900W on 10nm samsung...and cost around 2000-2500usd...

if S15 would cost 800usd, i would buy one, but in this case..of course they make quality machines (i havent had any trouble with them)

Don't forget to factor in the cost of 2 power supplies for the S9 option - and the MUCH lower efficiency that will eliminate it's profitability in the not-too-distant future.

392USD included PSU for 14,5TH S9j. yes less profitability than S15 (14,5TH vs 28TH), however i mentioned that for those people with free/cheap electricity is S9j better option as give more hash (29TH vs 28TH) and cost less (800 vs 1500). someone whi has really free electricity, can have 4x S9j for same price 58TH vs 28TH....
just sayin...for people with expensive electricity is better option to BUY BTC directly.. someone with medium electricity rate, well,the need to really think about it...

Exactly right, these S15's are overpriced by almost 40%...

[philipma1957]

Exactly right, these S15's are overpriced by almost 40%...

they work if you have high power cost and run on 50 watt setting.  

if you have 15 cent power they turn profit of $23.70 a month

if you have a m10  it loses $22.36 a month.

now that is a frozen moment in time  and for long term  it is going to change a lot.

also bch is Daily Yield: ≈0.00037295 BCH Per TH/s    so 28 th is 0.01044 bch or  $5.99 a day with a split coming very soon.

btc is Daily Yield: ≈0.00003396 BTC Per TH/s   so 28th is  0.00095088 btc or     $6.09 a day  with no split

[stompix]

At 5 cents per kw I'm getting the money back next November....
Unless:
-it brakes down till then
-I get a hike in electricity prices
-Difficulty goes up (lols on this one)

Not that keen on mining again but till now seems like the s9 would still be the better option short term if only talking about bitmain products

just buy BTC for same money... as next november u wont have same btc by mining. And if you like u can buy one S15 for 400usd that time and continue mining
i dont know,mabye i sounds sceptical, but there are better miners than S15 and i see better option to buy btc directly when the price is relative low and save your nerve, noise,etc.. however 5cents sounds good.
for last 6 months diff went up from 4T to 7T+its almost double = your profit half. and then in 12months it will be even less. so if u see today that u will mine with S15 in year 0.36 then u are mistaken. if u will mine 0.2 that wil be success. now u can buy for 2 000usd around 0.3BTC lets say.

my point is it is overpriced, it should got for 800-1000 max with psu.

for last 6 months diff went up from 4T to 7T+its almost double = your profit half. and then in 12months it will be even less. so if u see today that u will mine with S15 in year 0.36 then u are mistaken. if u will mine 0.2 that wil be success. now u can buy for 2 000usd around 0.3BTC lets say.

my point is it is overpriced, it should got for 800-1000 max with psu.

https://www.coinwarz.com/difficulty-charts/bitcoin-difficulty-chart

the diff has not risen much  since august 24th.

[Thetaj]

At this point, its better to do absolutely nothing and maintain the farm as it were. Bitmain will definitely lower the price anyways because from what I've heard, the preorders were subpar at best. Either that or Btc price goes up alot......in which case it makes more sense still to do nothing and hold your Bitcoin.........

[QuintLeo]

Exactly right, these S15's are overpriced by almost 40%...

Much higher efficiency, which has always been a good justification for a new miner model costing more per hash.
S15 will be profitable for years, the S9 will probably be a money loser at 3 cent electric by this time next year.

[minefarmbuy]

We'll there're more for sale should anyone want one.

[PeaMine]

I also feel before these even ship out, either price of bitcoin will go down or difficulty will jump up a considerable amount.  They will also have "batch 2" orders in a week or two at a much lower price to compete but with another 1-2 month shipping delay.
They did this with the S5, S7 and S9.  S4 there wasn't much competition and it was a true shortage of miners versus demand at that time so at times prices would go up and stay up.
Back when it was an actual good deal, they sold out and stayed sold out until the next batch.  I haven't seen the S15 or T15 sold out for several days now.

Edit: well, there is the bitcoin price fall.

[Steamtyme]

Hard to say what's going on with them ATM, I'm pretty sure they sold out the first day launch. Whether they call that batch1 or label things in that manner anymore.

Can't be hurting as I still see the 2 unit max per order through the site.

Well were already seeing a large price decrease whether that holds as the new normal or not is yet to be seen.

There is no new "more efficient" node anticipated to BUILD miners on for years.
Is that hard for you to understand?

In fact, there is some question how much longer semiconductor node CAN continue to progress - GMO's over-optimistic projections to the contrary.
Intel and IBM in particular have both stated that "pure silicon" has reached the end of the road - IBM's current "next gen" process design work uses a MIXED silicon/germanium die while Intel has been quite mum on their plans for anything past their current 10nm node.

The old "new miner model every 6 months" routine died when ASIC mining hardware caught up with semiconductor state-of-the-art at the 14nm node (S9 and such), and CAN'T ever return.


Just noticed something I find a bit iffy about the S15/T15.

"exposed die" design on the chips.

Does anyone remember the massive FAIL issues associated with that concept on the Athlon Thunderbird/Palomino and same timeframe Pentium 3 generation CPUs that ALSO used an exposed die?

Probably less of an issue with the "glue-on" heatsinks Bitmain uses, but still a bit iffy - and definitely NOT THE NORM that Bitmain claims in that part of their "overview."

Your plan is nice on paper, mine long time, but unfortunately right now if we assume a flat price and over 7 cents per kwh you're not going to ROI before the halving  

Of course, prices might go up but at that point just buy directly BTC.

The s15 might be efficient but it has a price tag that is dragging it down and this is not a normal industry, I doubt there is something out there where you have to plan a halving in global markets every 4 years.

With an s9 you're going to ROI faster and start making a profit faster, the s15 is indeed for the long run but it might take way too much time to make some bucks on it.

Slash the price at least 25% and yeah, it looks attractive but at its current price...nope. Just no!

[sidehack]

Don't forget how much money you'll have to put into maintenance and repairs to keep it running at spec for that whole time. Bitmain gear isn't built to last for two years.

This. As someone who has been running Bitmain gear from the beginning I can say for certain that their gear fails over time. I've had hashboards, control units, fans, etc all go bad in no time.

I think a lot of people like to forget and overlook how much maintenance and failures add to the cost of a miner. Add to that the inevitable downtime when things go wrong and you end up pushing the ROI out much, much further than what is perfect on paper. We used to have more room in the margins for these added costs. Not so much now. At least when it comes to mining BTC. Its slowly becoming a fools game that only benefits the ASIC makers.

[QuintLeo]

They tend, from what I've seen and many other reports, to have a lot more issues with "infant mortality" than death over time - like most electronic gear, especially when it's pushing a heavy load.

[DaCryptoRaccoon]

From what I hear they had issues with the chips and wafers so this is good advice unless you enjoy looking at a machine while parts are away for repair or replace.

[betajuice]

Is there a way to order a larger amount of the S15's ? From Bitmain's site, they are limiting 2 per order. Are there third party suppliers that will sell them in bulk?

I might budget to include units for possible repair. Maybe order an extra or two to swap pending your farm.

Did any of you guys get a coupon? If so for how much? Are they still transferable?

Im curious because I didn't order anything from this last batch I wouldn't know.

If the coupon was good enough I might consider a few S15 or T15 miners I guess.

Are they still grilling you for your personal info just to place an order?

Yea, reason I don't shop personally with huge companies as much as possible. Anything I need I just ask them here to get it for me. We have some buyers who pay more in shipping just so the deliveries are routed through us and not directly to them. Even a little buffer goes I a long way I suppose.

[ConnerM]

Has anyone seen any detailed specs on the S15's PSU? 127/220 is a common industrial voltage output from 3 phase service in many parts of the world, but we run our farm on US 3 Phase WYE service which gives us native 208v. It's doesn't appear that the new BitMain gear is being designed for the US market, but I'm thinking perhaps the input voltage specs may actually be a little more flexible than what's being shown.

Any who, reworking the farms supply panel or adding boosters for this gear would make it cost prohibitive, as if it isn't already.

I imagine it should work 208V, best efficiency will be on 220v from what I understand. Maybe some one more knowledgeable will chime in shortly.

[NotFuzzyWarm]

When something claims '220v input' it is implied that the standard range of 200-250v is acceptable. If not then the rating should read '220v MUST be used' with strong emphasis on that. That said, being Bitmain it still is a reasonable question to directly ask them.

[kodokbuduk]

Any review with S15? anyone has received it?

[Steamtyme]

Haven't seen anything yet. Looking back some orders from the China site should have shipped by the 10th of December.

