I tried to overclock my Q6600 from 2.4 to 2.5 with only increasing cpu host frequency from 266 to 278, but I did not touched any VCore settings (I can't because my motherboard don't have those settings) and when I tested it with ITB voltage was at 1.312 but back when it was on 2.4Ghz the voltage was around 1.216.. So can anyone explain me what I did wrong or how can I keep increasing my cpu host frequency without cpu voltage increase because the temps went high.
