Any differences between T9 and S9?

It's like the late-S7 batches.
The same miner with less chips, little less effiency.

The S9 had 2 fans too..

When will the sale come out?

I would have preferred these over the R4's I just purchased - I guess them's the brakes.

Is this the end of S9? new miner will come? may be S10 or S11???

Power Consumption:

T9 1450W 11.5TH/s
S9 1078W 11TH/s (Batch 22)

The big difference for me.

That's a good point - I just realised the additional 29% power the T9 requires, @ 0.05 kWh that's an extra $160 per year.

Yeah, huge difference. If you have a free energy is not a problem. if you pay hosting this could be a problem.
Big plus is the warranty. Improved reliability? A 180-day warranty is provided starting from the shipping date.

Same cruddy firmware?

Same cruddy bmminer?

Same cruddy warranty?

Same cruddy pricing?

Same crud........

Wonder why they didn't call it the Q9 instead of T9 since Q is before R and S.

Its like BMW releasing a new cheaper, slower, less luxurious car and calling it the 9 Series.

So who's buying one?

i think they figure the reason of high S9 hashboard failure
it's the power needed for the chips!
so they produced T9 with 180 days warranty
each T9 board have 57 chips instead of 63 and need 480W to power instead of 400W
less chips more power!

Less efficient? Dunno why they're even trying now. Don't see many people buying one, at least the S7LN had a few buyers. If they did something like the LN with the S9 I'd buy it but just looks like the one fan variant of the S7 they did a while back.

In this state of technology 50% more power consumption as the S9???

I'm definitely going to try these out. I'm hopeful the decreased efficiency is offset by increased reliability.

Update:
Reliability has been great! Not a single failure from the first batch. Reminds me of the S7s.

Update #2:
We've got another 50 T9s arriving the first week of March. Check my signature if you're interested.

This seems like an acknowledgement of what everyone knows.  The S9 has design issues.  While we have looked at the A7 and could not figure out the huge efficiency differences between the Antminer and the Avalon in efficiency it appears that now we may know why.  This seems like an acknowledgement that the design has problems with the S9 and most likely the R4 as well. 

This would appear to put the T9 back on turf with the A7 for efficiency or getting pretty close.  If this is what it takes to make the miners stable and less prone to failure then so be it.  But now the T9 has to live in the shadow of the S9 which appears to be a more efficient miner that has hardware issues. 

So will miners gamble and keep ordering S9's if they become available?  Or will they choose stability and possibly reliability instead?  Maybe Bitmain will make that choice for us and just not offer the S9 going forward?

Since when has that ever been the case?

My guess is it's a cost thing. Bitmain just wants more money and nobody has a competitive product so they know they can get away with it. Kinda like they did with S5 and S7.

Is the purchasing link working for anyone yet?

Not yet for me

Hopefully reliability is ok for this one. I might buy this one.

ok, link is working. Max order quantity 50

I would buy a LN variant of the S9 as well.. 

I'd guess the lower efficiency is because they upped the voltage to the chips - could be the instability seen in the S9 and R4 units is due to the chips having barely enough voltage to run in Bitmain's quest to make the most efficient miner...

Up the voltage and you get less efficiency but possibly much more stability.  Just my .02BTC

Possibly.  I did receive an email direct from Bitmain making me aware of the release today.  Part of that email stated they would not release another batch of S9 until Chinese New Year ended so it doesn't look like they are stopping production of that unit.

Looks like still s9 still a good choice to buy than this because of the power comsumption and the speed of miner..
Much better to choose batch 23 asic s9.. but we lets see what will be reviews about this new release.

We went ahead and purchased 15 R4's and 20 of the T9's for our own operation. We will keep you guys updated and post some pics when they come in hopefully this week!

im jealous  lol , i wish i could afford to buy 5-10 or however many t9's , een being less efficiant then an s9 they would run for a very long time at my dc with my power rates

Another new variant of S9, but are we getting more S9's???

The efficiency comparison:

S9 11TH:
Power Consumption   1078W +10% (Batch 22) (at the wall, with Bitmain’s APW3 PSU,93% efficiency, 25°C ambient temp)

T9 11.5TH
Power Consumption   1450W  +7% (at the wall, with Bitmain's APW3 PSU, 93% efficiency, 25°C ambient temperature)       

Guys please don't be suckered in by this Bullsh*t

Stop letting htem get away with this

ALL this is, is bitmain getting rid of their poor run chips, that didn't meet 29 effeciency, they banked them and just put them together.

SAME reason why the batch hash rates varied, they put good/bad boards together in other packages based ont he avg hash rate.

This is another way for them to pass on shit chips that didn't meet specs, and make you pay for them

30-40% more power??? Come on!

Paid an hour ago using bitcoin, confirmed 4 times, yet my order status still shows unpaid..

Anybody had their orders confirmed?

Suspense is killing me :P

Ours is still unpaid,just patiently waiting...

Assuming they needed to use low quality ASIC's somehow. Easy to overvolt and this is their answer. Are they using them in their new data mining centre? doubt it, unless they are for investors sections of the mining center.  

If higher Voltage makes then run better. Why are we not seeing firmware to up volt the  R4 and S9????

In the case of the S9 it would mean you could only run it on 220v because the power draw would be too much for a typical 120v circuit... that is just a guess given the T9 is 1450w.

Same as other s9..
I hope that they  can release a good antminer that can run with low power consumption..
Or the speed is better with same consumption they are just releasing new but little bit similar.. of batch 22 of antminer s9.

I can't order, the add-to-cart link is not working. Is it sold out already?

Yes, although at times you can keep checking through the day as people don't fulfill their BTC transfers, I've seen them open it back up for sale.

Seem to only offer FedEx or DHL shipping.  I have bad luck with both.  Need UPS please!

Less efficient but a cheaper MSRP than the S9. Not sure if the trade off is worth it, but it's what Bitmain has given us!

You may be right about this strategy (in fact I think 90% you're on point), but I wouldn't blame a company for selling something people want. If people buy it they buy it and it's good business.

I too wish there was more competition. Personally I think as we approach Moore's law this will allow more competition to hit the market and also reliability of machines should improve as it will become more of a factor.

If anyone who purchased one of these new T9's wants to host them at a Secure, Clean Facility visit our website www.btcmeqc.com (http://www.btcmeqc.com)

Is anyone else getting this error when trying to check out?

 DirectPay generate bitcoin payment address error: null

I don't think they have been released for payment yet? As it said 2300 17th January (+0800 GMT).


He is right about this. The "new" chips are 0.001J/GHs at least less efficient than the previous S9 chips. Meaning that it is much more costly to run. I don't know why anyone would even consider buying one of these (hopefully the S11s will be better if/when they are released).

Estimated Next Difficulty:   377,934,006,315 (+12.18%)


Just about the perfect time to buy this miner.

made me spill my drink ด็้็้็้็้็้༼◉Д◉༽ด็้็้็้็้็้

 Same chip running at a higher operating voltage, thus the reduced efficiency.

 Up side, it SHOULD allow better overclocking at more reliability *IF* you can keep the bloody things cool enough, as they're not pushing the "bottom end" of where the chip will run at all (which seems to be a lot of the issue with the S9).

Is this available in the hashnest market? If not, I hope it does not take too long to be there.
Last year, the s9 miners took so long to get into the hash market that I don't think it was worth buying it.