I'm not positive on the earliest ship date outside of China, or if anyone on the forum placed an order. It would be nice to see a unit and find out if matches the advertised performance, because then this would be the most efficient hardware available. (S15)

[VRobb]

The email I got extolling the wonderfullness of the $230 coupon I received for buying the first batch said shipping will be from Dec20 to Dec31, a little later than originally promised.  The coupon is nice, however I just bought back the coin I used when I bought the miner at BTC>$6000 and therefore only paid ~$700 for the miner plus shipping.  Seems resonable...  

Edit - MFB you are correct.  Checked my original purchase confirmation and indeed it's late December.  At least I still made a killing on the BTC buyback! 

[minefarmbuy]

Dec 20th- 30 is the first "English" site batch shipping dates.

[sikke1]

No shipping from bitmain yet, bought in November.

I purchased my T15 from Amazon last Thursday. It arrived Monday.

Good job getting your hands on it a little early that way.

Can you post a screenshot of the miner status, and maybe a pic or 2 of the miner? It would be nice to see it in action and confirm they have something close to spec hitting the market.

[PassThePopcorn]

Bitmain released today Firmwares for the S15 and T15.
The T15s is newer. Since it is operating I am not going to flash this.
Anyone have any observations either model??

The S15 seems to work as advertised, however there doesn't seem to be a way to SSH into it. The dropbear daemon is there but it is set to not allow connections. Does the T15 allow for SSH?

After it got up to speed it was using 18V, but was using 20V until it started.

The S15 also seems to use cgminer and not bmminer as previous miners use.

PassthePopcorn posted some results from their miner in the Competitive hardware thread, I just haven't had the chance to update it.

So far it looks like a good buy if you've set up KYC with Bitmain. Especially if you have higher power costs as they are so far showing great options for efficiency for both of the miners.

Obviously it's a small sample but well see as more if them arrive

I am trying to get both a t15 and a s15.

Since I won’t use bitmain direct and will only pay via PayPal or Credit Card it has proven difficult to do so.

Maybe they would let me get the t15 and the s15 via cc or PayPal.

They were accepting credit cards previously. Maybe they got a lot of charge backs from batch 1? I'm still waiting on mine and disappointed that I will essentially be receiving it the same time as batch 2. No point in doing pre-orders when they drop the price and you don't receive on time.

Yeah I got the a921 on a cc.

It would be nice if they let me get the t15 via cc.

I’d review it and move it onto the solar array.

Then get a s15 review and move it onto the solar array.

I am frustrated that I do see a mention of cc but not a tab to press it.

If we ever see an asic's box we try have them picked up same day for distribution. FedEx in states and to Canada have been best rates domestically, nothing to Latin America for couple months though. I'd love to get one, the s9 at 13.5th/s is still drawing 1200w even with new firmware.

Now, let's see if this miner is solid.

[NotFuzzyWarm]

When you get it, please take a look at how power is fed to the hash boards.
I'm thinking that BM will not be having Vcore regulators on each board and instead will be controlling output of the PSU itself with the chip strings fed directly from the rails. Reason: Losing the additional board level regulators gains several % efficiency

[hacky]

... I wonder if that new fan placement is better than the usual tunnel? And what are RPMs for the two fans?

I have my S15 running for 1 day. The two fans for the hashboards are more silent than the little fans in the power supply (APW8). The two fans runs between 3500-3600 and 5000-5100 rpm (21°C ambient). It seems there are two speeds for the fans at full power (1590-1600 W for 28.4 TH/s), maybe more speeds if the ambient temp rises, will see

No problem for the moment after 30 hours of mining. Slush pool returns a day average of 28.5 Th/s. That's OK with the specs.

I received my S15 yesterday. I have it in regular mode currently and it's been averaging 29 TH/s on Slush. Not sure on power draw as I have no meter. The fans seem a little crazy. They will be more quiet than anything else on my rack and then go into full blast like the unit has been rebooted and be louder than anything else. Goes quiet and loud over and over. I will have to double check, but both fans seemed to be sucking air in, not exhausting, similar to Z9 units. My ambient air temp with all my other equipment running is around 50* F.

This will surely help to avoid hot spot and better temp reading.
This give me a good felling about improved reliability.

Finally a powerful 7nm miner with better design then packaging 2Kwatt+ in a single tube.

Thanks for sharing

[sarcheer]

it is an okay price good luck with it.

Thanks! This is the first time I've bought a miner brand new from Bitmain, hoping I don't get screwed by their low-reliability. Also hoping that the limited batching will result in higher than normal reliability rates for these new machines. Plus I got to finance through Paypal so that helps haha

[HagssFIN]

New batch for S15 is listed on BM site. 27th at 1600w, 16th at 850 LPM. Thought it might be a new version but specs are essentially the same unless I missed something,

https://shop.bitmain.com/product/detail?pid=00020181210184613385gc3S2eKL0674

I bought one S15 from this batch to test it out,
not sure if I will have a place for it in long term.  

Maybe my friend who lives in a student apartment can help me out,
if it is not too loud in the low power mode.

But what I've seen in videos so far,
it seems that the psu can be quite loud.

The only issues I've had with bitmain where asics bought second hand. Everything I've ordered direct has had zero issues personally but that's been only two units. I don't think we've had any service requests since we launched on any units that have been delivered regardless of make. brb, knocking on wood.

The early s9s had issues  in 2016  but the l3+ the newer s9 the s9i the s9j have run well for me.

[minefarmbuy]

Yea, confirmed we have an immaculate track record. 0 warranty claims on all asics. Not that we expect that to last but kind of nice stat to share since opening our asic sourcing back in April or May.

It is louder than anything you have had   the psu fans have high pitch noise. They are crazy rpm small fans. The big fans really move some air but they are loud. So loud cant live with it or neighbour will complain.

Possibly a couple of loose heat sinks? A couple of heat sinks out of alignment, disturbing airflow and creating dead zones of air?

Basically, have you tried looking closely at your boards to see if there is anything visibly amiss?

Switch to low mode.

Also before you switch.

You may have poorly glued/attached heat sinks.

I have had lots of s9s. With hot boards.
So a hot board is not unusual.
Seeing all four boards on all four units
On low and high power will help us to analyze what is wrong.

[minefarmbuy]

Looks like middle boards are hot. Dead zone for cooling with two fans possibly?

I don't have one but I imagine the fans blow in? If so, maybe the middle needs a small case fan pulling at the back for short term till you dial in the machine for your racks/farm.

Start a support section thread if needed.

This is 2 of my 4 mashine.
I am used to s9i at pretty hi temperature 85-90 in summer but the S15 is shutting down at 96.Temp. room is 20 degrees. It migth be to smal innflow of fresh air in the room as i suspsect low pressure. The fans are blowing in.

[sarcheer]

Well that eBay seller was legit, just got delivered tonight. Had I waited two days I would have saved $150 as the seller lowered his prices lol. Will post unpacking pics and my review in the coming days as work permits.

So some notes from my Antminer T15 setup experience:

Took approximately 6-10 minutes on average for my T15 to start up and complete tuning/begin hashing.

I initially had a network error, which turns out to be because the T15 does not accept pool addresses with the "stratum+tcp://" prefix. You simply specify the stratum address, e.g. stratum.slushpool.com:3333

Currently consuming ~7.5 amps at 200V, so around 1500W at normal mode, hashing at 23.5 TH/s.

This T15 came with the 12/18/2018 Firmware installed which may be why the start up sequence was quicker, or because its running in a 75ºF environment.

Also, my T15 HAS the top cover, so no exposed rails here.

That's a bad sign. I have really high ambient temps in the summer. Lots and lots of flow, but I take 90+degree temps in the summer and exhaust 100+degree heat at times. This makes me think I have no hope if I buy these and try to run them through this summer. AC is not an option.

Great share sarcheer, more flex with the T15, S15 if you have active cooling or less than moderate temps.

Based on information available S15 and T15 in eco mode are very close in spec.

[fanatic26_]

I received my first T15 this week finally. It has been up for about 2 days now. Here is how the setup went and my findings.

Out of the box the machine would not pick up an IP, had to do the IP report reset right out of the box but it immediately came up after that.

Initial test cycle took a long time, the machine did not start hashing until about 25 minutes after power up.

Normal mode results:

23.1TH @ 1560w at the plug.

LPM results:

20.9TH @ 1260w at the plug.

Other than the somewhat long boot times I am seeing (switching to LPM took another 15 minutes before it would hash) everything is running great.

Factory LPM specs are 21th max at 1260 and they NAILED IT. I couldnt be any closer to the advertised specs.

