Core 2 Q9450 Overclock help

post #1 of 7
Thread Starter 
I have a watercooled Q9450, I've overclocked it from 2.66 ghz to 3.40 ghz.

For some reason it has some amount of instability. I've mostly fixed it, I wait a few minutes after boot up and it usually helps.

What I can't figure out is why I can't overclock above 3.4, is there an actual barrier? I do have comfortable temps, consistantly just below 70 degrees C under load.

Should I not even bother? Every time I try to go above 3.4, even by as little as 25 added to the FSB clock it becomes irreperably unstable.

I overclock via bios.

You're going to have to give us your BIOS settings.

70C at 3.4 is not good at all, what kind of loop do you have set up, and what are you loading it with?

70C at 3.4 with a custom loop is way too hot. Something ain't right.

Just to throw it out there, I had the xfx 780i mobo and it was HORRIBLE for overclocking. I couldnt' ever get past 3.8ghz with my q9450. I actually bought an ep45-ud3p off someone on here and now can take my proc over 4.0ghz with ease and still have acceptable temps.

The northbridge on the 780i just gets way too bloody hot.
