Relating to this HWBot submission, where you did 4800 14-14 SP32M:
https://hwbot.org/submission/4712591_dimon.sava2010_superpi___32m_core_i9_9900k_5min_29sec_589ms
an you run fully tightened subtimings? Like tRFC 220, tRDWR_sg/dg 10, tWRRD_sg/dg 26/21 or 25/20, maybe tCWL 13 or 12 if all previous works. Does tRCD 13 or tighter RTL (56/56, 55/56, 55/55, doesn't necessarily need IOL 6 but might) run SP32M?
Is 4800c14 the max for this set? Maybe could try 4800 ratio, drop core and cache by one ratio, boot 100.3 bclk and raise to 102.1 in OS, needing 2.03-2.05vdimm. Did you use waza?
Thank you for your patience.