With all the other miners ive been testing having extremely loud 140mm fans its kind of nice to have a new miner with 120mm fans. Also helps keep my fan inventory useful going forward since I have hundreds of 120mm fans.

[NotFuzzyWarm]

^^ Good to hear.
Now the question will become how many weeks/months the miners run before we start seeing issues

Here is 6days uptime numbers. Antminer T15.
My firmware is: Tue Dec 18 11:04:09 CST 2018. This unit is directly from Bitmain.

[HagssFIN]

Dang, I knew I should had wait a bit.

I paid 1.2k USD for the S15 (27Ths  Jan. 11-->)
and now they dropped the same batch price to 1k USD.

Fuck.

[VRobb]

Hmmm, a grand, minus $250 coupon I got for buying first batch, for another S15 is tempting...
May just have to pull the trigger again!  

EDIT - Ah Steamtyme, my mistake, only a $230 coupon.  Still tempting!

[Steamtyme]

Vrobb I'm sure they're sticky on this, the largest coupon you can use for this batch of s15 is a 240$.

I only know because at that price I've been on the hunt for real, and cheap coupons.

Dang, I knew I should had wait a bit.

Damn, I hate when that happens. Email them and maybe they'll throw you a bone, probably in coupon form.

I have been doing this for a few years now, and bitmain reliability is on par or better than any company I have worked with outside of Canaan, whose miners are never competitive anyway.

[JonnyRocket]

I had a lot of problems with the network error initially. But figured out I needed to follow the static IP setup to accept a new pool. I think it's a great machine so far. 28.5ths running full power. Over 18 in economode.

[minefarmbuy]

Decent Bitmain price drop ftw.

[ruber1]

T15 issues. When switching pools I keep getting Socket Connect Failed. It takes several re-boots (quite a few sometimes) and finally connects. Annoying. Now, after less than a week, I lost a chain. So now hash is under 15TH.

[philipma1957]

So much like the early s9s there are problems.

So far 1 t15 and 2 s15 based on the threads.

Batches 1 to 6 on the s9s had trouble .

Can you. try. A different firmware?

[HagssFIN]

And it looks like they changed the S15 price back to 1.2k USD.  

No coupon was sent to me.

[VRobb]

Crap, makes the coupon moot doesn't it...  

Got 'til the end of the month before it expires, guess I'll keep an eye on price and make a move if it dips again.

T15 issues. When switching pools I keep getting Socket Connect Failed.

For the 10 trillionth time, Socket Connect Failed IS NOT AN ERROR.

Literally all it means is cgminer is not running.

I have noticed when changing pool information on the T15 it can take another 15-20 minutes before it starts hashing again.....how long did you wait before deciding it wasnt working?

Yeah this also happens on other machine from other companies they are all running cgminer. Even 30 minutes before it connects can happen.

Some tips if it happens a lot

use good ETH cables
Make sure your switch works.
Long ETH cable runs can make it worse.

Avoid WiFi

Seems they are selling 27 TH/s and 28 TH/s batches at different prices now. My scoring hashrate has been averaging 28-30 TH/s on Slush and sometimes spikes at 32 TH/s. No problems since turning it on.

[ConnerM]

What input voltage are you guys running these at? The 8 S15 28Th units we've been running on our rack @ 208v since Monday are all functioning perfectly. Two units that arrived yesterday that we setup at a different location on 240v ran fine initially but both failed within 12 hours. PSU dead, no power. The card included with the units shows a rated voltage range of 200-240v.

[Pizzi_h]

Anyone gotten to Overclock these babies?

I’m running my T15 at 200v since Tuesday without issue. How long have you waited between trying to get it running again? The APW5’s I have, when they trip into protection mode, can take 15 minutes of being unplugged before they’ll respond to power input again. I wonder, what are the stats on the APW8?

I was thinking that too. Did try to re-power the units a couple times over the course of a few hours, but no luck. One unit was in my basement, about 60 degrees ambient and only ran for about 45 minutes. The psu on that unit was quite hot to the touch just after it lost power. The other unit was in my garage, about 35 degrees ambient. That unit ran for 11 hours before it lost power, again, the PSU was quite hot to the touch. I put a meter on both the outlets and they tested 240v. I will take both S15's back into the office Monday and put them on the rack at 208v and see if they power back up, or if something inside the PSU is actually blown. I would like to open them up and do some power troubleshooting but I don't want to void the warranty in case they need to go back. Bitmain doesn't seem to be offering any spare parts for these yet. I don't know if my experience is typical but I wanted to throw out a word of caution if anyone else is operating these at the high end of their voltage rating.

[philipma1957]

did you choose full speed or low speed?

seems to me you choose full speed.

I wonder if 240 volts and low speed is safe
and 240 volts and high speed is not safe

also  does your 240 volt setup run  hot say 243 volts to 245 volts.

My home  can be 238 to 246 volts.

It could be  you drifted past 240 to 243-246 and on high speed they power down.

I wonder if they would have been fine on low speed.

So this now brings us to 5 issues for the s15's in this thread.

As of today  I think no one has said the m10 has had a fail.

I mention this  because  the t15  s15 m10 are the three best units for mining as of now.

It will be interesting to see if the t15 and s15 get better

the s9 got better.

it will be interesting to see if the m10  stays trouble free.

[sarcheer]

Do the fans on the PSU spin when you try to re-power it up? More wondering if it is giving any indications that it is responding to input power.

The PSU on my T15 is not hot to the touch in normal mode in a ~75ºF room. I will check and confirm come Monday that this is still the case.

[philipma1957]

So on your power meters you read 200 ?

I am asking since you could drop under 200 if you normally read 200.

The gear says 200-240.   So if 243 kills them. What would 195 do?

My guess is a shut down.
My next guess is   Low setting will be fine for s15 or t15.  At 190 to 250.

But. High speed you will need to be say 201 to 238.

I would ask for those with the gear to read volts suppiled and speed you run at.
Maybe we can get an idea if this is true.

I had asked blokforge to sell me one via cc.  He missed my pm and when he contacted me I had purchased 8 k in other gear.  So I will be needing to mine longer before I get one of these. As I will no longer purchase direct from bitmain due to trump tax.

I may get an s15 from a private sale in feb. Till then I won’t be testing or showing them.

It is important to see if the psu really needs to stay inside 200-240 to run high speed safely .

So those that have them please give us info.

[HagssFIN]

I have ordered one S15 from Bitmain and I will do a review when I receive it.

[sarcheer]

Multimeter tells me my PDU is distributing 200v regardless of load, my panel is labeled 208v however. I haven’t had power problems (no dead psu’s) in the year I’ve had this panel under 24/7 load. Temps ranged from 65 to 95 over that time as ventilation and A/C changed.

I’ve only run my T15 in LPM for 3-4 hours since I received it on Tuesday and I’ve had no PSU problems. So, based on available info, we can preliminarily say that the APW8 tolerates the low end of its rating better than the high end. It will be interesting to see this range better defined as more units enter the field.

So my stats are 23.35 TH/s at 200v, 7.6 Amps

[ConnerM]

Do the fans on the PSU spin when you try to re-power it up? More wondering if it is giving any indications that it is responding to input power.

No, nothing. Units are totally dead. No Hash boards, fans, or lights on the controller. Re-power produces nothing. Leads me to believe that the PSU's failed due to the voltage. Really want to open one up and do some testing.

philipma1957 is probably right, the voltage from my 240 outlets here at the house probably varies by couple of volts up and down. When I test them I was reading 240.8v. Most appliances designed for 240v power have an outside operating range of 250v due to variance. Not these guys, apparently. Oh, was definitely running them full power mode. They were running about 28.4 when they were up. I should have switched the other unit to low power mode when the first one failed, but I wasn't thinking it was a voltage issue until they both failed.

[philipma1957]

Yeah this likely it a spike above 243 is common in my area.  Even 245 can happen.

I almost never drop below 237.

And of course my 120 is often 121 or 122 and I almost never drop to 118.

I am guessing full power at 243 volts + equals psu death

We will need more confirmation of this to be sure.

We need a spare psu or 2 to test top limits.

This could be a real issue to USA miners as many of us get 238 to 245 for our 240 lines.

My new buildout with buysolar will be 40kwatt constant 240 but it could flux to 245.  This means no s15 or t15 on the 240 lines.

Although this guys warehouse has.

208
240
480

So if we do some s15 we will do it on the 208 . If someone can get spare psus we can test at 245 and see if there is a burn out at low power setting on the miner.

