PC Graphics

I found online that windows drivers permit memory overclocking for 7900 GRE up to 3000 MHz. However when I check the same for linux in the driver file pp_od_clk_voltage, the max memory frequency is 1158 MHz (x2 = 2316 MHz). Anyway to overcome this limit on Linux?

You might have mistaken the graphics clock up to 3000 OC, a memory clock from 2250 to 3000 i would doubt?

found the solution. Installed amd rocm drivers on linux. The amdgpu kernel module limits the extent of overclock. Installing amd rocm software amended the situation.

The pp_od_clk_voltage file shows the following:

OD_RANGE:
SCLK: 500Mhz 2803Mhz
MCLK: 97Mhz 1500Mhz
VDDGFX_OFFSET: -350mv 0mv

It allows shader clock to reach 2803 MHz and Memory Clock to 1500 MHz (x2 DDR = 3000 MHz).
