This is nothing about skill, as you said it's simply IMC and/or board. No tweaking, just putting in and running. As simple as the fact that no matter what voltage or mems, at 7-9-7 for example same configuration won't even boot, both kits run til bclk limit single at 7-9-7 with 1,65v and less

I have been able to run 4X2GB on the 2133 divider but not when the cpu was heavily oc (i.e. 5ghz)

I never even tried a lower clock, regardless that is sick websmile, glad to see it is possible

well here is my findings after digging into it for the last few days.

Z68XP-UD4 - the data and address VRef settings appear to do nothing but break. The bios is indicating to me that the voltage should be .75 by gigabyte set default. This setting is very useful in getting the memory too cooperate at high clocks. I usually gain a touch by dropping the voltage .01v. in this scenario i would set to .74, however it when set to .75 as indicated or .74, or any other setting it wont post. This was tried on F2 bios and I know its not the latest so im going to re-test a little later.

Maximus IV Extreme-Z - the data and address vref settings work correctly. once corrected I was able to run 8gb 8-9-8-20-1T 2133 @ 1.65v. So for dram data and ctrl ref voltage its .490. I havent tried lower than 1.65v as this is stock voltage for these kits.

pictures are a different gskill kit but so far this method has worked for bbse and bdbg/psc. i have yet to test bclk with all 4 occupied.



*edit*

resolved the issue with vref on the gigabyte. turns out, that i was at fault here. vref is defined as vddq/2 so its listing it correctly when using 1.5v vdimm and i was not taking into account the rising dram voltage when inputting values. the methodology on asus is different in that it makes you input a ratio. hope this tidbit of info helps.