[sarcheer]

If your voltage is too high I don’t think running at LPM would have made a difference, especially if these PSU’s are as sensitive as they are appearing to be. What’s strange is the previous APWs were advertised as having “overvoltage protection.” Where was that for your units? Really hope Bitmain didn’t scrimp on these PSU’s.

Link to info below in case you’re interested in removing your APW8 and giving it an inspection:

https://support.bitmain.com/hc/en-us/articles/360013898033-How-to-detach-APW8-PSU-from-DR5-S11-S15-T15

[philipma1957]

Well I have gone as 247 very rarely. So if 240+ is an issue on both low setting and high setting I can’t use these that easily.  Lots of USA buyers will be complaining since lots of us go from 237 to 245.

Maybe it was just bad luck.  Years back the s7ln would have issues.  And the s4 or s2 had psu issues.

This will need to be watched for carefully.

[mikeywith]

it's quite the opposite, high speed require more current therefore more resistance and less voltage.

the more "power" your miner "takes" the more drop in voltage you get

in more details.

assuming your voltage reading "unloaded" 240v.

if your miner needs more power , it asks for more current from the source (volt) , the more current that moves thought the wires, the more heat it generates, the more heat the more the resistance, the higher the resistance the less the volt.

so your miner needs 5 amps 240v might drop to only 239.
but if it needs 7 amps 240v might drop to 238.
if it needs only 1amp it might stay at 240.

all the above numbers are nothing even close to reality, but just an explanation, you could have your miner at full load and it may still fail to generate enough resistance that is capable of dropping  the voltage by anything measurable.

The gear says 200-240.   So if 243 kills them. What would 195 do?

low voltage can damage your PSU , the psu has an ideal rated power of Volts * Amps it needs to keep it at x value
if the voltage drops it will try to cover up by drawing more amps (current) , and as explained above this will cause more heat , most of the times more heat than what your PSU can handle and that = psu damage.

but usually those psu come with voltage protection, which indeed is not perfect, but i am pretty certain it can handle at small drops and spikes.

[philipma1957]

well so far one guy with 5 units

running 3 at 208 volt input  high speed = good to go

running 2 at 240.8 volt input high speed = dead psu's

not enough to say  gear is fucked up

but enough for all owners to watch units carefully  and make notes of the input voltage.

another guy  with 4 units all four at high speed.
2 run hot and shut down
2 run okay and don't shut down

It is new tech and bitmain has had new tech struggle during early batches.

fanatic26 usually has a lot of gear running.

maybe he can post  his s15 numbers  if he has them setup.

[Artemis3]

well so far one guy with 5 units

I'm willing to guess their PSUs are optimal for chinese mains, which is 220v@50hz...

know this thread is relevant to S15/T15...but isnt the S11 based on newer chipset(7nm) as well?

[sarcheer]

know this thread is relevant to S15/T15...but isnt the S11 based on newer chipset(7nm) as well?

I was under the impression it was as well, however I cannot find any info on the Bitmain website which lends any fact to that impression. The blog/PR post from BM about miners featuring the new 7nm chipset only mentions the S15 and the T15. The efficiencies of the S15 and T15 are a significant jump from the S11. The S11 has 252 chips on 3 boards while the S15 and T15 have 288 on 4 boards and 180 on 3, respectively.

The above factors lead me to believe that the S11 is in fact using 16nm chips and was probably their "improved" S9 they intended to release had they not been experiencing such financial difficulty.

Our s15 adventure continues. This morning we shipped the (2) S15's that failed on 240v to the CA repair depot. This afternoon 10 more S15's arrived from BitMain. We put them on the 208v rack at the office. Of the 10, 7 work perfectly and 3 will not show up on our network despite all efforts and troubleshooting. Can't figure it out. So now I have 13 S15's running, 2 going back for PSU, and 3 that boot up but won't communicate with the network. I wish I could get ahold of a couple of spare PSU's and controllers for these guys. They aren't selling S15 parts yet, are they?

Are you getting both blinky lights from the Ethernet ports?

One thing, which I assumed was because I swapped an Ethernet cable from an A4+ to the T15, is that when I powered up the T15 is it stole the IP address from the A4+. Given this may not be an isolated incident caused by my switch, are you using static IP’s or dhcp? If DHCP, you may want to move all the existing miners to static IP’s and see if the missing miners start showing up.

Definitely have normal connectivity lights. Machines boot as normal, all lights normal, but cycle due to not having a network connection. When we plug them into the connections of working machines, they do not come up. All the miners on the network are static IP, but we have a DHCP range set aside on the router for new machines. We boot them DHCP and then assign static IP's.  Power cycling and resetting the machines does not help. Switching PDU, power cables, and NIC cables doesn't help. Units do not show up in our routers control panel of connected devices. I thought perhaps they had shipped us units that had already been assigned static IP's, but a factory reset would fix that. I though maybe the NIC's were being finicky with our gigabit switches, so I put them on a 10/100 switch and also plugged them directly into the router. No joy. Not sure what the problem is, but if the controllers aren't bad we'll figure it out.

[philipma1957]

lets say  you do a sub net.

your main router is say  192.168.0.1-256

add a cheap  router  that is 192.168.1.1-256

so modem >>>> main router >>>>> cheap subnet router >>>>> attach 1 bad miner attach 1 pc  search with advanced ip or angry ip   see if it shows.

I had issues with early model s-9's  sound like this issue.

So  2 dead psu's
and 3 weird ip's out of 20 units correct?

To late now but the s15's in your case should have  been m10's

My 4 m10's = flawless  they do 59-60 watts  a th at  low setting about 20.5th

are you usa based?

[Artemis3]

If its only diagnosing, you can connect a pc directly to the miner or via an isolated router and scan.
If its using dhcp, check its log and immediately catch any assigned IP.

That is: Take a router with dhcp enabled, don't connect it to internet or anything, just a PC (or smarphone) to catch is web ui, and the miner and see if it gets an ip assigned. Else, do the port scan from the pc itself.

There is also a third option more advanced involving serial port console access via the lan port of the miner, I think the S9s can do it, perhaps the S15 can as well?

[fanatic26_]

Each of my technicians is armed with a $30 cheapo netgear router because their base firmware will find any IP that is connected via ethernet even if it is not able to communicate with the unit. We have ffound some really strange network settings on machines this way.

An IP reporter factory reset should be all you need to get them back up and running unless you got a batch with corrupted controller firmware from the factory or something

I got the shipping notice today.

I have not given them any KYC data (passport etc.) they have been asking,
yet still I managed to get my order through.

I paid via bank transfer.

[philipma1957]

KYC  
they have my home  address  
they have my home phone
they have my Social Security Number
they have a copy of my drivers license

my name is rare so rare  that I have never found any one in the world with my name going back to 1900.
lastly they have sent 50 packages to me since 2013

that is enough for KYC.

I placed an order but did not pay and I think they would have shipped to me.

I am considering buying a T15 maybe a S11  I will hold some money aside for  a S15  from someone you and I both know well.

[minefarmbuy]

Yea, I don't think Bitmain is going to be too picky right now with sales.

[sarcheer]

Given this is my first all-new Bitmain (BM) product, if you exclude the S7-LN because it wasn't using new chips, I'm in the strange position of hoping BM stays around so they can properly support my investment. Since getting into mining in 2016 and subsequently learning of BM's bad actions this is the first time I've felt this way haha.

Maybe I'll settle with my conscience by hoping they keep operating but on a much smaller scale?

To make it clear why I am sharing these thoughts in relation to this thread, I've noticed that someone in this thread with a T15 that shipped after mine is on firmware dated December 29th, whereas the FW on my T15 is dated December 18th, which is also the latest officially listed FW from BM. Why would they ship the next batch with newer firmware and not list that fw for download? Are the batches different in terms of hardware? If they're different, why not give them a distinct subgroup and list that different machine's FW on the support page?

Which brings me to why I worry: are things at BM so bad that the chaos in the C-suite is affecting decisions regarding FW releases and support? They've released 3 new ASICS with integrated PSU's without offering any way to purchase the PSU (APW8) on its own, let alone share the specs on the PSU so we can be informed on our machines and ensure they're being run in the proper environment.

[fanatic26_]

fanatic26 usually has a lot of gear running.

Unfortunately I was only able to get my hands on T15s out of the first batch, so I have nothing to report on the S15 as of yet.

[ConnerM]

and 3 weird ip's out of 20 units correct?

are you usa based?

Yep, Northern Virginia. We have 8.4cent power on an annual contract with the PoCo here.