Agreed. The power specs are rather on-par with the s9 batch-1 and 3 I have. Both use a high Vcore and are Hungry. At full rated clock of 650MHz the batch-1 tops out at just over 1400w after settling down from warmup (briefly >1500W). To keep temps down have that one clocked at 600 and it still averages over 13.5THs :D

Having owned various S9's from batch 1-23 I can tell you each evolution was an attempt to improve the design. I think this is also an attempt as with the recent batch of R4 machines to dispose of there lower quality chips from the production run. The easy solution to stabilize and poor quality chip is to give it more voltage. This draw more power which requires cutting the number of chips. I suspect this will be just a limited run while they hoard the best of the best last batch of 14TH machines which I had owned and was the best performing of them all. The added warranty is nice but considering this is an entire new design PCB i think it may also be prone to some premature failures while they might need to go through additional revisions of this board design to get it to the level of the last generation of S9's. This usually signals the end of a product line with them as I anticipate they are already in development of the next S11 based on 14nm Chips or a second round of 16nm chips with a more efficient design based on what they learned from the last asic

So the tip there is to either keep the temps low or undervolt the thing. Someone said on this thread earlier that the bitcoin miner only has one fan which I can definitely see would be a problem to anyone who wants to buy this miner (obviously I can't due to electricity costs).


It's not going to come. In the same way like the R4, R1, U3 and other miners didn't come. It is a sort-of partial release of a miner that comes out after the miner is made (such as the S3+, S4+, S5+...)
So we will probably never see it even go near hashnest.

Who would buy this on hashnest anyways? Uses more power, longer roi, worse everything compared to the S9. I wouldn't even consider buying it if it went on Hashnest. Bitmain doesn't underclock so you're looking at a full speed, high power and high maintenance miner.

T9 looks like a good miner for anyone who doesn't pay for their electricity.

Have they come and gone or has the link never worked?  It's 1/18 in China.

Looks like you missed the boat. They were available from ~2335 +8 GMT last night until a couple of hours ago.

come and gone. iv got 3 on there way to me along with power supplies.

Has anyone's payment been verified yet? I ordered and paid immediately after they went on sale - the transaction has over 60 confirmation now, but my order hasn't updated. It's still 'Unpaid, Unshipped, Expired'.

They are now sold out  :-\

So, this is a less efficient version of the S9?  They are taking a step back with this.

Same thing here, bought, paid immediately, still shows unpaid.... wft bitmain?

when i see on the site, t9 its more high hashrate than s9 batch 22 and its lower than s9 batch 23 and its more power consumption than s9 and it more power efficiency than s9. i think if i have more money, i will buy t9 because the hashrate is more big than s9 and its lower price than s9. but how long we need to be wait until the payment become verified like many members complain?

They've confirmed my order/payment via a support ticket however my order status still hasn't been updated.

Less efficient but cheaper MSRP. Doesn't make up for the fact that it's less efficient though. Like you said, a step back for sure but it's better than them not releasing anything tbh.

 Scam post, delete this shit please.

Looks like the last 2 batches offered on the Bitmain Chinese store were T9's and no S9's.  Maybe they are cutting over production of these miners to just T9's now?  Just thought it was worth noting... Interesting.

You better report it to moderator than to quote it.

It's 1450W +7% it's not +/-

That's 1550W! with the 7% factored in.

I'm sorry but this looks like bitmain trying to create a new product that increases profit margins to capitalize on the recent increases in BTC value.

The sad truth here is, people will probably buy this crap.

My guess here is they finally fixed the S9 problems and instead of continuing to post fake specs about the power usage and capability, they are going with actual specs this time. I don't own an S9 so this is just speculation based upon what I've read about people complaining about the S9.

Also if they did fix a design issue with the S9, owners would be clamoring for replacements. Bitmain Solution: Create the T9 and move away from the bad like Microsoft did with Windows 8.

When will next stock be available ? approximately 3-7 days. @Bitmain

all things being equal  the r4 at 7.5th and 916  could be  a better deal then the t9 at 1104  11.5th.

the r4 will use .1  watts
the t9 will use .126 watts

so 3 r4's = 22.5th  and        2748

and 2 t9's = 23th   and        2204  this is 544 usd difference  and shipping  makes is about 600 more for the r4's



So  I will pretend  they are both 23 th for math   ease

23th at .1 watts = 2300 watts

23th at .126 watts = 2900 watts


so 1 ibm 2980 psu runs all 3  r4's

and 1 ibm 2980  will be short for 2 t9's   so the r4's save back some of the 600 price difference in psu say 50

so 550 price difference

and you save 432 kwatts per month

600 watts per hour x 24 = 14.4 kwatts a day

at 10 cents  that is 43.20 usd per month

So  in about 1 year  43.20 x 12 = 518.40 

which means 3x R4 7.5th vs 2x T9 11.5 are close to a tie in value. 

4 assumptions  made are  :

1) nothing breaks
2) .126 watts per gh = T9
3) .100 watts per gh = R4
4)  10 cents  a kwatt


Many will say 10 cents a kwatt is too high  use 8 cents a kwatt   so after 16 months  they are pretty much equal

The real key is the true power used.

If the T9 does     .135 cents at the meter
and the R4 does  .100 cents at the meter


the r4 is cheaper after:

 9 months at 10 cents a kwatt
12 months at 8 cents  a kwatt

Are they trying to get rid of their B stock chips by creating another product?

This could very well be one of the reasons.

exactly what i suspect they are doing and keeping the final good quality design S9's for there own in house use

I came to the same basic conclusion Phil, but your math sealed it for me.  I missed the T9 flash sale and don't believe any more S9s will coming for a while.  I placed an order for an R4.  It will be my first.  Was temped to have it shipped to me.  But my electric is too high.  So it's heading to hosting with my other ones.
Thanks for the proof.

I have never brought a large quantity of miners from Bitmain. I'm a little apprehensive with a big order all purchased with my BitCoin.  :-\

I wouldn't worry.

I purchased mine almost the second they became available.

My status is now

Paid
Shipped
Valid

Tracking numbers received and there on there way :)

The point of the T9 is to trade a bit of efficiency for a more reliable machine.

As 16/14nm is pretty much the standard for the next few years it makes sense to buy a miner that is slightly less efficient but will run twice as long without problems. We all know the S9 has issues, and the release of this miner seems to support the fact that the s9 hardware is being run on the very edge of reliability to get the .10 spec, which in turn is causing a number of premature failures. It only takes one bad chip to take out an entire hashing board with the way the boards are designed.

Delete your quote of said shit please.

Can you back up this claim?

what's with the difference in fan speeds?

https://i.imgur.com/6IiddrD.jpg

The push fan is slower with a resistor in the feed wire.  This lowers back pressure from blowing too hard into the heat sinks.

Officially no. But I dont mind people not believing me, it makes it more fun to say 'I told you so' later on  ;)

When we are able to order?
I'm really confused!
after this time we can record our order: after 2300 hours (GMT+8) today (17 January 2017)??

In this way we must to wait about 95 days later for order?

They were available but are now sold out, you'll need to wait for the next batch to be released - mostly likely after CNY.

Looks like you missed the boat; they are sold out.

Back to my original question though; has any high leveled members made large orders from Bitmain with Coin only? At least 30 miners at once. No disrespect Cybermods but I would feel better with confirmation from a Vet who has forum trust established.

Do not hesitate to buy from Bitmain with BTC.  Despite their shortcomings, they are trustworthy to ship out goods.  Only a couple times did they ship miners "significantly" late, as in a month or so.

Hello guys
Does bitmain shop are still stock for T9?!
User @moneroorq send me message that contains a link were and he claims that it can still be order.
but when I go to the site is shown sold out ???
Is he honest?
http://uupload.ir/files/aahk_screenshot_20170119-153004.png (http://uupload.ir/)

He's trying to rip you off, you will see the URL his link takes you to isn't bitmain.com

While that may be true, do not trust a new account to take care of you, heed the warning

Probably negative presure. Less air comes in more air out.

but are the same fans models right? who controls the speed? is any order you should connect the fans on the main board?

