Today i made a new test and when run amdinfo command seems that the GPU and memory are only working as 300MHZ and dont pass this:
=== GPU 0, 01:00.0 /sys/class/drm/card0 ===
Adapter 0: Ellesmere [Radeon RX 470/480/570/580]
Core: 1160 MHz, Mem: 2040 MHz, CoreOD: 0, MemOD: 0, Load: 100%, Temp: 65 C, Fan: 47.8431%

Core: 300 MHz, Mem: 300 MHz, CoreOD: 0, MemOD: 0, Load: 100%, Temp: 49 C, Fan: 47.8431%

The First one is from one RIG that runs RX580 8GB Powercolor (Hynix) and the second is the RIG with problem that runs same boards but with Samsung memory. Core and Mem are stucked at 300Mhz…
