Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v11.5 (Windows/Linux)

Has anyone experienced hashrate drop in what seems to be a quite consistent matter?
I'm not talking about my rock solid RX570 rigs, they've been absolute beasts for a year now. But I'm struggling with the Vega rig.

All GPUs will hash at ~41MH/s until one decides to drop to 26 for a minute. Then goes back up to 41. This happens regularly.

Surely if it were temp throttling (which seems unlikely as I have the fans running at pretty much 100%) the hashrate reduction would be more gradual... and not bam!... down to 26?

Any clues? I'm on v11.4, latest Adrenalin, Vega56@64, safe softPP table with specific clocks and voltages set in Claymore miner.

Got the same issue but with my rx580 rig, all 7 cards running stable at 31 mh/s. From time to time gpu0 suddenly crashes to a rate around 5-10 mh/s and after a few minutes hits back to 31. There are no error logs showing up, also no incorrect shares and temps are fine. Card has also the same setup as other cards (no oc), kinda strange since it just appeared lately, running currently v 11.5

same issue here
are you using stock rom with no oc?

In addition to the above, Mr Claymore, your miner reboots my rig every hour. Almost without fail. There's no error in the log, no watchdog issue with GPUs OpenCL issues, nothing. I'm baffled.

1. Unstable speed - I see this issue sometimes on different cards, but I have no idea about the reason - miner executes jobs on GPUs in the same way all the time, but sometimes GPU becomes slower for some time. I noticed that often different "-ethi" value helps, try "-ethi 4" or "-ethi 12" and see if it helps. I think that it must be something related to AMD drivers but I cannot confirm it yet.
2. I have a few rigs on v11.5 and they are working for days until I restart miner to perform some new tests, but I always use non-overclocked cards and default bioses, I have to do it to exclude everything except miner in case of any problems. When you use miner on overclocked/unstable rig you cannot be sure that the reason of the problems is the miner, but of course you will blame it Wink

Try to reduce "-ethi" value, if it does not help you can use the version that works fine for you.