Unsure how sharing the status of my purchase requires trust but whatever floats your boat..

keep calm and mine on

Does anyone know when will be availabe the stock again? Or it could be in the midnight?

bitmain  is going on vacation  for 1 week  say Jan 26th to Feb 2nd.

you can look here  every 30 minutes


https://shop.bitmain.com/main.htm?lang=en


If you get lucky sometimes someone  cancels

Most likely you won't see them on sale for a month.

you can go here

buy used

https://bitcointalk.org/index.php?board=75.0


I do escrow service.

Most batches have been released for sale at 23:00 Beijing time (GMT +8) and friday has been a quite frequent day.

 So, Do you mean It could be in stock today?

They may.

But you need to check every 1/2 hour for cancelled sales for the next day or two.

As this could happen.

Most likely you won't see anything and will need to wait until mid February

I can NOT believe their garbage left over stock sold out that fast.

My god you people are worse then nintendo fan boys

What ever they put up and stick their name on you scoop up like drug addicts.

Can't wait to see the failure rate on these!

Maybe actually decided to make reliable miner when oposition starts to show up.

There was no need to design for reliabilty previously with the rapid chip improvements, now that chip efficiency gains are slowing to match Moores law it makes sense to improve reliability and minimize customer support costs.

Still, trading efficiency and power for reliability? Farther down the road that isn't going to work. It's just a cash grab for them and we have no idea if that's true or not, if these miners are actually more reliable. Hasn't ever happened much in the past and if anything their reliabilty has gone downhill since the S1.

As far as I can see Bitmain doesn't have any significant IP (patents etc), so I would hope as bitcoin continues to be adopted that eventually more chip foundries and manufacturers will get in the game and drive up competition, which will mean better products at better costs.

Actually its gone the other way, a couple of years ago there were many more chip manufacturers. There are still 3 or 4 still going, but bitmain has the most efficient chip at the moment.

Think ill wait for sidehack to get his teeth into one of these before I make a decision.

Saying that. I'm in the market for some new miners.

Decisions...Decisions

I'm waiting and running my KNC Titan 'mules' into the dirt. Likely at this rate with
3200mh (9 Titans) they will be doorstops at the diff rate increase. By July at this rate.

Unfortunately, I think
Bitmain is gonna run these out like toasters. In the same manner as their btc miners. Likely
down to 3c kWh and below, to ROI I mean.  Thus asserting dominance in scrypt for equip and data halls like they have done in btc world. It seems pretty obvious.

More chip manufacturers we may see.

More Foundries to produce their chips -- not going to happen. Aside from fabs ran by Intel and IBM there is only TSMC, Samsung, and Global Foundries that are capable of producing 16/14nm (and eventually smaller node) chips. Samsung is largely producing for their own products with so far BW chips being the only exception. That leaves only TSMC and GloFo to run boutique chips like mining ASICS so end of story there.

My T9's just arrived, I really hope these go better than my R4's.

Good luck and post results

Let us know how it runs/stats. 

T9's have been nice and stable for the past few hours.

http://imgur.com/a/4B3p3

Yee looks nice. Good luck with miner.

he should have some today

My T9s arrived earlier today and are all up and running nicely. No problems to report so far.

sat on the shelf beside my S9 with its 76d3h38m32s uptime :)

Il update if anything changes.

Thanks for the Update.  Does anyone else have any early experiences?

The 3 T9 units now have 8 hours run-time on them. All performing at or a little over stated hash-rate.

Temps appear to be nice and stable. Fan noise on par with the S9 i have beside them.

So far so good.

I have been running 10 X T9's for 7 hours now.  Cool and stable.

On another note.  I have already lost 4/10 R4's from my friday delivery.  Awesome.

Bitmain said they will cover shipping on them though.  We will see how that works.

sick miner as always!

Here's a video I made today showing comparison of T-9 11.5 vs. S-9 12.0 variable frequency power draw at the wall. Uses more power, but runs cooler.

At 210 VAC
T-9 uses 1352 W, hashes at 11.5, highest chip temp 80C

S-9 uses 1329 W, hashes at 12.0, highest chip temp 94C

https://www.youtube.com/watch?v=yHJzo7A312c

Thanks for the video Jack.  How strange the S9 is using so much more power than the stated specs on the web site.  I think they quoted something like 1079w for the 12th S9 so that is significantly above the spec. 

Really looks like the T9 may be a winner then just based on the cooler temps and the power use looks like it isn't as bad as was stated in the spec for that unit.  Good to know!  The T9 may turn out to be a good unit!  Please keep us posted.

Well, in the first video I made I compared it to a 550 fixed frequency S-9 at 11.85 TH. The older 550 speed S-9 used only 1178 watts. I think when Bitmain changed to variable frequency they didn't update the specs on the S-9

whats is you room temp ?
and S9 batch ?
because latest batches have less temp than earlier one

I have just watched this miner. I feel very impressive with this batch of antminer.
I will buy it in next month after I got my salary.

It was the S9 batch 16 available in about November 2016. Room temp was about 60 deg F

yup really looks like realiabilty is finally fixed. Instea dof trying to push to limits and then dying like flies

Ah the time frames of Youth...
A few miners with a few days of run time on them does not equal better reliability than a s9. Most folks have zero trouble with the s9's at the start (and minimal issues during its lifetime). Out of the 16 s9's starting from batch-1 that I have, only 2 bad boards to date.

At least give them a week, preferably > a month and THEN make that call... Now better than the latest R4's -- based on my 1 bad out of 3, so far I'll give ya that one.

Just lit up a pair of T9 on DPS1200 PSUs. Meter estimates 2850W for the pair and one-hour reading of 23.43TH between 'em for an average of 0.121J/GH.

T9's and R4's have been since Friday/Monday! Here are a few pics of them :) http://imgur.com/a/vYxSj (http://imgur.com/a/vYxSj)

Very clean and nice looking setup!

Looks great. My question is why would you buy R4's for a datacenter installation where noise is not an issue? The cost per gh on the R4 is 30% higher than on an S9.

At the time of purchasing the R4 was the only miner in stock. we picked up 10 of the 7.5's and 5 of the 8.7's. We were just itching to get some more miners/hashrate since before we bought these it had been roughly a month and a half since our last purchase.

I received a T9 with what seems to be a defective fan. It starts hashing and soon it overheats. One of the fans does not go above 1900rpm.

o boy and that is biggest ASIC manufacturer in world. If that comapny would be in EU or USA. it would have been shut down alredy, assets stripped, property confiscated.

Looking nice!

T9s installed Saturday.  So far so good.

My 3 T9s have been running 24/7 since the 23rd. No problems to report.

Through week #1 today. So far so good. I wish i could change frequencies and fan speeds though.

Only complain was a "slow" fan wich was causing a miner to overheat. I had spare fans from a few S7 lying around, so problem was quickly fixed.

I think this forum topic is meeting its demise.

Funny, the tread is pretty dead because there aren't tons of us complaining about the high failure rate of our new miner (S9 or R4 thread anyone?)

Much like at a dinner table, if there's not a lot of talking the food is good!

I agree it seems like the T9 thread has been very quiet which really does imply that it addresses the S9/R4 issues.  No one complaining yet so this is a good sign.  But then again when the S9 first started shipping people were happy too. 

So maybe another 30 days and we should probably have a good idea if there is going to be any fallout. 

my S9's started failing 80 days in (10 days short of the warranty expiring), got a few boards repaired under warranty. At least now they come with 180 days warranty.

I wish I had one of those cricket chirping sounds for this forum.  haha

No issues to report from my 3 T9s or my B14 S9  :)

https://i.imgur.com/i3PqSh5l.jpg

So the T9's were announced Jan 17th, here we are Feb 17th and nobody is shouting to tar and feather Bitmain over the T9's yet...

Hmmm, what kind of crypto thread is this???? No drama, nobody threatening violence, boycotts, or using strong language against Bitmain... Where is the fun in that???  ROFL

T9 - 11.5 TH/s appeared on shelf now but in sold out status. Did I miss anything today/yesterday?! ???

