QX9650 bad overclocker?

post #1 of 91
Thread Starter 
Well after having the QX9650 in my rig for about 2 hours, I have worked out that I need about 1.41v to make this chip pass 5 runs on the Linpack Burn test at 3.8Ghz!

Is it just me not doing something or is this chip not so good?

Got any suggestions?

Maybe they are bad overclockers. I've seen people sell their Extreme for cheap and bought a Q9550 E0.

What kind of WC setup do you have? Your sig rig says something about a TRUE.

The Extreme chips almost always run hot and often want more voltage than the supposedly next lower binned part. Keep in mind that there's also variation between individual chips.

If you're on air you'd get a better OC out of a Q9550. If you want to keep the chip, I suggest you invest in some good water cooling.

I doubt the cooling is going to effect the required voltage.

yeah in my opinion i would blame the nvidia board before anything. they are pretty bad quad overclockers.

i doubt theres anything wrong with your chip. there have been some who get it to 4ghz without even breaking a sweat. my chip, while slightly different to yours, gets 4ghz with a little over 1.3v ..

There must be something up...

I bought it off Core2Werd and he had screens of it at 4Ghz with 1.37v...

I doubt this board is going to make the voltage needed that much higher. Especially when it runs 1900FSB on an E8600.

actually it does. for example: i can do 5ghz at 1.68 vcore, ( thank my board) in 13c ambient temps which come to about 33c load, but in my room at 25c i cannot boot into windows at the same settings. or even get passed login screen.

EDIT: its your board. it kills these 45nms cause they were not designed for them.

Yeah, the GA-EP45-UD3P is the king of 45nm Core2 overclocking right now, but there's no SLI support. If you'd asked, I would have recommended you moved up to Core i7.