So, update. we got 2 more S15's in today. These are 2 of the 27TH models. Put them on the rack and they came right up on the network. So for the 3 that were giving us trouble, I took a laptop and a little VPN router that I have and direct connected each unit to the laptop via the router, then ran WireShark and found the IP the S15 was broadcasting. That got me in, and I programmed a static IP to each S15, reconnected, and they came up just fine on our regular LAN. Not sure what the issue with getting a DHCP assignment is for these units (they are running the same firmware versions as other units that worked fine to begin with). In any case, have 18 on the rack now running 100%. The two units that had the PSU problem at 240v already went back to bitmain for warranty repair.

Onward and upward.

Maybe your dhcp server is having trouble? That's one more reason i would recommend to set networking manually in all miners. Perhaps the only moment you'd need dhcp is when its brand new and you need to log in to configure it the first time into a proper manually set address, like you just did

[philipma1957]

yeah it could be
a shitty switch
a crappy router
a bad wire

may not be the s15's

Do you use fios?

I just got back from a 60 rig build out and fios is a pleasure to work with compared to cablevision/optimum/altice

Fios seems to always do Dhcp up the line   ie
1.1
1.2
1.3
1.4
1.5
right to 1.256  Super fast to search it with angry ip, advanced ip etc  please to do a build out if it is Fios served.

I'm not sure. We have a Cisco router that is up to date and latest firmware. We have 36 Z Mini's and at one time 104 S9's of every generation running on it, plus maybe 20 odd computers and devices around the office. We always assign static IPs to the miners, but allow a pool of 50 DHCP addresses for miner bootup and for the other devices that don't need assignments and for wireless devices. Never had a single problem before. We tried swapping cables and even direct connection to the router past the switches. I did open up a ticket with Bitmain support and she said it could have something to do with the way the controllers were flashed. The three units we had trouble with do have the black label around the network port and control panel, and the others do not. I'm not sure if there are any differences in controller hardware, but at Bitmains suggestion we did swap a controller from a working machine to a non-working one and the machine worked fine with the other controller.

To late now but the s15's in your case should have  been m10's

The last batch if 10 S15's that we acquired was during that little blip when Bitmain was selling them for $1050. Between that and the coupons we had, it paid for the tariff and shipping. The M10 looks like a good machine but @ 65w/TH the efficiency is too low. We're planning to deploy a total of 36 S15 by the end if Jan and run them full power the rest of the winter. That will give us 1PH. Then change them over to LPM starting in May when we start to have cooling challenges. Our mining room should be able to keep up with the heat very well with 36 machines running 850w ea + the Mini's, and we will be mining at a more efficient ratio during the May-Oct when our PoCo increases our electric rates slightly. In order for us to keep our contract rate with the PoCo we have to draw at least 60KVa 24/7, and in July I want to renew that contract for one more year. We subsidize the electric cost for the mining operation so this will make that more manageable and I'm hoping this last equipment upgrade will keep us mining until the halving. Can't really see beyond that, but I don't think there will be anymore new form factors or revolutionary new increases in efficiency in the next 18 months, so this is what we came up with to keep us mining for one more generation of gear. We can support up to 80 S15's on the current rack (we have total capacity of 150KVa), and our power cost goes down the more we use, so if the gear gets cheaper later in the year we can add more capacity if conditions look favorable. We've been mining since the S5's, so this will be the fourth cycle of gear we've gone through.

Also, I would like to give a hat tip to BitMain. They received the first warranty repair miner (one of our S15's that failed on 240v) in CA on Wednesday and dispatched a replacement unit from Shenzen this morning, it's due to arrive UPS on Monday. So about 10 days turn around from VA. Never thought I'd ever say that.

But the M10 is 16nm while the S15 is 7nm. Don't you think MicroBT will come out with something 7nm in less than 18 months? Bitmain is losing ground IMO.

[sarcheer]

The case could be made that MicroBT has no experience with 7nm (in terms of produced miners) and may not be as successful with the efficiency advantages they eked out from 16nm, the node size they've been working with for what, 3 years? They also may not have the capital to purchase/manufacture 7nm chips at a scale which will allow for a price competitive product.

[philipma1957]

The real question is does the s15 psu fail a lot at 240+ volts

the m10 so far seems bullet proof.
the s15 does not seem bullet proof.

My new build out with buysolar is the biggest yet.  I could do 40kwatt "free"  plus 50 kwatt "pay"

So  right now we are up to  48kwatt and I want to continue to add more units.

3 to pick from  
S15
T15
M10

If I knew what the 240 volt psu issue really was about I would get s15's.

I don't know yet.

I will say  Apw3++  can run  with zero issues at 243 volt for months  been there done that.

[sarcheer]

What would make me feel way better would be for someone to figure out how to power a T/S15 with an APW5 or something similar. I'm far from an EE and based on what others with more knowledge have said about the efficiency gains all these new machines receive from integrated PSU's, I doubt it would be possible without some serious jerry-rigging.

[HagssFIN]

Bitmain describes the APW8 power supply (which is the psu for S11, T11, S15, T15) as a 16 - 18 V_DC power supply.
I think that this means the controller board is able to control the psu output voltage fed to the hash boards.

then  buying an s11  for  512usd    using a coupon

https://shop.bitmain.com/product/detail?pid=00020190104175252854y6zoVRs606E1

just run the s11 at low speed

https://shop.bitmain.com/product/detail?pid=00020190104175252854y6zoVRs606E1
   
 "SHA256   s11

it would be pretty efficient.   cost would be around 600 if you have a coupon

That is my thought as well. Doing all regulation in the PSU vs using the normal 2-stages (AC line > PSU 12v > hash boards 7 or whatever volts) certainly kicks up the efficiency. Has anyone looked to see if there is a coms cable going to the s15 PSU?

I would think that the Pangolin and Inno miners should do the same thing.

[HagssFIN]

Has anyone looked to see if there is a coms cable going to the s15 PSU?

Yes there is one.

It's a 4-pin data cable.

You can see it in this Youtube video they have posted at their website.

I confirm, In kernel log, I can see 16.5 Volts chain calibration also at 18 Volts.

If you don't change pools 1 and 2, you will be giving money to Bitmain from time to time...

I know this and kinda left it there in the screenshot to be teaser, it rarely drops to backup pool as the screenshot shows I have mined successfully without dropping to giving charity to Bitmain. For month now. It is intentional laziness I'm rebel lol or stupid.

Looks like a price drop here. Coupons are still usable. If anyone here runs an order I'll give you my 2 $65 just send me your order number through us.

the s15 is still too high at 1020 is going to get taxed if shipped to usa.

so I am looking at  what price if I order one from you?

the website reads  1650 solo with custom support.

does this reflect the drop to 1020? pre tax pre shipping

and the 65 dollar coupon

I am guessing no.

[HagssFIN]

I now have the S15 running,
and as guessed, it is a noisy beast..!
Mostly because of the psu fans.

I'll write more about it later on,
but here is a quick video for noise reference.

It's all projection with our model. Most to all clients get a return of surplus funds or we eat the cost from our commission.

I just have to get the order number to and give them the coupon to apply and then it's detailed out on the final invoice.

[philipma1957]

my used s15 arrives today.
from a forum member in finland.
usps.com says out for delivery.

based on reports of a few psu's burning out I will use a regulator and keep power at 220volts vs 240 volts.

I will post a few shots later today.

[HagssFIN]

^ That's great news!

[philipma1957]

^ That's great news!

I will preheat unit with an s7ln

Edit

Since it arrived 5 min ago ice cold.

lots of  full sized shots

due to the cold weather today it arrived very chilled.
I am warming it up with s7ln heater/miner
I like to use this unit to warm and dry gear as it is very quiet and only 500 watts on the setting I use.  this allows the chilled unit to dry and warm up more slowly.
Note I will rotate the s15 so that it gets 15 minutes on all six sides.

Better safe then sorry

[fanatic26_]

Better safe then sorry

I must say electronics on carpet like that with the risk of static shock when touching the unit would kind of worry me. Id place an anti static mat under those personally if they had to be ran on carpet or a rug like that.

you are correct if you look at tv set shelf in the picture there is a grounding bar just at top center

I ground myself on it before I touch units.

I moved unit into garage for testing over the week end.

I did a you tube video.

it is not ready uploads are slow.

link:

Your video will be live at: https://youtu.be/auakWENgP8w

you will note unit is laying on fiberglass welding blanket in a sound proof setup for the testing it is shock protected.

Sound meter failed at end of video so I will do another one later today.

the gear works very well in garage and I certainly could run it

without pissing off my wife.