It was in stock for about an hour. Keep an eye on it if you're interested, they often go back in stock briefly if orders aren't paid on time (within 1 hour).

Thank you for the confirmation. I just can't imagine that they don't even bother making announcements nowadays :-[

available again..

Ya know what? As much as it kills me to say it but so far I am pleased as punch with the Avalon's I've picked up and gotta say -- I'll pass for now. This is coming from someone who got his 1st s1 on March 14, 2014 and have gotten >95 Ants of all flavors since then so that is not easy to say. Reason: Quality of the s9 and R4 miners.

My s9's from batch-1 through 22 so far have been great as have 2 of the r4's but my 3rd R4 lost a board after just 24hrs. Reports abound of s9 and R4 issues and truth be told, Bitmain blew it with those miners.

Is the T9 better/more reliable? Maybe, but for now Bitmain has lost their monopoly and I for one am glad for it.

I'm with you.  I've been through the paces and experiences with the hardware (GPUs, ASICMiner, BitFury, BFL, Bitmain, etc) since early 2013.  I've also had my bad experiences with Bitmain.  In my opinion, however, the T9 is still be best deal today at around $108/TH (0.126 J/GHs).  The S9 13TH is around around $122/TH (0.098 J/GHs).  The newest Avalon 741, however, is very competitive at $112/TH (0.157 J/GHs).  Not much of a difference in the short run...  However, in quantity and over the long haul the cost diff can easily add up.  Who knows,  I may also jump to Canaan.  Time will tell.

I'm with ya there. I've bought mostly bitmain gear in the past, starting with their stick miners. But my last two miners, an R4 batch 6 and the Feb 28th S9 both have had bad boards out of the box. I was thinking of purchasing another miner, but skipped the latest T9 offering. I'll probably go with the newest Avalon, as soon as I see how I like Oregon Mines for a hosting service.

My T9's are running like champs. I was able to order a few more this last time. Stayed away from the S9's.

It will be interesting to see how they handle the heat this summer in Atlanta.

It's been a warmer than average year so far so hopefully it won't get too hot, I know it was pretty warm in South Carolina last year, nothing unbearable for my miners but warmer than I'd like for optimal performance. Your miners might get louder and spin faster assuming they run pwm but that should be it.

I have 5 T9s and they are doing great so far. Mining for a week now

id LOVE to get one of these but i cant pull 1500 watts from my outlet :(

its too bad that you cant underclock them.

Wow, this is the most power hungry Antminer so far.

Great price but at 1576w + 7% is not intended for the home miner. We have the space, power, and proper cooling here at ColoHub data center. Our all inclusive monthly hosting price for this unit is $92. www.btcmeqc.com (http://www.btcmeqc.com)

Because people are Sheep
Bitmain is the only game in town and 90% of their customers are too dense to understand how it works.
They see the newest and jump. with no research.

Bitmain doesn't NEED to try, they have ZERO competition and sell out each time.

WHY would they care or try?

It is not bitmains fault that people cant understand this is industrial equipment meant for a datacenter and not for home use. I see so much blame going on because people cant run them at home. Stop being so ignorant and just accept these are meant for datacenters not bedrooms.

I thought the point of the T9 was that you could use it at home because they made it very quiet? Or is that a different miner they released?

They don't want you to mine at home because doing so would decentralize the system. They want to own every hashing power there is so they can fuck up bitcoin and can start their own shit coin. BTU.

Fuck bitmain.

You should really not spread this level of stupidity by posting it on public forums. Bitmain is the ONLY hardware producer that DOES produce a home miner, the R4. No other company has even attempted a home version of a miner with 14/16nm tech. Go put your tinfoil hat back on and look for conspiracies elsewhere please.

Actually Ebit E9 miner should not be that bad to use at home.

Also there is Hotmine (en.hotmine.io (http://en.hotmine.io)), who offers upgrade kit for old Antminers and also full package miners for those with no good old Antminer.
Hotmine X5 boards should be quite reasonable for home use with power consumption about ~500W.
I'm currently in talks with them about buying one X5 upgrade kit for my old Antminer S1.
I will also need to find Beaglebone Black board.
I'm planning to do a quick review/how-to if everything goes ok.

Hopefully you can get one. I would love to hear what you think of these.

The E9 is good on power consumption for a home use, but with only one fan they are noisy. About the same as an s7 at full speed.

Ok, I stand corrected, so no Ebit E9 for home mining.

It's R4. But as with all Bitmain hardware these are dying like crazy

It is Bitmains fault if they ship DOA miners or with dead boards. Or if boards die soonish after they start working. Any company that would make this kind of equipment outside of crypto would be defeunct and sued in first month with this kind of shit.

Does anyone else find it odd that they are recommending the APW3 as the power supply for this batch?

At 1576w + 7%, I would think it would be too much for a 1600W power supply to run long term.

Yes I was wondering about that myself!

I wonder what could be so different in the design of the S9 and T9 that the T9 so much more inefficient  ???

Does Bitmain ship To istanbul/Turkey ?

They definitely don't want you overclocking them that's for sure.

The T9 has less chips and they run at a higher voltage internally to make up the hash rate. That is where you lose efficiency and gain stability.

Look at sidehacks S7 undervolt project for parallels. If you have enough mining boards available you can find s7 boards that will hash at .22 but the average board becomes very unstable at those voltage and clock speeds. The best I was able to get out of undervolted s7s on average was about .25 stable over the course of days and weeks. The S9s are similar in that bitmain sets the voltage on the chips as low as possible to hit the efficiency rating they claim but it causes major instability and premature failure of the hashing boards.

How many btc it can mine per month?

 I believe Bitmain specifies that as 1576w "at the wall" using one of their own power supplies - the actual MINER usage would be closer to 1470 watts.

 A high-quality 1600 watt PS should be able to handle it, though it would be a bit marginal.
 SERVER power supplies are routinely specified for 24/7 usage capasity, most consumer-grade are not - though the higher-end stuff from EVGA and Seasonic tends to be reliable at very close to ther rated capasity in 24/7 service.

 A little over 0.006 a day right now, so about under .2 a month 'till difficulty goes up again.

Then its better to buy btc right away instead of mining.

How home miners are still profitable?

Unless you and your family are deaf, the s9 and T9 are NOT 'home miners'...
Definitely made for industrial/commercial use.

wow sort of feel sorry for the people who paid 200$ more last week..

Higher hashrate

The 11.5's are cheaper per TH/s @ $91.8 per TH/s vs $96.4 per TH/s for the 12.5 - seems like a better deal to me.

It's how bitmain always prices their kit based on hashrate. I didn't say it made financial sense :)

Well since I'm running out of s7's to replace with s9's or Avalons ( I *do* have a power limit) I broke down and decided to order a T9 for the farm at work. Ya know, just to round out me having had at least 1 of all Ants except for the s5+ (R1 and U3 don't count). :P

On a per-THs basis, is a fair bit cheaper than the A741's and on par for power eff. Question still to be seen is, are the T9 as reliable as the Avalons? Only time will tell....

I don't trust Bitmain in the slightest, no new product they bring out will overcome their very poor business ethics.

Check out my experience here: https://bitcointalk.org/index.php?topic=1836179.new#new (https://bitcointalk.org/index.php?topic=1836179.new#new)

Ja your experience with them truly sucks. Thankfully most people fair much better.

The T9 on order will make it 82 Ants I've gotten since 2014 and to date exactly 4 boards failed. 1 from an old s7, 1 from a R4 batch-6 failed after 24hrs and  2 s9 boards 1 a batch 1 the other batch 12, both failed Nov-Dec last year.

