Hello! I have a problem with my vega 56 gpu frequency.
My configuration is:
Asrock x470 taichi
AMD Vega 56
G.Skill Trident Z 3200 c14
Samsung EVO 970 250gb m.2
Power supplay Corsair Vengeance 650m
Windows 10 pro
I did program my vega 56 to vega 64 bios and overclocked it by WattMan. When i start any game or benchmark my GPU frequency is around 1600 mhz and it's stable.
But if i turn off my PC and start it again, GPU frequency decreases to 1565-1580 mhz. If i reboot pc ( don't turn off, just reboot) and start benchmark, frequency increase to 1600 mhz again. Instead rebooting, i can switch on HBCC module in radeon settings, frequency increase, but after turning off pc, situation is same. I using MSI Afterburner and GPU Z for monitoring. The only indicator that changes in GPU Z - memory usage (dedicated and dynamic), when frequecy 1600 it shows - 0 mb both.
No matter what bios or driver i use. Even on second bios with low power supply and balanced preset i see same problem.
