Hey i have found another bug.
right now i'm using HDMI cable so basically my maximum monitor refresh rate is 120hz.
suddenly a new bug came up.
blank green screen then freeze crash then reboot.
steps to reproduce:
right click desktop -> display settings -> advanced display settings -> display adapter properties for display x -> monitor
choose a lower refresh rate. and use PC for sometime.
Using A Lower Refresh Rate Fixed The Wrong VRam Memory Clock Speed.
I Wish You The Best Of Luck Fixing The Issue.