It's good to know they aren't ripping everyone off. Although I am very hesitant to believe that I would be among the minority who have had such experiences. Based on how I was treated, they do seem to have a certain amount of contempt for their customers, and this could translate into a low quality product.  

I'd like to know who else has had similar horror stories...

I have over 100 T9s running with zero failures so far. They clown on the S9 for reliability. IMO the efficiency trade-off is well worth it since its likely an S9 wont run problem free until you reach ROI and it looks like these T9s will.

I wonder whether the efficiency trade-off translates into selling used equipment from their own mine. The second hand equipment they gave me in replacement of my faulty boards was definitely from their mine, but I wonder if they are selling second hand machines as new.

How long until you reach your ROI do you think? And how long have you been running your T9's?

100% , they are the rock to the S9.

Even in China, selling used anything as New violates the law. Sure that only really works for Chinese Nationals as far as prosecuting goes but it IS excellent grounds for FTC to bar imports so. Bottom line is no they don't/can't. For warranty replacement them using reworked/repaired boards is allowed and in fact is very commonplace throughout most electronics industries.

As for getting dirty/dusty miners... Ever been to any large city in Asia? ;) When it's dry they are often very dusty places. The miners are typically all burned in for at least 72hrs in open buildings. Dry out of the rain yes but sucking all that city air well you get the picture.

 

Just because it's law does not mean they adhere to it, I know many Chinese companies that use bitcoin to evade their taxes, so the law would appear to be relative in many cases. But either way, they are either selling a faulty product knowing that their customers are unlikely to even reach ROI, which is all kinds of wrong. Or they are selling second hand equipment from their own mine despite the law. I had around one third of my boards die within 2 weeks of operations, so one of my 2 scenarios is true.

And as for replacing warranty parts with second hand equipment, I have never received second hand equipment in replacement for broken electronic equipment. Even if it does happen a lot in Asia, it's still a bad practice and shows contempt towards the customer.

Any machines I have purchased from bitmain used were clearly communicated to me prior to purchase. I have never received used hardware that was sold new. I do apologize for not being able to answer but I do not disclose financial information on this forum. I have multiple batches so there is no specific answer for your final question.

IMHO it is your first one: To squeeze out the highest possible yield of the 16nm chips Bitmain has seriously widened the QA window for what are "usable" vs good vs Prime chips.

Looking at speed/hash rate spread between boards I'd guess at least 3 levels are used for binning chips to be used when populating boards targeted for highest efficiency miners (s9/R4). Hopefully humorous example would be 'meh', good to very good, and finally best. Given the typ yield of 16nm that makes for probably 2-3x more 'meh' to good (say >80% of cores work) chips than best (>90% cores work at full speed) grade so....

Tie that with lapses in board assembly quality checks... On the 2 s9 boards I had fail the placement and soldering of the VRM was -- horrible. Frankly, surprised it passed at all considering the module was rotated enough to be just literally a hair breadth away from shorting right off the bat. How/why that wasn't caught by an inspection camera, who knows...

With the T9 hopefully their sacrificing eff by pushing the Vcore higher is what results in otherwise 'good' grade chips performing as very-good or better. As to the board assembly - who knows...

Your assessment is plausible, and if its true, then Bitmain has turned into the MacDonald's of the Crypto industry, willing to sacrifice quality for profit. I'm sure they will start to feel the results of this approach soon if they keep it up. I guess time will tell how their T9's go, but I for sure will not be doing any more business with them.

It's nearly impossible to run into profit with this thing, ROI for the unit cost is nearly 1 year, not yet count for rents, air-con, electricity and labor cost.

For you maybe. If so, don't buy it
For folks like me, it and its brethren do pay for themselves and generate profit in reasonable time just fine.

new S9 batch is coming...
https://twitter.com/BITMAINtech/status/849929336064942081
someone already know the unit price?

Bitcoin mining has become too centralized because of what you mention, mainly because the initial investment is pretty significant, for unit price and setup costs. Bitmain is too interested in profits to give smaller miners a chance at getting into the game. Plus the T9's 11.5TH is nowhere near powerful or efficient enough to give substantial enough returns for the price they ask. But running costs can be reduced if you setup in the right environment, as well as labor if you have the skills to do most of the work yourself. I think Bitmain just serves the big miners now, so if you're a small miner best to look into other crypto's to mine.

The entire bitcoin ASIC industry serves the big miners. Ebit, BW, and Bitfury dont even sell individual units.

Thats what altcoins are for.

Back on topic here, Bitmain is shipping the T9 'ship April-10' orders now. Got my UPS shipping notice yesterday :)

EDIT: 8:00p, just checked UPS and the miner has already left Alaska! Should be here Friday.
I haven't seen a miner move that fast in months!

Does bulk order would be a lot cheaper?

Am I imagining things or did Bitmain just jack up the price of the T9 & S9?

When I looked this morning, I swear the newest batch shipping April 15th was $1050, but now it's $1150, and the S9 was $1156, but now it's $1296.

I guess so... But you would have to send a representative to negotiate with them to get the best deal, otherwise they will just refer you to their website. Perhaps a big miner might give a better answer on this...

The T9 batch thats available now for $1150 is 12.5TH/s. The one sold for $1050 was 11.5TH/s

So how do I enable ASICBOOST on these ?

Nobody will tell you...  >:(

Bitmain enables it....the extra hashrate is sent directly to their pool....I bet  :D

Back on topic, new T9 miner arrived today. As expected so far running perfect @ 11.7THs :)

it saves power. Thats why their miners are so efficent.

https://www.reddit.com/r/Bitcoin/comments/63yo27/some_circumstantial_evidence_supporting_the_claim/dfy5o65/

It's good to note no major pools really accept ASICBOOST, excluding Bitmain, yet, it'll probably change with time. I'm mostly interested to know the full capabilities of the once thought to be obsolete S7.

Who said the S7s are obsolete?

For most people with ten-cent electricity, it's generally not worth running anymore as the prices you can buy them at today are too high to justify buying. They're just fine if you have some right now but they'll become the next S5s in a few months. I noted once as it's possible ASICboost could give a little boost to the now older S7.

Well, so far so happy with how my 1st T9 is performing I decided to get another with the 'before April 15' ship date to upgrade the main farm.

This time will be kind of a sad occasion as I will be retiring my one of my s7b1's. <sniff> That sucka has been solid as a rock for the past years holding a steady 5.3-5.5THs as reported on Kano but since I have a power budget finally time to take advantage of the T9's over 2x speed at the cost of only ~100w more power.

The hardware is not obsolete just because some people dont meet the requirements to run it profitably. You dont call a 2 year old car obsolete just because there are no paved roads where you live to drive it on. At $0.03 power they still profit about $58/mo after paying for power.


As far as the ASICBOOST goes does anyone know if it is even baked into the BM1385+ chip? As far as I understand the whitepaper for asicboost came out early 2016 and bitmain had been producing s7's since summer of 2015 which would lead me to believe there is nothing in the hardware of the S7 as far as ASICBOOST goes.

what i read from asicboost was that it would require hw support on both the pool and rigs. Even if they have built it into the miner chips, the pool has to support asicboost work distribution too. it would not work otherwise.

WOW, that is ALOT of Wattage!  It does not make sense Hash/Watt...   as compared to the S9.

You can have a power efficient miner....or you can have a reliable miner with a real chance at reaching ROI before falling apart.

they can make both, they choose not to..

besides, these T9s have no chance to make roi at these prices.. even with zero electricity costs you are 12-14 months away.. thats if the difficulty doesnt go up, which it will.. you are probably realistically looking at 18-22 months roi.

only one making money is bitmain.

Let me guess: Bet you don't own any miners do ya?

Same was said of the s2, s3, s4, et al when they came out. I paid a helluva lot more $$ for them and guess what? All paid for themselves and more to the point, paid for upgrading/expansion. Currently bouncing around 230THs (I'm Fuzzy on Kano), all paid for from farm income...

