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

this happens to me as well for hardcoded bios.
temporary solution is disable p0-p6 in overdriventool. or hardcode your bios to use the same clocks on p0-p6.
this must be a bug, since this is not happening on previous versions.
If you're having this issue on Windows (10), Windows has probably updated the Video Card Driver with his own new driver. Solution: remove this driver and install AMD's Mining drivers again. This solved my problem.
