Need help OCing Q8400 - Page 3

post #21 of 23
Are you running an older BIOS?

That should be VTT. Stock is 1.2V I believe. I haven't needed to move over 1.25 for average OCs. Higher 45nm OCs need more, but for the 4.3GHz my Q9550 runs I'm using 1.36VTT as a reference.

3.7@ 1.3625 would be my personal border.. i´d even go back to 3.6 to be really safe for my feeling and you can sell it one day.
theese 100-200 mhz mean nothing .. i had a q9300 running @ 3.7 ..then 3.6.. and then i finally went back to 3.5 for 24/7 so i know it will be safe for a long time and i can sell it one day biggrin.gif

btw its on marketplace

but looks like ill sell it over another platform due i live in EU
