The drop under load is not much i use very high LLC and the voltage under load is the same as i use in the bios it does not drop so i didnt use the extreme option.
I have reduce the cpu volt freq to 350 and now the voltage does not change so much and the temps have dropped a bit
i havent overclock the memory i use xpm to 1866. I dont want to get slower latency for higher frequency . 1866 at CL10 is decent... i think ...