Got a T9 on it's way as we type that will replace a s7 batch-1 I'm finally retiring. Still is running a steady trouble-free 5.3-5.6THs. Checked and see that the s7 batch-1 cost $1,823 + shipping. Despite that it was long ago paid for. Still makes money but I have a power budget to stay under while expanding the farms hash rate... Depending on how ya look at it, yesterdays 4-block run had the farm in just that one day pay for nearly 1/2 the cost of the new T9 coming which cost BTC0.996 inc UPS shipping ;)

How do you know what batch or view batch details ? I have looked at my invoices on Bitmain and can see no reference to batch number ?

Cheers

What happened to your R4's; i'm looking for a QUITE but high hashrate miner, S7 and S9 are to loud.

Seems there's NOTHING out there !!

QUIET

There is nothing out there that is comparably high hashrate and quiet. Can you think of any sports cars with high power that are quiet? Noise is a trade-off when needing to dissipate a lot of heat.

Check out the stick-miner threads if you want high efficiency, quiet miners.

I did not have such luck. I have 2x T9. One stopped working properly after a few days. After warranty repair is ok. But with S9 I had no problem. But this is a small statistics sample.

Yes, it's quite because somebody doesn't want to buy this project and it's very long to get a profit and ROI. They almost invest money to get GPU Farms to mine ETH and DASH, ZEC... it's more profitable than ASIC Miners.

I have a few spares from old s7's and cards etc, might try flashing it with S7-LN firmware and see if i can run 2 cards and make something to hold a psu on top.

Considering the s7 family uses a different ASIC chip and CPU I highly doubt the T9 will run and you very well might brick it...

I was going to try and make a S7-LN from old S7 parts, not the T9.

Well this is a T9 thread so...

Id rather have the r4.

Due to multiple failure of a hash board on my R4B4, I have been offered a 'new' T9 for exchange of the stumbling R4.  I'm guessing I'll probably go with it - if I have it warranty repaired again there's no reason to think it won't do the same once again and drop to 1/2 speed after a short time.
Not thrilled with the large decrease in efficiency, but fully running less efficiently is better than half running more efficiently, if that makes sense...
A big Harrumph either way!  :P

I run my 1 and ½ r4s  and never went for any repairs.

the one with 1 dead board has run fine since dec
the one with a loud fan has run fine since jan.

I will just let them run till they drop.

I would go for a t9  but I am making money hand over fist mining Zec with gpus.

So I won't expand my 60th of sha 256.

I make more money with 6600h of zec and will soon expand to 8000h of zec.

If you analyze the issue why this has happened  the fault is 20 billion usd worth of BTC  is mined sitting in peoples wallet's

you don't need to mine anymore  just get some one with early mined cheap btc to use thier password to buy your ZEC or your ETH.

Think of the guy sitting on 100,000 btc mined at  1usd  each. He has 125 million usd in coin  He can diversify into ZEC  and ETH VERY EASY.  As he may not want to  convert to fiat.  So he  slowly buys ZEC and ETH  looking to have an eventual ratio of 33% of each coin in terms of fiat.   which would be about 41.6 million in fiat


or
 33,000 BTC
594,286 ZEC
832,000 ETH

someone is propping up ZEC and ETH  BY PURCHASING the two coins with BTC and fiat.

More btc then fiat.   So as long as this occurs  I won't buy any sha 256 gear. 

the t9 the s9 or the s4  = no no no
avalon 741 = no no no

I will only buy sha 356 gear from sidehack as I like his gear.

I will continue a slow expansion of gpu mining for the moment.

Maybe check www.antbleed.com to patch your vulnerable miners.

Any one seen hash rates displayed like below? Miner still appears to be hashing at it's intended rate, the pool shows the same - I'm just concerned as it looks a little odd and none of my other T9's display like this.

https://i.imgur.com/Bfcz9JZ.png

With the R4s such behavior is a first sign of imminent failure. But maybe its nothing.

Heh heh...
6 days after I paid for one of the latest T9's the tx just got confirmed this morning and Bitmain acknowledged it, changed order to valid/paid. Question is, any left to be shipped... ?

Wow,most tx take about 3-6 hrs for me.....Corp BTC miners are gettin greedy,with all the hashrate you'd think maybe 30 mins or less.........  ::)

Most are quite fast for me in a few hours as well. My prev longest was 2 days. Maybe Blockchain.info had a brain fart as a consolidation transfer I did about an hour after the Bitmain order also took the 6 days to confirm as well.

2-3 hrs is not fast,I remember tx times of less than 20 minutes...not THAT long ago...methinks there is something to the "selective mining of transactions"  :(

Nah,that's impossible........................

Anyone else notice mention of a "T9+" on Bitmain's "fix the exploit firmware" page?

 I wonder if they're going to do a S5+ style "big" miner based on the T9....

Not sure if a s9 board will work in the T9, for 1 they are a different length. Be sure to ask them if it can be used.
I do see they also now carry spare T9 boards however. That what you meant? ;)

Bitmain Warranty of course does PAID repairs of hash boards and normally all they need is the board -- not the entire miner like the factory does. If you send the board in, ask about mining comp (equal to the boards hash rate) while they have the board.

How loud is the T9 compared to the S3? Is a T9 a better choice for home mining than an R4?  It seems to be a little more trouble free than the S9 - or is that an illusion?  Will BITMAIN make any more of this family available. Any rumor on how close the next generation is? Also looking at the 741. But that is another thread.

I retired my S3s last year and got out of mining for a while. Now I am considering investing some of my BTC in a new mining rig. I'm in a 2 bedroom apartment with electricity included and I have a 20 amp circuit I can put a miner on. Not going to quit my day job, but my little pile of BTC from my last effort looks pretty darn good now.

TIA

To answer your question, ONLY the R4 is on par with an s3 regarding noise.
ALL other modern miners such as the Avalons, Ebang, and Hotmine are LOUD. And NO they cannot be changed to make quiet.

Thank you. I'll have to think carefully about a loud miner.  Those S3s were so wonderful.

So far S9s were great, some boards need maintenance sometimes, but it's worth it.
I ordered couple T9-s, the new shipping policy makes it damn hard to somehow overcome double shipping taxes with whole unit and I will discuss it later.
One of my T9-s sometimes drops to 8Th which means one of the board is malfunctioning, after restarting the miner it reaches it's maximum, but I have to do it daily. what is the caus of this and is there a chance that I can check/repair the miner myself? IN case of S9 I just have to take the board send to Bitmain and get it back, but in case of T9 sending whole unit costs me roughly one month income of it, so every time one board is damaged on T9 I'm loosing month of profit + the time it needs to ship it to China and back. (The only way to send them from Republic of Georgia to China with EMS costs about 300$ when one board is only 50$, DHL/UPS charges three times more)

I was wondering how everyone else's T9 are doing?  I have 4 and they were all working great until about 2 weeks ago when an IO board on one of them went out.  Bitmain didn't reply to any of my support request until yesterday which was by surprise 181 days after shipping!  Anyhow I asked if I can buy a new board off of them as I figured it would be faster than going through warranty anyhow and they said they're out of stock and will let me know when they'll come back into stock.  Does anybody have a T9 which they're selling parts out of?  If so I'll be willing to buy your IO board from you.

How did you ensure it was IO board issues? I have 5 T9's that were running fine just until the recent 2 months. they seemed to be up with power but there's nothing connecting on the pool side.

My miners are hosted and the below is the message they sent.  They were nice enough to loan me a S9 IO board, but it's only able to hash 2 of the 3 of the boards and I'm sure they'll want their IO board back sooner or later.