1625 watts and 27200 gh =  59.7 watts a th

so if all s15's do 1625 watts and 27.2 th
and my m10's do 2200 watts and 31.2 th

both on full speed it will be a hard call as to which to pick.

s15's cost me  a lot more then m10's

maybe  1650 with trump tax. 1285 without tax

m10's are under 900 without the trump tax.

So far  My math shows me the s15 has to net to 1000usd  to equal an m10 at 875.00 usd

So If I expand I still favor m10's with the pricing I get.

m10 at 875 no tax
s15 at 1285 no tax

note running on mmpool there is no asdic boost
so the 1625 watts could be better on pool.ckpool.org
will make a new video on SAT testing other pool

[judypug1956]

Did you post a newer video on youtube to show the corrected sound readings?

[philipma1957]

Yes I did but slow uploading time again.

I also moved off mmpool.org a none asic boost pool  pulling 1621-1625 watts

to pool.ckpool.org an asic boost pool

1547 watts  same hash rate  and a 75 watt savings

video is not up won't be up for a while

[TheYankeesWin!]

SO the videos are up.

Runs pretty quiet Phil .

Did you buy a transformer to set power to 220 vs 238-243  you normally get?

[philipma1957]

@ yankees.

I purchased this item  in theory it will put out 220v +/-  5%  so 209-231

https://www.amazon.com/gp/product/B071V5NXZV/

My input is 243.1 and my output is 220.7 on my hand held meter

the meter on the unit read 243 in and 220 out.

I am testing it with an old s7ln  before I put it on the s15

I will post a photo very soon.

Since it is the 5000va model  I think  it can do 2 units.

of course you need to feed 240 in to run 2 units.

I am using this to stabilize not step up 120 to 220  or step down 220 to 110
To be safe I am running a cheap piece of gear on it. Not the s15

[Artemis3]

I have a similar device, but you can't feed mine with 120v, the min is like 180v or so.
I'm powering a quiet R4 at home with it, but it can power an S9 just fine.

From two phases (our residential service is like that in US for office buildings) i would theoretically get 208v, but... a tester shows 203v. Thanks to that device, the R4 is actually getting 220v just fine, and the electricity here sometimes fluctuates so it has kept the miner happy (its NOT using an APW5 mind you, but some hp server psu with an adapter).

[philipma1957]

yeah  I can feed it 120 or 240

and make it send out 110 or 220

The cable  is 14 gauge  which can do 15 amps.  It is rated to do 22.7 amps continuous but with the cable they put on it   it is more like 12 or 13 amps 24/7/365

13 x 220 = 2860 watts  

which would be 1 s15 at low   and 1 s15 at high   say  2500-2600 watts 24/7/365

if I get in the mood I may  open it op and see if I can mode it to do 3500 watts 24.7.365

[ConnerM]

My input is 243.1 and my output is 220.7 on my hand held meter
the meter on the unit read 243 in and 220 out.

I was looking at a Larson Buck transformer to change the 240 at my house to 220 or 208 so I could run a couple of S15's at home, but it's not really cost effective. Also, they show a 3-4% loss of efficiency in the windings due to heat loss. I don't think you can step down the voltage with any device and not experience a certain small loss in the process, so keep that in mind when calculating the cost to run an S15 vs say an M10. With a transformer an S15 might end of drawing 60 or more w/per TH. It would be great if Phil could test that on his device.

We now have 28 S15's running on the rack at the office now on 208v, and they are functioning perfectly. They are all 28TH units. The min to min hash rate variance is higher than spec, can be up to 15% either way, but the daily average of the units collectively is 783.9 TH which = 783.9 which is 27.96TH per machine on average, so they are running exactly within spec on our 208v supply. Power draw is averaging 1590w per unit. That's based on the total draw on our panel. I haven't measured individual units.  We're using Triplite 3' 12awg power cables from the PDU to the units. One miner per PDU circuit, 2 miners per PDU so the breaker on the PDU's become the power switches. The 12awg cables are to minimize loss more than anything else, I don't think we would have any trouble using 14awg cables for these as long as they are short. This is all equipment reused from the S9 farm.

Bitmain replaced our 2 units that failed on 240v+ for us under warranty. One of the replacement units came with the 'open power rail' design (which bothers me greatly). All the other have the power rail covers.

Oh, also, the DHCP network problem we had with the 2nd batch of arrivals was unique to that batch, 6 machines. We had to plug those into a small router and scan for the IP address, then change the settings to a static IP on our network. All of the new arrivals come up on our network fine at boot.

[philipma1957]

I did test it  and it appears to cost 1.5%  in power. About 25 watts at high speed.

 also took it apart to figure if it really is 5000 va and 22.7 amps constant run.

I estimate it will do 1 unit at 1550 watts 24/7/365  with zero issues.
I don't think it can do 2 units at 3100 watts. 24/7/365
I think  the torrid transformer will get too hot.
I also think the power cord is  14 gauge  not 12 gauge.
So  for 1 unit in a garage it is okay it should protect the gear and last  but it won't last doing the 2 units it is rated for.

It is now on sale on ebay

https://www.ebay.com/itm/Norstar-5000-Watt-Step-UP-and-Down-Voltatge-Regulator-Transformer-Converter/332955089461?

I bid 180 offer he took it.
and ebay is giving ebucks 10%  so 180 -18 = 162  and my paypal gives 2 % so 162 -3 = 159

for 159  it will give me some piece of mind.  but  if you have  10 or 20   s15's this costs too much.

[minefarmbuy]

So running these on 240v is a bad idea?

[ConnerM]

So running these on 240v is a bad idea?

I took 2 S15's home (to run for heat) on my 240 outlets and the PSU's on both units failed within 24 hours. Both PSU's got quite hot. I think my 240 outlets actual voltage may vary a little higher than that, maybe 242 or 243. They may have simply tripped a safety shutdown due to either voltage or temperature, but regardless, both ceased to function (no power) there was no way to reset them. Both units went to Bitmain and were replaced under warranty. I will not attempt to run anymore of these at or near 240v even though the spec says 200-240v. They seem to be happiest somewhere in between those numbers. I've had some units running nearly a month on our 208v rack with zero issues.

[NotFuzzyWarm]

@Phil, since you opened the regulator to look at it, does it use relays to change taps or is it solid-state (SCR's/Triacs)?
Long ago I tried a el-cheapo regulator like this one and found it unusable because of too-small transformer and the relay switching times. Every time it would make an adjustment the momentary v drop as the relays switched would cause the miner to go offline. My solution was to use a programmable dual-conversion UPS like the TrippLite SU6000RT4UHV—6kVA that is always on-line and has zero transfer time. It's in/out eff is reasonable at a measured 93% in dual-conversion mode and >96% in eco-mode.

[Steamy27]

Is anyone having this issue (240v PSU failure) with S11's? T15's?

[ConnerM]

I did test it  and it appears to cost 1.5%  in power. About 25 watts at high speed.
I also took it apart to figure if it really is 5000 va and 22.7 amps constant run.

So  for 1 unit in a garage it is okay it should protect the gear and last  but it won't last doing the 2 units it is rated for.

Keeping the unit low spec will also minimize the power loss factor. 1.5% is excellent, and the price is right as well.

The Larson transformer I was looking at was 11KVa (TX2402081P11KVA) 240v to 208v (max 53 amps) and costs about $600. I could run about 5 S15 off it with a solid safety margin but it would require extensive rewiring of my circuits.  Not worth doing for a couple months of heat at the house.

[philipma1957]

So running these on 240v is a bad idea?

One guy had two psu fails.

ConnerM

He was doing just over 240 volts.

Ah this is complicated but here goes. I am color blind so I never was able to do formal training in electronics.  But I have a decent knowledge of parts and gear.  They took one leg of the 240 in and run it directly to the outlets.  So if you have a hot 240 like I do one leg is not altered at all.

The other leg goes into a torrid transformer a 110 to 100 volt.

So this means a 122 leg goes in and it is not touched.
The other 122 jet goes in and is dropped by the transformer to 100
It then feeds into some relays and parts that drop to 98 and the 98 plus 122 = 220.

So the legs are not even but they sum close to 220 vs 238-243
And only one leg runs into the transformer.

Also they lift the ground which is not exactly how I would do it.

I cut the two prong plug 🔌  and put a three prong plug. I still lifted ground but I think I will add back ground.

The design does allow for a lessor transformer .  But looking at wires gauge and other parts I think it won’t do two units.

Since only one s15 user has had the psu burn (two of 15 to be exact) .  Maybe it was just a couple of shitty psu's. Meaning these regulators are not needed at all.

