strange thing is happening. i can't see why but when ever i cold boot at 2.4ghz my usb receiver for my Logitech wireless mouse and keyboard doesn't detect :/ despite the fact everything checks out as stable. i have to replug the receiver and then it works fine. some more clarity on the issue with high vdimm and vcore. the maximum difference between half vdimm and vcore that can be considered safe should be taken as 0.325v. that is the difference between minimum vcore (Cool n' Quiet at 1.1v) and maximum specified vdimm (2.85v). 2.85v/2=1.425, 1.425-1.1=0.325v. therefore the maximum we can assume is safe is 0.325v.
