Bitmain Introduces the S19 and S19 Pro

[AlecMe]

i wonder how many were sold, as this will lead to a diff increase, plus the people who switched from BCH BSV, which probably will switch back after BTC halves (or i hope)

based on the price it is starting to look like s17+ is a better option, that and the fact that i missed the selling  .

BSV and BCH do not have a lot of hashrate. Even if everyone came to BTC, it wouldn't increase diff a lot. Also, S19/Pro are shipping in Jun, so we have almost 2 full months of mining before destroy us . But I think there is not a lot of S19's.

If you fear virus 🦠 do what i do now.

have ups/dhl drop it at my garage door.
bring it in
spray box leave it sit for 3 days.

walk out of garage wash my hands.

go back to package in three days.

Nah, I'm not worried about the Virus. I'm still working in the public everyday. I was wondering if the shipping routes/product import supply lines have been interrupted or slowed heavily because of the virus.

[mikeywith]

they also told me the international delivery for the first batch will not be 11 to 20 May but rather later around early June

 

well bitmain finally put the prices up $2633 for the S19 pro and $1964 for the regular s19 - add in shipping and tariff and its around $3500 for pro and $2700 for regular.

Shipping in June.

You are welcome for the hint  

Jokes aside, no go for me with these prices and the halving is due in less than a month

HOWEVER, T17+ and S17+ prices have been lowered while shipping times remained same (21-30 April).

I am having some issues with these guys, honestly, they don't seem to be reliable AT ALL, looks like they are just S17 pro overclocked to their max or more of the same chips on the same hash board, I have two of these at the moment, one had an issue with the control board and I had to replace it, now the other one is having PSU issues, so in a nutshell, these have 100% failure based on my experience and luck, as for the T17+ a few people whom I know including philipma1957 reported issues with them too, so long stories short; stay away from anything (+)

The S17 Pro,  T17e, T17 are doing well so far.

Honestly, I am starting to think that I should switch to MicroBt, I don't trust Bitmain's quality anymore and I am almost certain these S19s will be even less reliable.

I'm experiencing the exact opposite.  My two S17+'s have been running flawlessly since day one. Excellent temps and fan speeds.  My one S17e has had a few hiccups here n there, dropping a board, dropping offline a few times.

[philipma1957]

buysolar is running a s17+ it is really good.

we have a t17+ in clifton farm it sucks.

i would not mind ordering an s17+

we will be turning off 28 s9s that do about 315th.

if i order an s17+ and we bring up 2 s17+ that would be 140th to replace some of the 315th we are turning off.

we will be freeing 25-28kwatts

2 s17+ are only 6 kwatts.

it is tempting.

anyone have any coupons?

i would also consider getting more T17+ i would hate to see them end up doing only two boards.

they are pretty cheap.

i wonder if i pull the dead board and run with a psu and a controller if it works.

I think you mean T71e and not S17e? Well, Luck plays a huge factor in this, we don't have enough samples yet to conclude the results, for example, I have had enough samples of S9k to be sure that they suck, certainly not enough of anything of the new models, but for 2 out of 2 S17+ I personally take it as a bad sign and I will not be ordering them again, the T17e is not my favorite either, simply due to the power it uses, my favorite by far is S17 pro then comes T17.

That's 50/50, not a very encouraging result on your end either if they list S17 pro for $1000 that might be something.  

[philipma1957]

Maybe I get a t17+ it is cheap.

762 is pretty good.

the s19 and the s19,pro are back on sale.

[mikeywith]

You should really consider the shipping duration given the pandemic and its effects, local shipments that used to happen on the same day or in 3-4 days now takes a week and more to be delivered, and if things don't get much better - products coming in from China could be stuck in the way for a very long time, this indeed differs from one location to another, but make sure you call and ask.

Same here. My S17+ was running mid December @76.5TH/s and now since yesterday it is running 91.5TH/s w/o any problems.

[mikeywith]

It might be just my bad luck with S17+, or it is just a matter of different batches, again everyone is free to buy whatever they want, by the way how are the temps doing with 91th, are you using Asic.to?

[PopoJeff]

Another thing I noticed with the S17+'s vs my S17e or S17pro..... the S17+'s boot up way faster than the S17e or S17pro.   

If I do a reboot, or point to a different pool, the S17+'s are back up in like 2-3 minutes, whereas the S17e and S17pro can take 7-8min

Not sure about 91TH profile, I ran it for few hours and didn't like it's usage as it was preset. I went to manual OC and did 94TH/s @3750W and max temp on middle board (but only on one temp node) was 85-87C while ambient is between 20-25C. Other hashboards were sitting between 70C and 80C.

Same here, S17+ boots as fast as Z11 but S17Pro and S17e boot same as S9 (takes hell of a lot of time).

From my perspective, you are correct. Bitmain's overall 7nm units are far from robust or reliable. I have had the best luck with Pro's but they still exhibit a 15% attrition rate on my racks. 15 out of 100 have lost boards, burnt PSU's. Out of 200 S17's we are experiencing 20-25% attrition with many lost boards and plenty of burnt PSU's. We are finding that the " High Temp Solder" on the boards is NOT performing at the temps that specs would suggest. Heat Syncs are coming loose and falling off along with failing solder connections. I believe you are wise to observe that Bitmain's QA/QC has taken a drastic turn for the worse. I am committed to avoiding ALL new Bitmain Products and focus on Micro BT. The final nail in th coffin for Bitmain was their clsing of thr CA repair center. So even warranty work incurs a very expensive shipment to China for repairs.

[mikeywith]

It's really nice to hear from someone who owns what I consider to be a good sample size, and since the attrition of 15% on the S17s pros and 20-25 on the S17s it's safe to assume the average is 20%, and honestly, I am quite sure it would have been worse if you got anything else aside from the pro version.

The one thing I would like to add which I have missed in my previous comment is the fact that it's really not just the 7nm technology that is making Bitmain's gears quality look like shit, it has to be something else, I am saying this because even the new S9 models which are built on 16nm are way far from robust when you compare them to the previous models, this has to be something with their quality control, maybe some very essential engineers left Bitmain, maybe they are desperately trying to reduce the cost, I don't know what caused them to start making shity gears like this but I know that the S19s will most likely be less robust, or at best case scenario - they will be as reliable as the S17s.

[favebook]

You got a good point, but at this price premium of S19s, I'd expect them to be a bit more robust and better in overall quality. But we will see in May/June how that turns out...

yea I noticed that late last night but the tariff and the halving make those very unappealing, to me at least.

[HagssFIN]

I guess that Bitmain thinks they'll get orders even though the price is high, especially in the situation after the halving.

It's crazy that they can do close to as they please with the prices and there still will be people buying hw.

[philipma1957]

They are far too highly priced.

Lets project coins at 12000   after ½ ing.

that would be 6000 now.

You don't get the gear until July 10.

if diff stays at current level and coins are 12000.

On july the unit earns 110 x 0.0904 =  just about 10 dollars a day  it burns 75-80 k-watts 2.40 at 3 cent power.

10 - 2.40 = 7.60 profit  3cent   you pay 2800 if tax is zero  368 day to break even  from July 10 which is July          13 2021
10 - 3.20 = 6.80 profit  4cent   you pay 2800 if tax is zero  411 day to break even    "     "      "     "      "  August     25 2021
10 - 4.80 = 5.20 profit  5cent   you pay 2800 if tax is zero  538 day to break even   "     "      "     "      "   December 20 2021

this is with fully flat diff and a 12,000 coin price Just don't buy the gear.

note with free power 280 days and no import tax is April 23 2021.
