Now I overclocked my Q9450 to 3360 fsb at 420MHz, 333 strap te V-Core in Bios is set ti 1.2750 the NB is 1.35 V the 1.3 V everything is at low voltages and my systems boots fine I run OCCT for an hour no errors also Prime95 for an hour also no errors BUT when my system is in idle mode I leave it to download something it restarts every time after about 10 minutes. When my system is not overclocked it doesn’t restart. I also noticed that increasing V-Core helps like I reached about 1.3250 V-core in BIOS it’s 0.2 actual around 1.31 V real. Does anyone have this issue or suggest something.
