I'm attempting to tune my 9800x3D via Curve Optimizer. I've been using AIDA64 stressing CPU, FPU, cache, and memory. My methodology has been to run the test for ~3 hours, and if it passes, bump each core negative offset one at a time by -5.
I think I almost have something stable dialed in, but AIDA64 is now failing at the 15-hour mark. Not really sure how to go about isolating which core needs adjusting. I've also tried running CoreCycler 0.10.0.0 with all the default settings and it ran for over 32 iterations over 24 hours passing everything.
So far, AIDA64 has been faster at telling me something is unstable whereas CoreCycler has never thrown any errors, and I've read somewhere that it's not great for testing stability on the 9800x3D.
I know there are other tools like Prime95, y-cruncher, and OCCT; which one can inform me of system instability faster and tell me which core is failing? Or are there certain CoreCycler settings I should be using?
In terms of every day usage, I haven't noticed any crashes. The only abnormality I noticed has been that the system is sometimes unable to POST following a reboot with a yellow DRAM LED indicator. I have a hunch that this is related to a +200 boost clock override rather than Curve Optimizer, but not sure.
Edit: Also just ran OCCT for 1 hour cycling through all cores with no error.
