I tried Vdimm mod and it works grate. But before you do it, please delete your OC profiles or at least, change DDR voltage back to default. I'll tell you later on why.
Mod:
Mem read points. That is the first try, I used too big VR



That's my final - ofcorse, you can use switch and a 1K3 resistor aswell for 2,0 startup or 600R for 2,35 startup.



And now the reason of deletion.
I set 2,3v for startup (minimum for my OCZ sticks), vent into BIOS and loaded my max profile. But there was set to add + 0,750v for DDR. So, F10 and multimeter showed me 3 - 3,2v for some time. That floating is not because of the vmod - voltage floats even with def settings from 1,8 to 2,0. Sounds like it has been set to find the minimum voltage for memory.

And now those sticks are in a freezer
