MSI Z270-A PRO with 7 GPU used to run  fine for almost a year. Suddenly yesterday I had ~50 restarts so I tried to figure out what is going on.

Didn't find any suspicious change notes so I started to review my hardware.

First: It is mining well for about 4-10 minutes then it shows error "gpu fault detected 147" after this error all GPUs still mining for about 10 seconds then instantly reboots with command: "sysrq resetting" which isn't any watchdog of Claymore.

What I tried already: reduced OC, increased voltage, different PSU, brand new risers, checked all cables if they are burned or heating up fast (all were fine, healthy and cold) and it's no change.

Guys what has happened, have you any suggestions? My script which worked fine for some time looks like this:

AMD RX 570 with dag fix works perfect! 950W in dual mode @ 6 GPUs. Undevolting @ 880 mV stable.

I'm before migrating to SMOS on my other RIGs is there possible to define different undevolting values for any cards like OC?

I'd like to test gambit indicators, my TV id: Apolyon

I have 1070's I didn't want OC it at all but I guess I have to otherwise SMOS won't even start miner with null values.

Hey guys I have problem with NV version of SMOS


It looks like this and then it's nothing happening. Tried many reboots, OC settings etc. Any ideas?

Hello guys, any of you tested MSI RX 580 Armor 8G OC HYNIX ? I can't do more than 27 MH/s with straps 2:1750 and OC 1150 / 2150.

Did all straps like 2:1500 - 2:2000 = crashing after Windows booted up.
2:1625 = with stock setting crash after miner starts work.

1:1500, 1:1625, 1:1750 = no effects at all.

Any ideas? Or I'm doing something wrong?

Or this is gabage gpu and mems? I could return them and try with something else. What you think?

That's the real tip. Thanks.

Start you SSH client, log on your miner f.e. ssh miner@192.168.1.10 password is "miner", then list screen sessions "screen -ls" it will show screen session ID of your working miner, just use screen -x ID.

Hope it works on Putty in same way.

You have right. Why is that GPU so vulnerable on heat compare to other ones? How can I cool it down? Is there any way to set GPU fan speed seperetely?

I'm successfully dual mining ETC + SC but one of my GPU has lower hashrate than others. Never did dual mining before I have set dcri to 14 and I think it's optimal for the rest GPUs.

All GPUs have same Elpida's memory, they're same manufacturer and same modded bios. Have you any idea what's happen to that GPU 4?

When I solo mine ETC hashrates seems to be ok, no drop on GPU 4.

Hi everyone.

I'm using SMOS from 14 days - great job Tytanick. Today I wanted to try Dual Mining with some Pascalcoin. Did the proper settings in Claymore 9.3 and my hashrate for Ethereum dropped to 50% of normal speed to about 13,5-14 MH/s per GPU while Pascal was around I believe ~2500 MH/s in total.

What have I messed?

My RIG is 6x RX 570 Gigabyte Elpida @ 1060 MHz core clock, 1940 MHz mem clock, power stage set to 0, 820 Watt from wall - it was stable for 14 days on Ethereum solo at 164 MH/s.

For Dual Mining I tried to even set power stage to 5 but it doesn't work either, seems like mining Pascalcoin is prioritizing over Ethereum.

I'm newbie miner, if this issue isn't software related please forgive me and ignore my post. Believe me or not, had tried to solve it by myself already.
