Boy, how easy it was to hit 4Ghz Uncore/Dram 2Ghz with QPI setting on AUTO, although the board did increase the QPI voltage to about 1.475v, and I only used DRAM voltage 1.64v.
And this time the run was even better when the CPU multi on x21 than x19
Right now I topped at about 210 Bclk, x10DRAM/x20Uncore, 1.65v QPI/1.80v Dram and 21x CPU with Turbo and HT=on.
It was unstable for SuperPi32M but I managed to Pull SuperPi8M and wprime 1024M.
If I could just hit 215 bClk with the same multies and run SuperPi32M I bet I can go sub 8M
Too bad those ram just don't like anything above 1.8v !, this is the sweet spot for these sticks.

Bottom line, A crappy ram can also be a burden on your IMC so try to use different ram and see if its your IMC or just bad ram.
So, do you think my RAM is a burden to the IMC even if I keep the RAM way below its speced speed?
