T3       yet to ship

T2T-32T

the gear above  is the most efficient gear there is for sha 256.

I am trying to determine if there is a reliability issue  with them.

I am aware that the T3 is yet to ship.

All of the units come with a psu  that you have to use.  So I am trying to figure out if they break easily.

Didn't you mention you had an issue with your T2 a while back? Or was everything fine?

T2 was good.

T1 not so good.

I have a Whatsminer M10s, a pair of Innosilicon T2T+ 32TH, and a pair of bitmain T15s currently under observation and testing to determine our next hardware purchase.

The M10 and T2T have been running for nearly 2 months trouble free now. The bitmain unit only arrived recently but I have seen no issues with it as of yet.

So far not even a hiccup other than having to factory reset the T15 out of the box.

You have the supersized m10  does 44th? or 54th?

The M10S is physically bigger than the M10 correct? With 4 boards instead of 3? 140mm fans instead of 120mm?

IIRC it has 140mm fans.

the m10 31th and the 33th have 120mm fans for sure.  I have 4 of them at the moment. 2x 33th plus 2x 31th

Pretty sure I am getting a fifth one. 1x 31th

The M10S is pretty big, it does have 140mm cooling fans but only 3 hashing boards.

The Innosilicon T2Ts are actually larger than the M10S and also come with 140mm fans.

The T2T32T or all versions? I never to get to see these things thanks to mostly drop ships.

Philip you expanding or taking s9's offline?

my t2t24  is bigger then my m10 31th or 44th not sure if fans are 140mm

I go to new build out today  and will bump from 30kwatts to 47kwatts

let it run for 2 weeks do final bump to 58kwatts

so 1 will need 11kwatts in some kind of gear  I think it will be m10's 5 or 6 more  no need to decide now.

That sounds pretty sweet. Maybe well see some info on the T3 or another batch of m10s but for the price right now with decent power cost the m10 31T is a pretty sweet deal.

From the S15/T15 thread sounds like batch one and two are a bit problematic? Might go do a quick peek at the support section here.

The pair of T15s I was able to get from batch 1 have no problems so far with 9 day uptimes. It not really enough timewise to go on, but so far these have been rock solid.

That's good to know. Efficiency wise they're on par with the S15 in LPM from what I've been reading.

My T15 is still hashing away without issue. 23.3 TH/s at the pool, ~1540 watts.

I am seeing 20.6TH @ 1434w in LPM on T15 #1
I am seeing 20.7TH @ 1403w in LPM on T15 #2

I'm seeing 21TH @ ~1310-1330w in LPM

So your t15's do very well  

what are your input volts?
200
208
220

FWIW the PDU I have mine on is reporting 210v at the outlet currently.

Panel says 208v but multimeter reading directly from the plug on the PDU says 200v.

We don’t have a lot of info yet but it looks like the psu prefers under 210 volts vs over 235 volts.

This could be a problem for USA SETUPS on 240 volts. As I type I am at 241 volts in my house.

Anyone with numbers for t15 s15 including volts feel free to post.

Got 2x S15 / 28TH from January and February.
Can't complain , no issues and hashing strong.

This is all very pointless unless you have hundreds of them.
If 'one' of the two you buy fails and 100 someone else buys are all OK, it simply says you were unlucky - only one in that 102 failed.
You'd need to find some large miner farm and ask them about failures otherwise it's completely meaningless.

I locked this.  It seems we ended up with 2 s15 psu burnouts reported which is not a lot.

Both were being subject to 243-246 as the high in volts and 240 is  the max according to bitmain
