Firmware is not bad at all. My T17s draws 2150w on stock settings (40THs) with Bitmain fw, with custom fw on 45 ths, power draw is 2000w. Chip temps are 10c lower. Only objection is auto fan settings. For example chip temps are 50c and fan speed on antminer is 6000 rpm, this can be reduced a lot, also power draw will be reduced more. I hope this will be fixed with next release. Also I noticed power draw peak before miner start hashing.It goes 10-15% up, this also should be fixed. Everything else is very good. Very good software.

Bitmain firmware is crap, they release their sowtware with no testing. I installed last Bitmain S15/T15 firmware (released on beginning of January 2020) after that 3 hashing boards on my T15 antminers are dead, and one powersupply is dead, boards constantly goes off on all miners. Bitmain of course told that is my mistake. But after I flashed previouse firmware all starts to work fine.

Hello guys, I have small amount of BCH coins, what is easiest way to split coins to BSV and BCH? Can some exchange do that for me?

Thank you.

Thanks for this information.

Hmm, ok. Antpool fee for pplns is 0%. That is reason why i chose them. Maybe I will try slush pool to compare profit.

What about Antpool? They are not good option?

Does anyone have some good setup for T17 on power consumption bellow 2400w? I tried a lot combinations yesterday, my T17s in this moment works on 740mhz/16,8V/2270w/44,5Ths. Nothing better for now...

Can you post some pics of your achievement ?

Anyone found some sweet spot for T17 on low power consumption? I tested a little bit yesterday, got 42 ths/1950w.

T17/S17 fw specs looks great. I will try this in next few days.
Is there any chance to make some good custom firmware for T15/S15 units?

Hi guys,
I have some nob questions.

I never used different pool for my antminers (sha256) than Antpool in last few years,I was to lazyto experiment, shame on me  . Now I thinking to change pool for a first time. Currently my miners works in PPLNS mode, they told that fee on Antpool is 0%, but calculation showing different, my earnings are a lot lower. On Kano fee for PPLNS mode is 0.9% but somehow i fill that my earnings will be higher than on Antpool, I dont have time for experiments in pplns because it could take long.
Can someone tell me, will my earning will be increased here? Thanks .

I got answer from Brainacs recently:


There is possibility that they will miss 15 series. It is lot more profitable for them to go directly on 17th series.

Is there any custom FW for T15 or S15?

True, but we all now if they cancel order i will get back only amount in USD which i payed.

I dont want to cancel order. I payed for my order in May with btc, when BTC price was about 5k. Hope I will get my shipment soon.

Hi guys, does anyone have problem with Bitmain shipping time? I still waiting for my august batch, still not shipped.

I got T17 38ths version. Power consumption is 2050w on 232V.

It looks like Bitmain released new FW for S15/T15. Release date is 07.05.2019, but firmware description is same like previous version. Does anyone tried new firmware?

Thank you on answer.
Price of electricity is 0.08 USD. Maybe I will try to turn on again my dusty D3s .

D3 is profitable on WolfpackBOT coin or not?

@braiins Is there any chance to make FW for T15/S15 antminers?

Hmm, so If specs are true. S15 and T15 buyers are fucked up again. Huge different on same 7nm chip. I hope Bitmain will release some good firmware for S15/T15 which will increase performance.
