I've got 2 4K 120Hz monitors and VRAM isn't running at full speed but it is higher than I'd like (for example my 7900 XT idles with the memory running at 909MHz).yeah its a nightmare
ive got the issue that my card has 2 hdmi and 2 dp and my monitors have different refresh rates available over the two connection types so ive either got to replace one of the screens and run a mismatched set and also id have to find one that worked well with the other two so kinda a tricky situation hence why i bought a second gpu
turns out that buying a second expensive gpu might not have actually fixed the issue and might have just added a second problem lol
wouldnt be so bad if the fans on the gpu ramped up when the vram gets hot but it doesnt if the actual gpu temp is not reporting high it wont ramp the fans up
so the only other work around is to just set the fans flat out at all times which well is loud to say the least
bit of a headache this one lol
Doesn't seem to matter which connections I use either. Happens on both my 7900XT and my 9070XT.
I did find on my 7900XT that if I set one monitor to be 120Hz and the other to be 60Hz it drops the memory clock right down to low double digits. However I think if I restart Windows with those settings it goes back to 909MHz (or possibly then runs at 100%, I don't remember).