After testing different quite a lot of different issues, I've concluded that your IO board is defective. I've tested the following:
Factory reset
New power supply
Tried to remove one or more hashboards
Used an S9 IO boards and found all hashboards are working

Technically, because you reported the fault before 180 days, you should still have the right for warranty.
You have no influence for they to answer late, so it is only right that you get your warranty repair.

One of my T9s does the same. Been like this for a few months now but hashes fine and temps are fine so I have left it alone.

Hi all. I am a newbie here as well as to Bitcoin world. So my question might sound stupid... anyway, I've heard that when the new Antminer comes, the old ones are not working to their full effect, or mining not as profitable as they were previously. So for example, we have now antminer S9 which let's is making a 100$ profit per month, when T9 will come would be S9 less effective just only because there is a new machine out there? So any ideas? Sorry for my bad English. Thanks in advance!!!

If and when a new batch is released, the network hashrate increases due to miners turning on and hashing away, decreasing block times and increasing difficulty. It’s not just a new miner coming out by itself that profitability begins to instantly decrease but more a matter of difficulty too.

The S9 and T9 are brothers. Same basic design, same chips. Only difference is that the T9 was built better and runs at a higher chip voltage - that makes the T9 less power efficient but also make it more stable. It has been over 1 year since Bitmain made (very few) T9 and I doubt they will ever make more.

Man bitmain really knows how to go for the jugular. Pangolin releases their miners at a flop price of $2350 to ship out in 7 days and its just sitting on their site. Now bitmain sends an email that they are releasing T9+ tonight with a 10 day shipment window. Any speculation on price here?

If it is priced around 1200 usd, I will buy, but if it is much more than that, I will probably pass.

With the limit of 2 per person I have as feeling this will be a good price. But I could be wrong...

I hope it's better than 24900 Yuan price that they had it for on the Chinese site. At almost $4000, there's no way I would buy one.

Guys! Antminer T3 just launched for sale.
https://shop.bitmain.com/productDetail.htm?pid=00020180129100354816a62X9dGp0668

T9+, so 10.5 TH/s for 2100 plus shipping plus PSU. No thanks...

It's been several minutes and not sold out. I hope this recent BTC dip at the same time the T9+ went up for sale and the lack of interest push Bitmain to lower their prices.

LOL I know, but I have to stay optimistic :)

Looks like they lasted 1 hour 20 minutes.

Back in stock now and they reset the 2/person limit so that one can purchase 2 additional units.

I have BCH ready  don't know if I should pull trigger.

it is 1.32 bch with the shipping

ships fast  10 days

about .14 watts a gh.

I was able to buy six with some different bitmain logins I had. For the reliability it’s a no brainer to supplement my s9 farm. People balk at this price but snatch up Avalons immediately. When these are proven to be much more reliable than s9s, I don’t get it....

they simply hate bitmain.

My issue with it is  they delayed my Dec s-9  for 26 days  and gave me no coupon.

They did it to a lot of us.  Would be an easy purchase to make if I had  gotten compensation for that delayed order.

This unit's price is okay  but not great  about 2100 usd

It nets me 202-214 a month  that is a 10 month or more roi

frankly my gpus have been better.

most likely I will stick with them

If these were in the $16-1800.00 range I'd purchase, but by the time you add a 105.00 PSU, 200 or so shipping and 50.00 customs to that 2100 no thanks.

It's not a horrible deal, but I feel that they will be adjusting their prices soon. No real evidence, just my feeling.

Do you always get dinged for customs? I don’t have it happen to me often when I use DHL. When I use UPS I do. Also I don’t buy bitmains psus as I source hp 1200w server power supplies for $30/each.

I've been using UPS because I have an account with them. Interesting on DHL, I'll have to try that next time, but yes each time with UPS it's been around $50 for the miner nothing on the PSUs.

Are you making your own breakout boards? Even at $30 each that's still 60$ plus breakout boards. $105 just seemed to be a better deal. But I am open to creative solutions :)

No I am buying the cheap breakout boards on eBay for $10 and bulk pcie cables through my business. I am all in $51 per psu. 3 psus run two s9s...these psus are 94% efficiency over bitmains 93%

Gotcha, but you need 2 right? So you're at $102.00. Good to know!

Edited my post after you responded. 3 psus for 2 s9s.

I am really surprised people are buying these. They should be called the T9-

T9 - 11.5th - 171 chips - 1450w - 0.126 j/gh
T9+ 10.5th - 162 chips - 1520w - 0.144 j/gh

It is worse in every way.

Gotcha, thank you.

Also, LOL

Return just drop again past 24 hours. So T9 is competing against S9 and S9 is far more efficient in energy consumption.

Seams to be a policy to answer emails/tickets AFTER the warranty is out, saying "sorry, we can't help you".

It is annoying.

wavvv T9 came back i can't believe this.
What batch are those. Maybe Bitmain selling from their own miner used and claim new who knows.????

ROI dead bitmain
diffuclty goes crazy up and btc today dive under 10k
bye bye ROI
even S9 drop down under $10 after a long time period shit getting sucks

yep.... still available for sometime those T9.... USD 2K for 10TH/s at this moment is too much... passing

s9's break a lot

t9's don't break much at all


that said I did not pay  for the one I ordered yesterday.  fuck it.

My dec s9 order had a 22 day delay in shipping.

That was more then 325 in earnings taken from me.

Now to be fair they shipped my Jan order early so I gained maybe 400 on that for a net gain of 75 usd.

I know of more then ten other dec orders that were delayed more then 20 days not one person has posted that they were given a coupon for the delays.

I feel that the t9 may not ship as promised and I would be out more in mining income.

So I am forced to just stick with my gpus.

Jika saya ingin barang itu, saya harus menghubungi siapa pak, karena saya ingin membelinya jika harganya sesuai dengan uang yang saya miliki.

crypto is so cheap across thi board Im really suprised to see people buying new heaters ??!
for $2100 you couks buy a whole bunch of altcoins and just wait a few months for a double or tripple and thats just getting back to early jan prices.

Same with the A3 , $980 would buy 40k sia , which an A3 in march mining even 100 sia a day would take a year to mine.

I swearz somtimes ppl here make no sense.  Lol

Not that cheap.  But yeah some ASICS it makes no real sense to buy.  One can always just mine and accumulate without effort, then sell at the next big pump. 
Anyways a T9+ ? for 2000usd...please.  They need to adjust to previous prices..before they doubled ?  And the next generation of miners is probably sooner than we think too.

You guys should really use the other thread to talk about the T9+.

T9  = 171 hash chips
T9+ = 162 hash chips

Bitmain trying to convince us that less is more :)

The T9+ are still available on Bitmain for $2k. I was going to buy one last night, but their website didn't work & I couldn't use my coupon. Lucky for me because the ROI went from 9 months to 21 months overnight and looks to never break even with bitcoin heading below 8k.

id not pay more that $800 for a t9 and no more that 1400 for a bimain can get wacked

I need a new space heater for my basement.  I am considering this T9 for that reason and that reason alone.  I hate Bitmain, but I have several coupons; the thing is for the coupons, I have 5 coupons but for some reason they are olnly letting me use the 50$ coupon, not the several for 125$, and they will not allow multiple coupons on a single order.  This company is really horrible.  I can't wait until new or different companies incorporate the Samsung chips and create competition.  If I could ROI in less than a year I would bite the bullet for this but it does not look like a possibility at this time.  The only thing that is good is that it looks like Bitmain is shipping this T9 within 10 days.   

Someone on eBay trying to offload a bunch of T9+ at $4100. He's gonna be stuck with them for awhile even if he comes down to Bitmain's $2k price. ROI is not possible now. Even the S9 will take about a year to breakeven unless bitcoin drops further.

Just got my new T9+ from Bitmain.

