Hi Folks

Finally got new build setup. Spec as follows:

10900k
EVGA XC3 Ultra 3080
Asus Maximus Hero WiFi

OK first pic below was stock out of box settings. This achieved 17065 in time spy.

I’ve just done a little bit of overclocking, both to CPU and GPU specifically:

CPU - 10900k - overclocked to 5.3Ghz in all cores.

GPU - EVGA 3080 - Core clock increased to 1880Mhz from 1750Mhz. Memory frequency increased to 10000Mhz from 9500Mhz. GPU undervolted to 831mV from 881mV to counter power max power draw issues on this card. Power increased to 106%.

New Time Spy score = 17300

Undervolting definitely helped with the power draw issue.

Hey there,

Is your xc3 ultra stable at 0.831Mv and 1880Mhz?
Mine is not, best I can do at 0.831 is around 1830, 1845Mhz.
I need 0.850 for 1860Mhz, and 0.887 for 1905Mhz.
If I'm willing to go lower than 0.831, I can either do 0.806 at 1800Mhz, or 0.812 at 1830.

I stress test the card with port royal on a loop or just by playing Cyberpunk. It takes a while for it to crash, but it does.

Thanks!

Yes stable at 831mV. I do keep power at 106% as opposed to 107% which crashes

Interesting, thank you!
I haven't considered the power percentage affects stability in any way, considering the card draws less power due to the undervolt.
