RX5700XT with 144Hz monitor - High vRAM Usage and clocks

Hi,

As title says. I just bought 144Hz monitor LG27GL850-B and I've got wierd problem with vRAM of RX 5700XT.

There is no Overclocking made.

OS : Windows 7.

Driver 20.2.1 ( 20.2.2 is making my computer to restart at random events )

When refreshing is set to 144 Hz, even on idle my vRAM usage is about 47% and clocks are at 1750 MHz !!!.

When I set it to 120 Hz the vRAM clock drops to 200-300 Mhz but usage is still at 40+ %.

I've also made a resolution profile where I set refreshing rate at 142 Hz - at this setting VRAM clock is also at normal rate of 200 Mhz but again VRAM usage at 47 %.

WTH is going on ?

Does anyone had/has similar problem ? Any ideas how to fix it ?

hardreset- I have seen your video. It helps to keep clocks on 200-300 Mhz on idle system but doesn't solve vRAM usage.

Right now I have 1,4 GB vRAM used on idle system - WTH ??!!

There is also one problem with your idea - color depth. If you set it up on 142 Hz and reboot system, you won't be able to set color depth more then 6bpc...

Yes, I know that, we feel until amd do something about it. This is my temporary proposition. For gaming proposes to set 144Hz
