I have a problem with a new rig 5 gpu (470 8gb nitro modded) two gpu start at full speed 29.2 and down in five minutes to 15 and 20 and the same happens in gpu-z memory controller load from 100 to 65.
What is the problem, someone can help me?
I confirm, having these issues since yesterday. Hashrate sinks. Out of the blue.
Had 5 RX 480 running 30+ mh/s now only 28+ mh/s. Got them stable again. Had OS problem so reinstalled along with the AMD 16.9.2 drivers.
For some reason BIOS part number for 2 cards show 'xxx-xxx-xxx' instead of 'normal name'. Stock values don't help, MSI AB doesn't help to get 30mh back.
Guess will have to reflash bios. But Sapphire Nitro with the little switch to the other position did not help to properly detect bios name either.
Any1 had these problems and fixed 'em?
