im currently overclocking my P4 (which as far as im aware arent well known for amazing overclocking) its stock clock is 3.0ghz and ive brought it to about 3.65 -ish with no problem. temperature only rose by about 5C!!! which is great for 600mhz increase. what happens is, when i go past the 3.7ghz mark the pc wont boot up even though my temperature is relatively stable. i dont want to up the Vcore setting too much but would it help? or is it just getting too fast for the lil penty to handle?