Slightly different form factor. A little shorter and a little taller. Looking the kernel log, it has 9 chains of 18 chips instead of the original T9's 3 chains with 57 chips each. I am assuming if you lost the first chip in a chain that you wouldn't lose the whole board like on the S9 and T9, just that chain of 18 chips. I don't think the original T9 had this problem, but it would be a huge improvement over some of S9's failings.

Interesting that they would change up the design that much without giving it a new name instead of just putting a '+' at the end of the T9.

Why do this much of a redesign if the 16nm chip is at it's end of life as so many here are claiming?

Maybe the t9+ casing is the same as the upcoming s11? That would make a lot of sense as to why they did this overhaul. This could be a transitionary unit into the newer models. I am liking them so far. Running 4 right now two more come Friday.

One third of my miners are T9. All have been running for a year perfectly. But 3 S9 have bad hash boards within a year or less. Though they didn't cost much to repair by sending to Bitmain US site, it still took some time. So I don't mind to get more T9's for less price.

T9+ case appears to be just like the A3, interesting observation.

I have $100 & $200 coupons available for 40% off face value if anyone is interested.  PM me.

Guys remember the T9 and T9+ are completely different miners. They are physically different with different chip counts so you should post about them in the T9+ posts and not here so you dont confuse people.

Profit Not good Now ;(

I just looked online and Bitmain is having a sale on the S9 and T9+. A 14TH S9 with power supply is $1864 but you can buy T9+ 10.5T with power supply for $855. You could buy 2 T9+ for $1710 and have a total of 21 TH/s. I did the calculations with my power cost of $0.064 a kw at the current rate of BTC I would generate about $289.97 profit a month with the 2 T9+'s as opposed to $219.48 a month profit with one S9. I would ROI in about 6 months and even sooner if I got a hold of some good $200 coupons.

Am I missing something? It doesn't seem to make sense to buy an S9 at the current prices. 

If you are short on power or space the S9 might work out better.

Depending on my locations I have both issues.
1 spot has just about unlimited power (200+A of 220v) for me to use. So long as I can fit it in a 1/4 equipment rack.
The other my "warehouse" has as much space as I want. But with a little less then 40A of 110.
So yes in theory you are correct. But for me I would have to sit and do the calculations as to which would work better for me.

-Dave

ROI is beautiful in these T9 and from what i have read they are very reliable, they lowered the price to 755 with PSU. If you have 420$ coupons u cant beat that ROI. My power cost is around 0.05$

Your ROI calculations are off you are not taking into account raising mining difficulty. Also shipping is kinda expensive around 110$ per miner i bet you can find some 420$ coupons for around 50-80$

It makes sense buying a 14th/s S9 if u dont have cheap electricity, they are a lot more efficient...

T9 looking like an absolute bargain, im wondering whether these prices may go back up when the BTC prices returns to 15k+?

They called that like that mate for a good reason i guess. Hope many would profitable with this miner , interested with this one too but still don't have some capital.

Do you feel the difference?

Thats a huge /when...

But i guess they will sell pretty quick if the ROI gets even better

I bought 20 but it is a weird spot right now to buy, seems like there is gonna be a new miner from Bitmain at any momento, but at the same time from what i have read around the next jump in miners wont be that high maybe 20 th/s not like the S9 vs S7 4th to 13 or 14

T9+ Sold out  :'(

Available for me

https://shop.bitmain.com/product/detail?pid=00020180404091446982oShXnuLV0705

wow they're such a scummy company, had the t9 listed yesterday and was 30 bucks cheaper with the ability to use $400+ coupon.  Now I cant even use the coupon and the price has increased along with shipping, knew i should have gotten it yesterday.

I'm in the same boat as you. Was about to pull the trigger with my 420 off coupon. Hopefully, they'll allow their use of the T9 like they advertised...

Doubt it they're a scummy company with no morals lol. I swear they don't want to see anyone make a dime of them.

Is the reliability that  much worth the loss in efficiency ?

I wonder how it will be if I trying to buy T9, my electricity fee is around $0.12 / kw but unfortunately, I don't know much about how to calculate the fee in a month. the shipping is too expensive but maybe it could worth if we can get some coupons to buy. I think it will worth again if bitcoin price can increase higher.

$0.12 / kw is your price per hour. The T9+ consumes about 1440 watt per hour, so your hourly cost for operating one T9+ is going to be $0.1728 (Daily cost is $4.1472 and monthly cost is $124.416). Currently the T9+ makes around $5.83 daily (~0.00073 BTC). You will make around $50.484 monthly after electricity assuming that network difficulty and Bitcoin price will stay the same. Honestly, in my opinion I would rather buy bitcoin instead of buying the T9+ in your case. You can make the final decision but don't forget to factor in network difficulty and future bitcoin price.

Hope this helps. Merits are appreciated.

In my experience, yes.
Not to say the T9+ is super reliable, but more that the S9 is very unreliable, especially ever since autotune.

Are the T9+'s a good investment at $1500 including shipping. They same to be quite more reliable than the S9.

Not at 1500 considering they were selling for less than half that if you had a coupon, and they're still in stock direct from Bitmain. I'd suggest trying to find a coupon and buying direct from Bitmain, as they are currently going for $771 with a PSU. They ship out in just a few days (21-30 of April), and even though customs may be a bit of a hassle it's still better than paying double for one.

I'm sorry I meant 1150$. With cost per kWh around 9cents

You're going to break even in just over a year if BTC prices hold and difficulty also holds. The latter is extremely unlikely, and because of that I would suggest against it. Difficulty's going to kill you in the long run and draw out your break even time by a lot. Coin prices may rise, but you can't count on that when mining.

Tbh i guess bch should rise by the end of summer.

If you think prices on BCH (or even BTC) are going to rise in the future, it's a better option to just buy some BCH and hold versus buying a miner and mining BCH considering your electrical costs and the cost of a T9+ for you.

I advocate for mining, but in your case buying and holding makes more sense if you think BCH will truly rise.

Thanks for your help. I'll consider my actions.

It does appear that bitmain adjust costs based on btc / ltc prices, makes sense that they price like a commodity

No. It is possible to run these at home but keep in mind they are extremely loud at near or above 70db, and they're built to run on 220V though I know some people have found ways to run these on 110V. Some people even manage to sleep in the same room as these miners. How? I don't know.

There are ways to reduce noise, like with a wind tunnel philipma1957 built, but don't expect these to become quiet. I ran S9 these in my garage, and they were still somewhat noticeable from the house.

Put it in a cooler, it works!

i think they figure the reason of high S9 hashboard failure
it's the power needed for the chips!
so they produced T9 with 180 days warranty
each T9 board have 57 chips instead of 63 and need 480W to power instead of 400W
less chips more power!

You cant. ASICboost is a hardware level thing, no software is going to make it happen

I sent a dead T9+ back to Bitmain (USA CA address) and got the notification that they received it.
Does anyone have any experience with the turnaround time for repair / contact back from them?

Thanks,
Dave

Give it a month. For me it typically takes between 4-10 weeks. If it's out of warranty watch out for the repair order that you're gonna have to pay.

i sent T9+ back to hong kong, courier service delivered the faulty miner on 6th Aug 2018, bitmain updated the ticket to "Collected" on 7th Aug 2018 and sent out replacement on 11 Aug 2018, i will say their support team at HK/ Shenzheng are very efficient  ;D ;D  

I sent a T9+ to the USA CA address via UPS on June 1 and had a new unit in hand on the June 18

Got my replacement in the other day.
Very used miner, with a bad fan.  :(
Put in a spare fan that I had and it's off and mining. But come on do a little QC on it.
That or DHL dropped it. You never know.


-Dave

I think Fan 3 was taken off a small jet :-)

Seriously, anyone have any idea on what can be causing it so show that speed?

Temps are good, it's been up and mining for 2 weeks now since I last changed pools.
Checked in today to verify all was good as I got a notification from my secondary pool and saw the speed of a fan that does not exist.
