VRAM is more than 100%, is it ok? My CPU is AMD 7950x, with iGPU, and a few displays - is that mean that I need a discrete GPU? #168

On idle system.

That it exceeds 100% is what the kernel reports (bug or at least a misleading report), nothing we can do about that. For your second question, it does look like your game/app would run faster if you had a GPU with at least 2GB VRAM.

No games, just Firefox, and it feels sometimes laggy :(

I got AMD 6800 XT: image

Memory clock to 1.00G is ok?

Seems so: https://www.techpowerup.com/forums/threads/how-to-calculate-gddr6-speed-from-gpu-z.250747/

This may be because vramsize (usable heap size) is a dynamic value, but radeontop only get it once and uses it.
