Would the same assumption that you need more SA volts for like Dual Rank vs non Dual Rank ram chips? Trying to run on a 9700K 1.18/1.2 Vccio/VccSa for 3200 cas 14 2x16gb @ 3600 MHz resulted in my system being hosed after a Windows update. Perhaps needed more volts?From what I’ve learned is that the VCCSA (system agent voltage) and DMI voltage requirement is directly related to how “fast” your ram is.
For example, c16 at 4400mhz command rate 1, makes me need 1.29v SA, 1.22v DMI. The VCCIO voltage is related almost directly (but not entirely) to whatever your cpu cache frequency is at.
Having my ram at c14 3800mhz, command rate 1, also requires me to have my SA at 1.28-1.29, and dmi at 1.21875-1.225v.
Having my ram at c15 3900mhz, command rate 1, which is slower than the two configurations above, only requires my SA to be 1.26-1.275, and dmi at 1.21-1.22v
Just some observations that may help whoever reads this.
These observations were done on a asus Maximus hero xi wifi motherboard. LLC set to level 6, with AC and DC internal loadline set to 0.07 for both.
