Question OC+UV an Asus AMD RX 6650XT


Mar 4, 2018

I have OC'd and UV'd my Asus AMD RX 6650XT 8GB Dual Fan and I'd like to share my results.

I used Superposition to test the tunings, and currently I am at 2850mhz/2400mhz - (Samsung) Fast Timings/1.15v which I obtained a score of 6190. A voltage lower than that caused my PC to reboot when loading RDR2 and it was set at 2800mhz/1.13v when that happened.

This is a slight boost it seems from the default GPU settings which I tested on which gave me a score of 5759.

Should I go further or should I keep it as is? I think if I set my voltage to default 1.2v, then I can reach 2900mhz potentially, but then I have no undervolt. Thanks!

2800 MHz vs 2900 MHz is about 4%. You're not going to notice any performance improvement in practice.
This why I don't bother with overclocking my GFX card or system come to that.
It might be handy if your looking to obtain a score in a benchmark just to get those few (sometimes more than a few) extra points

In reality though

If your card is struggling at say 30 -45 fps in a game that extra 4% 10% or even 20% will not as if by magic make the game play feel that much better.

Take my graphic card for example, factory over clocked by a mere 60mhz, why? Lmao
