Not to mention in heavily threaded games where a variety of threads are spread out over both CCDs of a 5900x, and each CCD has 32MB of L3 cache, the advantage of the 5800X3D in L3 cache is only 32MB, and the disadvantage in stock clockspeeds and the inability of the user to tweak PBO2 settings and the Curve Optimizer very much cloud the issue. Bios is AGESA 1. Hey, I 'm using ryzen 9 5900x. Another question: Is PBO2 & Curve Optimizer safe to run? Are the CPU safety features (voltage fitness regulator) still in place? I avoid manual OC because it disables these features and it's not as good as the CPU's regular boosting, so it'd be nice to know if PBO2 & Curve Optimizer are safe or not. I've finally settled in on the optimal tuning for my 5900x, and wanted to share the results as well as a short guide on how to get the best out of your zen 3 as well!

Curve optimizer -26. APIC ID10, that’s core 5 I think, I think you can use CPU-Z to write a text report that can correlate all the APIC ID to their corresponding cores, search up how and then you can use PBO2 to add or decrease voltage to that particular core, probably add to that core for more stability, but you have to be careful as that is technically why overclocking can be “damaging”. When combined with very high all core frequency and curve offsets, my guess is that it generates a lot more heat than the algorithm expects at unmodified frequencies. black OLOy 32GB (2 x 16GB) DDR4 3600mhz ASUS AM4 TUF Gaming X570-Plus Have you tried playing around with PBO2?
