Q9450 OC / Temps / Settings

[trt740]

That seems to be the problem with these quad 45nm chips. The need for relatively low vcore (mine needed 1.298 to be 3.6GHz P95 small ffts) but a ton of NB and VTT to get it blend stable.

is vtt the same as PLL

is vtt the same as PLL

also I'm testing a q9450 that is supposed to do 3.88ghz

Hi all. Needed a new system and ended up going with the 9450 and P5Q. My new gear is below. I'd like to offer a special thanks to those who've gone before me here... cob, luci5r...

Prime stable at least 8 hours... but
even at only 1.33v, I'm hitting mid 70s on all cores with my TRUE...

Does this sound like a remount is needed or a hot chip?

Good show there mate! Looks awesome.
Made a couple of suggestions in your BIOS Settings, in case you'd like to try.

As far as temperatures - during Stress Testing (100% on all 4 cores), most on air rigs are hitting 70 ... mine does too. I don't think that's a big problem.