[sarcheer]

BM site is saying coupons up to $230 can be used for both the S15 and T15, has this always been the case?

[Steamtyme]

Yes I believe you could always use those coupons.

I was looking to buy some as i was on the fence between an S15/T15 with a coupon, or the M10. So at least going back to around the 12th of January.

[philipma1957]

The T15  with a good coupon is not that bad a deal.    It is 710 + 102 to ship to usa

it beats the tax.  as it is under 800 for the gear.

it nets to 812.  so a 230 coupon drops it to 582   that works when compared to the old m10 prices

and is better then the new m10 price.

I am not sure anyone has a 230 usd coupon for bitmain the may have expired.

If I could get a few of these  with a could coupon it may be worth it.

[minefarmbuy]

T15 in LPM beats m10 stock. Best unit to import to the US imo.

Yea just saw the twitter posts.

Only accessible with poor network security correct?

[philipma1957]

Anyone tested with S11 LPM ? It's suitable for home mining?

I doubt it.

It uses same psu as the s15

It uses 1024 watts on lowest setting

the s15 uses less watts on the lowest settings.  like 900

Here are the s15 soundproofing videos I have done

https://www.youtube.com/watch?v=auakWENgP8w

notice it fires into  a cushion  placed 2 feet away

this one the sound meters more accurate

https://www.youtube.com/watch?v=P8MwWwctWVw

I am pretty sure the s15 is better for noise

[Steamtyme]

Have there been any more reports of issues with the PSU's. I'm kicking around the idea of an S15/T15 not to sure yet. I'll have to do some more more testing but I believe I've seen my lines hit above 240 when testing after installs.

I did have to have a check back to see what there APW7's were rated at to see if I felt like risking it, but they were rated up to 264V.

so far just the one guy.

[Steamtyme]

Well it appears the S15 is currently sold out, so that may not be an option for anyone wanting to use those coupons on the 26th.

I do see the T15 is still in stock, and is the cheaper option per TH with the 250$ coupon. (compared to the M10 @799 with coupon)

Edit: Cheaper with any coupon 120 or larger.

[minefarmbuy]

Well the 395/300/195 coupon are ready for use right away, So not surprised the s15 is sold out.

[Steamtyme]

That makes sense. I figured they had to be out there, as they were mentioned on the site, just didn't know anyone who had them.

I have the same batch as most that become valid on the 26th (340/250/160).

[sarcheer]

Can't wait to see these cheaper units show up on the secondary market!

[philipma1957]

yeah I noticed this.  so no s15's

[minefarmbuy]

I'm sure there will be a March batch listed from them Sunday night or early next week.

[sidehack]

Darn, I was thinking of picking one of those up.

[Biffa]

My coupons still not valid till 26th 

[Steamtyme]

Yeah it was only the larger coupons that went to some of their preferred larger clientele I imagine. So the 395$ as opposed to the 340$, and the 300$ as opposed to the 250$

I haven't talked to anyone who held those coupons so I can't be sure when or how they were distributed, but apparently they were usable at any time.

[minefarmbuy]

typically it's just seems to be most recent clients who receive the coupons here.

[fanatic26_]

Here is my breakdown of coupons:

The 5392 represents the number of S9s we purchased.

5392x$340
5392x$250
5392x$160
5392x$65

The 2 represents the 2 T15s I purchased for testing.

2x$395
2x$300
2x$195
2x$100

This should give some idea about how they were distributing the coupons.

[minefarmbuy]

You should have received more for your recent purchases.

Using a single unit example from s15/t15 sales should have netted all of the following coupons. We haven't had any movement on the s11 which is odd.

1x $395
1x $340 live 2.26
1x $300
1x $250 live 2.26
1x $195
1x $160 live 2.26

[philipma1957]

t15  is now allowing the $250 coupons

Payment Address: 3AbjSf2vKK2AU6uqhMUjGpPQZGVbqg3HNb

Order ID: 001201902260xxxx

1 BTC = 3900.85 USD

[Steamtyme]

Nice that's good news looks like it can go up to 300 or less.

Where these always scheduled to ship april 1- 10? I think I'm just going to go for it I'm a touch worried about the over 240 but am willing to chance it.

[minefarmbuy]

Last batch was dated Feb 15-25 I believe.

[philipma1957]

Yeah the longer date is given to make up for the coupon.

60 days of waiting for the t15 is close to 250 usd value for a free power guy.

224 for two month delay

[PeaMine]

That didn't take them too long
https://blog.bitmain.com/en/bitmain-announces-next-generation-7nm-asic-chip-for-sha256-mining-delivering-breakthrough-energy-efficiency/
My post in it's own thread got deleted for some reason.  I would assume S15 and T15 are about to drop in price.

[minefarmbuy]

Maybe after coupons expire. At least Bitmain and Canaan price well compared to others.

[digital$]

im assuming S9's wont be available in future only S&T series from here out along with their 2nd revision models

So can you no longer ssh to it? Make sure you keep backups of the older firmware!

[JonnyRocket]

I loaded the new firmware on a T15 that was taking forever to boot up and now it is rebooting itself every 30 minutes or so. Maybe it is a firmware issue, maybe it's the miner...

Has Anyone else have any issues with the new firmware? I went to flash the old firmware from an older T15 but it seems they have made it so we can no longer download backups from the interface. How can I find the old T15 firmware?

[Steamtyme]

Looks like the T15 has also sold out for April delivery. I held off on ordering when i realised it was more than a month until shipdate. It's a little short sighted on my part.; but i have no need to take 28TH of inefficient 741's offline until May.

I have decided to take this time to reach out to Bitmain support and ask about max input voltage of 240. I know it wad only a couple and could have been a cold/moisture issue, but it doesn't sit well with me to have a potential problem that would definitely void the warranty.

I am the worst at pulling the trigger on new gear

So bitmain is sold out of

S15
T15
S11

innosilicon is  insanely expensive with a long wait for the T3

M10's are the only new gear around at the moment.

[minefarmbuy]

We'll see whats available Sunday night. Looks like our orders we're all submitted to them yesterday.

Might be tough on timing for the next batches as these last were a month away.

[mikeywith]

Yeah it was only the larger coupons that went to some of their preferred larger clientele I imagine. So the 395$ as opposed to the 340$, and the 300$ as opposed to the 250$

I haven't talked to anyone who held those coupons so I can't be sure when or how they were distributed, but apparently they were usable at any time.

here is a breakdown of how they distributed  the coupons

For every S9 bought they gave out 3 x coupons with face value of (160$,250$,340$).

For every S11/T15/S15 they gave out the same as the S9 + another 3 coupons with face value of ( 195,300,395).

those who want buy new gears from bitmain should buy those higher values coupons, even if they have the s9 coupons in their account.

S15 coupon   395 - 340  = 45$ , so anything you pay that is less than 45$ = more saving

same thing goes for the other coupons.

[Steamtyme]

Yeah I noticed that before. I actually got all those same coupons for the 1 miner I bought direct - it was a T9+. Funny thing is I bought it with a very good coupon as well.

Either way I'm going to hold off until I hear from Bitmain. Without a solid yay or nay I won't risk having the failure, my power costs allow me to happily buy m10's in the meantime.

[mikeywith]

it's pretty much safe to assume that anything above 240v will put the psu in danger, i also wouldn't take bitmain support word's very seriously.

if you have a constant >240 voltage then that will be an issue, but if you are only worried about once in a while spikes then you can use something like this > https://www.aliexpress.com/item/60A-220V-adjustable-automatic-reconnect-over-voltage-and-under-voltage-protection-device-relay-with-Voltmeter-voltage/32814064058.html

it's more or less a voltage protector, it does not regulate voltage whatsoever, but it does close the circuit when voltage is higher than whatever you set it to, same goes for voltage drop, i use something very similar to this "not on miners but on a sensitive fridge"  and it works like magic.

[minefarmbuy]

Looks like we're still waiting on new batches for the US market odd though that the CN site is pushing T15 for April. Wonder if our groups fill what date Bitmain give us.

Looks similar to something I was thinking of installing to actually monitor my power draw. Did I read it right that it opens the circuit and then re-establishes in less than 25 seconds? Problem is I'm not positive how often I go above. I may have to put more effort into confirming this if more hardware goes this way with a hard cap right at 240V. I would be okay with it kicking out the odd time, but would be hesitant to have it potentially cycle on and off several times in succession.

Thanks for the tip as I hadn't even considered something like this.

hmm set it to 239 or 240 or 241

it can do 2 x 30amp circuits  which is 6 s15's

[minefarmbuy]

T15s look available for now.

