How is that possible? My CPU Vcore is 1.368v on Auto. If I go up to 3.8Ghz my voltage has to be set at 1.411v to be stable. I have tried adjusting the CPU-NB-Voltage as well. No help. I use Microsoft Security Essentials and it doesn't work right when the frequency/voltage's are not right. Strange I know, but it works perfectly when they are in Sinc.
Also, how did you get your CPU sig into your post?
