Retail Q9650 Overclocking Thread

[LennyRhys]

nice chip. mine does the same 4.2 @ 1.29. Curious if you've tried for higher clocks and at what voltage. i've been happy at 4.2 with a pretty low voltage so i haven't touched it for months, but wondering if you've tried higher clocks with around 1.35v.

My chip is also very similar - I currently have 4.3GHz stable at 1.3625 in bios, 1.368 load in CPU-Z. It all depends on the voltage curve of your chip... some chips that do up to 4.2GHz below 1.3v aren't necessarily good with low volts beyond that frequency.

I am trying to get 4.3GHz stable at 1.35 and i think it's possible but it will require a lot of work with clock skews and GTL voltages. Most reasonably good Q9650s hit 4.3GHz around the 1.35v mark, give or take.

Hello,

I tried to overclock at a higher level than 4200MHz.
Unfortunately it was necessary to increase vfsb, vcore and vnb and I'm quite afraid of it. ^_^
Moreover I'm trying to overlock another cpu at the same time.(E7400 @9*445 for the moment @1.288v )
