i7 920, overclocking question

Vir · 29 Mar 2011 at 08:41

Got a little question, when I overclock my CPU to 4Ghz it runs pretty stable but sometimes peripherals like keyboard or mouse don't work (no power) on boot or applications load very slowly, for example intel matrix storage application.

I reckon this has to do with voltages being a tad to low? Anyone know what voltage this specifically could be?

I would try bumping up the QPI/VTT and NB voltages a little bit, as it sounds like memory controller related instability.

Memory controller yes?
Hmm ok I'll try the voltages and look for some kind of template of what others are using at 4Ghz

My Motherboard is a biostar which is a little different but for 4Ghz I use :-

Vcore 1.26
VTT 1.30
NB 1.13 (default 1.1)
QPI/PCIE 1.22 (default 1.18)

Thanks mate, I'll try that tonight!
