Optimizing Ryzen 7 7800X3D: Best PBO Curve Optimizer Settings & RAM Timings
After extensive testing across 4 different AM5 motherboards, here is a breakdown of optimal PBO -30 offsets, SOC voltage limits at 1.20V, and tighter DDR5-6000 CL30 sub-timings. What curves are you running on your setups?

Can confirm -30 all-core is stable on most 7800X3D chips, but on heavier AVX512 workloads core 2 threw WHEA errors for me. Ended up running per-core with -24 on the preferred cores and -30 on the rest. Rock solid ever since.
What FCLK are you running? 2000MHz 1:1 with DDR5-6000 CL30 seems to be the golden ratio for AM5 latency (~61ns in AIDA64). Anything higher than 2133MHz FCLK caused memory controller instability.
