hey guys i'm new here but read some of the posts here and i thought you guys could help me and because most other forums don't seem to like new people and answer me!
ok so i got the q8200 stock 2.33GHz and have overclocked it to 3.15GHz so far but know it could go higher.
the temps are idle 35c and 45 load
i have the nforce 790i ultra sli motherboard so i put the FSB at 1800 from 1333 and the memory at 1600 from 1333
the voltages are:
cpu core= 1.39375 (1.368 in cpuz)
cpu FSB= 1.35
when i put the FSB up above 1800 the computer boots fine but under load it freezes
I thought C2Ds could handle 1.45v? I'd start with the guide for OCing C2D/Qs that I'm assuming has been linked. Its really pretty simple. If your FSB is already 450MHz, you might be looking at the best you can do. (More so as a quad and an NVidia chipset.)
I think your cpu voltage should be the last thing you wanna mess with. Your RAM voltages are kinda low. When you're hitting the 1066 mark i think 2.1 is a good number for your RAM voltage. You need to gradually increase your ram voltage to handle the new FSB speeds. Then you run Prime95 and see if your computer stays on. What kinda RAM do you have anyway ?
