Reliability discussion thread, may not last long

So, we got Bitmain's S15s and T15s, plus Whatsminer's M10s, and Innosilicon with their T3, which hasn’t shipped yet, and the T2T-32T. These machines are supposed to be the best for SHA-256 mining. I'm trying to figure out if there are any reliability concerns with them. I know the T3 is still on its way. Every unit comes with a PSU that you have to use, so I’m curious if they tend to break down 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.
