I have a 5820k OC to 4.6 ghz @ 1.3v along with a GTX 1080 Ti and a 750w psu.
I've managed to OC my kingston ddr4-2400 (4x4GB) @ 1.2v kit to ddr4-2666 @ 1.25v. Same Timings (15-15-15-35-2T)
I've tried 3200 @ 1.35v (18-18-18-40-2T) however its only stable when im not gaming and if i do game it usually crashes/hangs/bsod after a couple hours.
What other voltages do I have to play around with aside from vDimm? I've read around VCSSA, VCCIO etc should help with weaker IMCs.
Should I up my vDimm to 1.45V and test in increments of 0.01 from VCSSA - 1V until i reach stability?
I've also heard VCCIO needs to be 0.5 below VCSSA to ensure stability, is that true?

Hi,
You should try 2800 and then 3000 first getting each stable

But you do have this backwards as far as I know
VCCIO needs to be higher
I'd usually go 1.1 on it and VCSSA at 1.05