[Steamtyme]

hmm set it to 239 or 240 or 241

I'll have to head out to the garage tonight and check out the circuits I have out there, as that's where these would be installed. For my concern though I don't think the settings will help me if I'm consistently over Voltage. Those settings would be great for a stabilizer, at say 239 to keep it under their apparent hardcap for voltage. I am more concerned of the constant power cycling this device brings if I am indeed consistently over 240, sure I don't burn out the PSU by going over voltage, but flipping the switch on and off over and over again isn't going to help the equipment either.

To big a gamble for that bit improvement in efficiency until I know more. When I know I can run an M10 without worry, it's still the better option for me atm. I say this knowing that there is an S15 that I could grab in Canada for a decent price.

[mikeywith]

Not sure how are you going to make certain, voltage can change a bit depending on the time of the day, based on a few factors, so when you test it, it may be 238v but that doesn't mean it's not going to go any higher 3 hours later.

The easiest and cheapest way to test this to be 100% sure that everything will work as you want them to be would buy installing the voltage protector and using 1 of the miners you have (s9 or anything else), set the voltage peak to say 239 ,then watch the hashrate graph on the pool after say 24-48 hours, if you get a lot of V shapes then diffidently S15 is not for you  

* there are other ways , but i do think this is the easiest and the cheapest and requires 0 skills.

[Steamtyme]

Well at this point I'm saying the 15 series is not for me.

I did just do the manual checks on the unused summer circuit I have in the garage. The plan was to test it a few times throughout the day  as I went in and out while working on the house.

First test was 242-244V. Same results consistently for the next hour and a half. That's all I needed to see for now.

this is bad news, let's hope bitmain will revert to the old psu specs for the future batches.

well remember only 1 person  has had confirmed psu death at 243-247 volts

I would love to know if someone else has had this happen.

[Steamtyme]

True. Honestly if I had not heard their story I would already have an S15, or an order for a couple T15's.

I'm just not prepared to be the guinea pig. This would really sink my hardware upgrades to have a failure without warranty protection. The email request I sent for clarification has gone unanswered so far; which was expected.

[ConnerM]

well remember only 1 person  has had confirmed psu death at 243-247 volts

That was me. I tried 2 units at home back in January on separate 30amp 240v circuits, one in my basement and one in my garage. These are circuits I ran S9's on all last winter. Both S15's PSU's failed or fault tripped resulting in no power at slightly above 240v. My multimeter tests those circuits around 240.8v on average but they can vary +/- a couple of volts. One S15 failed almost immediately, within an hour, and the other ran for around 10 hours before crapping out. Both PSU's were noticeably hot prior to failure. I suspect the basement unit failed first due to the ambient (around 60f) being warmer so it over heated more quickly. The garage unit ran longer (ambient around 25f). Both units were returned to Bitmain CA under warranty repair tickets and were replaced directly from China in about a week.

We currently have 43 S15's running at the commercial farm on 208v, some for nearly 2 months, without any failures or issues though we did get one unit that had a bad hash board. Bitmain also replaced that unit under warranty in about a week.

I would not attempt to run anymore units at close to 240v without a step down transformer. Other than that, they have turned out to be fine gear. I have no complaints. They are all 28th/s units. Collective average for 43 units is 1.2Ph, so all machines are running very close to spec at 208v and 50-60f ambient mining room temp. Curious to see how well they hold up a couple of months from now once our mining room starts to get hot. We do intend to switch them into LP mode once the ambient starts getting into the 90's and mine them like that during the course of the summer.

One note - all 3 of our warranty replacement units seem to have come out of China stock and do not have the power rail covers, they are the open rail design. All other units we received have the rail covers.

[philipma1957]

I have a t15 on order and I should be safe up in clifton,nj  to run the s15 or the t15

but warranty of gear is critical for mining.

I am no longer tiny garage miner I have 530th + 40th = 570th  For BTC and I have 7.6 gh for LTC

But I did get a bad m10 I got parts today and now will go back to clifton to see if it is repairable.

The m10 was about 890 usd and right now it is hashing under 2th vs 31th

I got about 30 usd in earnings which is a net down of 860 plus I purchased 398 in various parts for the other six machines.

so that is 1258 in the hole or about 1 s15

when you buy the newer gear  and it goes down it is costly.

my share of the coins earned the last 2 weeks was 660 usd no cost for the power  but 1 good unit going down set me back
1 full month .   and even if I fix that m10  and the loss drops to 400 in spare parts it is an 8 day set back.

So for me to buy  3 or 4 s17's or s15's   it is a tough choice.

@ connerM that makes it easy for me to get some s15 or s17 as we are running at 228 volts in clifton

[minefarmbuy]

Gets to a point were an extra unit could circumvent the loss as there is no way to recoup time but then spare parts are essential for these machines anyway.

[TeslaWatt.com]

We got about 270 x S15 miners and we run them at 208v and 240v without single issue so far.

More S15 miners are coming our way. We are in Nevada so you can visit us anytime if someone wants to check in person. We are very transparent. Although this was March batch.

Also there are 2 models
S15 - 28 THs
S15 - 27 THs.

They are about the same in power consumption little bit lower.

Maybe I would send some s15s.

Got my S15 in last week, 2 dead hash boards, off to CA for repair.  Anyone have any idea on the turn around time?

Found the user and one of the posts I was referencing above ^.

[philipma1957]

I got a shipping notice for my t15.
I think it will come on Tues the 26th

It was supposed to be shipped April 1-April 10

I made these 3 post yesterday they were deleted this morning. Not angry in the least they were pulled as I feel that my gear was shipped because I posted these yesterday. Since gear is now on the way and shipped early these posts don't have to stay.  I do wonder has anyone esle had there gear shipped yesterday?

To be clear I realize I should have posted these in this thread not Hagss review thread.
I do wonder if  bitmain read them and decided to ship some gear out yesterday.

Mine are expiring and I never had an in stock s15 to use them on.

That is what I purchased 1x  T15.

Oh I finally decided to do the kyc  I photoed my NJ driver's License and they accepted it for KYC.

I would like to get the T15 early. would be nice.

[madmartyk]

I also received a shipping notice on my T15.  Should be here Mon or Tues.  Hope I have better luck than with the S15.  Comes in 2 bad hash boards, send it to CA, Bitmain send me a older (looked used) unit and it had a bad hash board.  So it's off to the repair center.

Then I start getting E-Mails that my coupons are ready to expire, use them now..  Problem is there is nothing to by with them!!  Everything is out of stock!!

[minefarmbuy]

Yea, bitmain is sending units out.

[ZimbaCardi]

Any news when they'll have stock? Any chance before the 31st?

[philipma1957]

Any news when they'll have stock? Any chance before the 31st?

it is about 8 am monday morning in china why not take a look at the website

[madmartyk]

Still same as before, the s9's and the dr5's  that's it.

[philipma1957]

Still same as before, the s9's and the dr5's  that's it.

They know how to work the sales.

I am sure many are hot to buy gear.


My T15 arrived running on low setting doing 20.9 th at 5 amps or 240 x 5 = 1200 watts

so this gear does 1200/20900 = 57.5 watt a th  that is much better then the specs

I will be looking for another meter to confirm that.

So the pdu meter reads 5 amps  and 5 x 240 = 1200

my more accurate meter read 5.45 amps and 5.45 x 240 = 1308 watts

so 1308/20834 = 62.8 watts a th pretty good but not the less accurate reading  numbers.

So no gear in site.

m10's = sold out
s15's = sold out
t15's = sold out

m20's = preorder
s17 = ?
t17= ?

oh my power reads 239-241 volts this will be moved to the Clifton Solar array on tues which provides 228 volts and I have 1 protection transformer left over which will do 220 volts.

All in all the t15 was a good price and on low speed is good with power at 62.8 watts

No info from fedex on trump tax I will post an update if they hit me with it.

[madmartyk]

What are the M20's??  Didn't see that when I checked Bitmain this morning.

[NotFuzzyWarm]

What are the M20's??  Didn't see that when I checked Bitmain this morning.

You need to look at other threads where they have extensive coverage... The M-series are from microBT and marketed as the Whatsminers, one distributor of them is Pangolinminers.

So far because the M20's are brand new and have not yet been delivered their thread is in Speculation.

[sarcheer]

To provide an update on the reliability side:

Both my T15's have been hashing away at 23.3 and 23 TH/s without problem for a few months now. Consuming 1475 W at 23.3 TH/s for an efficiency of just under 64 W/TH. This is at 208V.
