Here's a quick view running Furmark, I ran it for an hour earlier with very similar results Single-loop with the 7900X at 4600mhz, rad is an Alphacool UT360, with 3x Scythe GT 1200rpm fans. Quite decent performance anyway, need nothing more really for iRacing ... edit: Doing ray-trace looping at 0.975V, 2050mhz. Let’s see if she can hold stable, fingers crossed and praying to all known Deities. -> Nope, ave clocks were only 1,812MHZ...CRAP.... edit2: At the end, settled for 0.875V, 2,020Mhz. Run the complete gamut of 3dMark tests, including stress-tests, and stable as hell. No issues, not a single abort et al. If I don Port Royal and a few other benchies, holds the clock very close to 2,000Mhz, raising Vgpu, simply drops clocks back, so most likely hitting power-limit. Anyhoo, pretty happy with the result, average load-temps remain below 50 deg C. Will run a Port Royal stress-test overnight, suspect it will pass with flying colours though. Tomorrow, will find a full hosted server on iRacing and see how that goes.
