Above 6000 is difficult to run 1T
1.3 MC 1.25 SA should be enough (2x SR), adding more looks no benefit so far unless you have a good CPU sample with extreme cooling
VDD & VDDQ 1.35 not enough to hold 6000@1T
SK Hynix spec sheet regular daily use could bear up to 1.5v; for regular program mode, PMIC I remember is Max output 1.435v, you could try VDD 1.435 VDDQ 1.385 MC 1.4 SA 1.35
But my friends remind me basically they need to enable the high voltage mode for more to stay 1T, they rather running higher clock at 2T, which getting more benefit.
Alder Lake and Zen3+ prefer higher clock memory (to get higher clock on memory controller), the larger L3 cache makes the DDR4/5 memory latency not that important (but indeed still important somehow)
Mine Z690-F, weak in DDR5 OC
Some samples and data come from my friends, APEX, Hero and Extreme. APEX no doubt the best in ROG for DDR5 OC or tuning
MSI Z690 Unify-X should be another good platform, however, they have not received the sample yet
