Question Is there a real difference between 16 gb and 20 gb of video ram for gaming

MSI Afterburner is an overclocking (and underclocking) tool compatible with all graphics cards. It also is compatible with AMD GPUs. This picture is of an NVIDIA GPU which has slightly different overclocking mechanics, but what I did is moved back the core clock slider 80MHz, and all problems left me instantly. Also, I core clock not memory.

look up on YouTube about undervolting. You do it through the AMD software but you can set ram speeds, fan curves etc all right there.

That one should give good info. I followed one of his videos regarding my xtx.
Speaking from my experience (also 7900-XTX) the reason to underclock is to tell the GPU to use more volts per clock speed (MHz). Undervolting I believe would act the opposite and cause it to perform less stably. But maybe that's the case.
 
I have another problem that the moinitor is tearing the image but i have vsync on. I looked in the options of radeon rx 7900xt I had enhanced sync on. I don't know how else to fix the tearing issue. I really hate this card
 
In my experience, Freesync helps more than enhanced sync (if your monitor supports it). I play at 1440 so tearing isn't generally an issue for me, also try capping your frame rate at 60hz might help, so you could give that a try too.
 
I have already tried every suggestion to fix the problem. I can't get rid of the problem. It keeps saying Default performance tuning settings have been restored due to an unexpected system failure
Late to the party, but unstable RAM overclocks (including XMP et al) can result in this error.

EDIT: Make sure your system is running bone stock - including RAM - run the extended Windows Memory Diagnostic test on boot (hit the super key and type "Windows Memory Diagnostic"). Report back with the results.

I have to admit I’m going to get a chuckle if the op comes back after enabling free sync and downclocking the vram slightly and decides he likes the card.

I do get though AMD can have a little bit of learning curve but they really do make a decent gpu for the money traditionally.
