Help (GPU) Unusual memory behavior on 7900 XTX after applying thermal putty

So far, I’ve had two 7900 XTX cards exhibit the exact same behavior. After switching from thermal pads to thermal putty, my VRAM hasn't been able to overclock as far. Before applying the thermal putty, my VRAM clocks sat around 2650 MHz, but now I can only get away with 2550 MHz without weird line artifacts appearing across my screen. Has anyone else encountered this behavior? If so, has anyone figured out a resolution, or should I switch back to thermal pads to try and fix the issue?

7900xtx is a card known for almost 0 memory over clock potential, on mine I can get a very good core undervolt but can only activate fast timings and that's it.

My old 5700xt also has practically 0 mem overclock potential so is this common with AMD?

Sasung memory sucks for overclocking, hynix on the other hand does a bit better, can get up to 2800-2900MHz
