Max GPU Memory Clock on Idle Desktop on 144Hz

[bampi]

I have the same issue.

I made a backup first of my config. So at the CRU page, it says low vertical blanking causes this maxed out memclock. So I only changed the Vertical Blanking from 50 to 100. And it worked. Pixel clock is less than max of 600 Mhz (HDMI 2) so I feel it is fine.

1. Can anyone explain how this works?
2. Increasing the VB also increased back porch V and total V. Will this affect my monitor in any way? Like its parts, its health, gaming experience (flickering, etc)?
