I’ve attached a screenshot of my HWiNFO64 results after running Cinebench 2024 and I’m unsure how I might tune my 4090. I can’t seem to adjust the voltage or power limit without screen artifacts, and when I adjust the core clock more than +150 and memory clocks more than +1000 it tends to just turn off the benchmark. It doesn’t seem like thermals are an issue, but the power and voltage reliability are limiting performance it seems. I have an ROG Crosshair VIII Dark Hero, STRIX 4090 Gaming OC, AMD 5950X at 4.55Ghz, 4x16GB Trident Z Neo DDR4-3600 CL16-19-19-39 at 3600mhz 1.345V.
Any advice or pointers to help me figure this out would be much appreciated.
