Hey guys, have any of you had an issue with V11.5, where when connection was lost to the pool, the miner resumed when the connection was restored, but at a lower hashrate?
At ~1:45am this morning, my miner lost connection, and when the connection was restored, the AMD cards mined at less than 50% of their usual hash rate. Strangely though, the NVidia cards on the rig resumed at their normal hashrate.
AMD Cards: Powercolor RX470, MSI Armor RX480
NVidia Cards: 2 x GTX 1050Ti
Hello man,
Unfortunately this very same problem strikes me from the very first day i started mining using Claymore (ANY VERSION).
I spent countless hours trying to beat this issue and here is what i found:
1. The problem is easily reproducible. Just start mining, remove ethernet cable---> reconnect ethernet cable---> BOOM stuck on lower hashrate.
2. Tried to use -minspeed parameter to no avail. The miner restarts but still remains stuck on lower frequencies.
3. Problem is related to PStates. Somehow after network reconnection, AMD drivers do not recognise the miner as a heavy enough load and apply a lower power state to the GPU that uses lower Core frequency.
4. -minspeed command being useless, the only way to restore full speed is to manually close and reopen Claymore.
5. As you too confirmed, Nvidia cards are not affected.
Temporary Solution i use myself:
Edit the vBIOS so that ALL power states use the SAME core frequency. That way you will be restored in full speed and be able run your rigs normally.
I hope this helped friend.
