[SOLVED] Getting low VRAM frequencies on RX 7600S

I have got an ASUS FA617NSR laptop which has got only dGPU and 165hz eDP panel.

While playing games when we all expect VRAMs to work at highest frequency that is capable of, I get 1000Mhz instead of 2000Mhz which my VRAMs are capable of.

Notes: I have got these kernel parameters:

amdgpu.dcdebugmask=0x10 (in order to fix green artifacts and freezings)
amdgpu.ppfeaturemask=0xffffffff

The output of sudo cat /sys/kernel/debug/dri/1/amdgpu_pm_info :

GFX Clocks and Power:
        96 MHz (MCLK)
        100 MHz (SCLK)
        1226 MHz (PSTATE_SCLK)
        1000 MHz (PSTATE_MCLK)
        98 mV (VDDGFX)
        1.00 W (average SoC)

Re: [SOLVED] Getting low VRAM frequencies on RX 7600S

My Guess:
DDR Memory = Double Data Rate Memory
^ this essentially means two blocks/bits/whatever are transfered per cycle.
2000 MT/s (megatransfers) = 1000 MHz
Many specs and sellers tend to confuse MHz and MT/s

Currently can't test on my own card, I'm not at home. But I remember having to half the clock speeds when I overclocked my 7800 xt.

Why I run Arch? To "BTW I run Arch" the guy one grade younger.
And to let my siblings and cousins laugh at Arsch Linux...

You are right, thank you for spending time on this topic.
