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
