RAM is stable @ 2666MHz 11-13-13-35, 2T , 1.65V , VTT/VCSSA 1.175V.
But regardless of what I do IT STILL HAS LOW PERFORMANCE compared to 2333MHz 10-12-12-31 and suffers of "Write performance bug".
I tried everything I could think off for 2666MHz:
1.25V VTT/ VCSSA
1.7V DRAM voltage
130% for VCSSA and DRAM digi
Extreme for DRAM LLC
Which bios are you on, I'd set it to high vs Extreme, also do you have INRUSH disabled? It's directly below LLC, also set both VCSSA in the same area to optimized and 130%
Can you post your full bios settings, take screenshots then post them in line here for each section.
Also again please post your 2ndary timings.

Pretty much all rigs will be diff, however in these cases vcore/VTT/VCSSA are primary areas,
I'm lucky enough to have 1.1 for my VCSSA for 2133 @ 64gbs, however I cannot push my CPU to 4.6 since it requires a full volt which isn't worth it IMO.
Oddly it doesn't work on 0603-0801 but on 0602 (which is Raj's personal sauce ) everything is flawless.Edited by LunaP - 8/20/15 at 12:22pm
