Hi,

This thread is really a continuation of the one I started here a few weeks ago. I was quite content with a clock of 3.4GHz @ 1.2000V in the BIOS, but I got a little curious as to whether I could initially boot into Windows at a higher clock and then see if it was at all stable. So I've upped the FSB to 424 to give 3.6GHz and it booted into Windows with no problems. I then decided to do 15 runs of Intel Burn Test (is that excessive?) and its passed with no problems at all.


Core voltage was at 1.192V whilst under load. Temps were 69-69-68-65 so fairly toasty but they shouldn't get anywhere near that in day to day use. I shall probably run Prime 95 blend overnight just to make sure its totally stable but I'm guessing it should be ok if it can pass IBT?
 
Not bad. I had mine at 4GHz for a while but reduced the 'clock so I could turn down the fans a bit. It's now running comfortably at 3.6GHz and there's very little noticeable difference in day to day usage.
 
That's reasonable. Pretty good given you have 8gb of ram, it's about as far as I got mine stable with 8gb.
Be aware that your p5q may be pushing suicidal voltages through the motherboard chips if it's set to auto.

I've had chips pass 15 runs of ibt then fail prime. Very frustrating.

I've manually set most of the voltages. I've left the GTL voltages on AUTO as I'm not sure what they do at the moment.

CPU Voltage: 1.2000
CPU GTL Voltage Reference (0/2): AUTO
CPU GTL Voltage Reference (1/3): AUTO
CPU PLL Voltage: 1.52
FSB Termination Voltage: 1.22
DRAM Voltage: 2.02
NB Voltage: 1.16
NB GTL Reference: AUTO
SBridge Voltage: AUTO
PCIE SATA Voltage:AUTO

I'll definetly try a Prime95 run overnight and see how it goes.
 
Happy days then :) Nicely done. Low voltage for the clock too.

Temps are pretty mental for a TRUE at that voltage, low airflow case? If not, remounting could get you 10 degrees or so. Worth it if you want to push for 3.8

I'm using a Silverstone Fortress which should have good airflow with its positive pressure design. I did think the temps were a little high especially as both the TRUE and the chip are lapped. I have tried remounting before and always got similar temps each time. Might give it another go and see if I can get them lower.
 
I've just noticed by your screen that your cpu-z is showing 2.5Ghz meaning that your chip is being throttled by your bios. so although you've got it up to 3.6ghz thats only during load. I've got the same on mine. think i posted a screen in your other topic.

EDIT : Was someone elses q9550 topic that I posted a screen in doh!

Yeah, I've still got Speedstep enabled hence it dropping to 2.5GHz when its at idle.
 
I've got my Q6600 running at 3400mhz with 16GB of ram. The overclock itself didn't require anymore tweaking than with 4GB. I've not tried taking the FSB past 400 though as I doubt the ram itself will overclock very well.
 
hmmm just found the image i was looking for and this is my temps etc

and I'm 99 per cent sure that your noctua fan is a bit better than mine since I've only got the one fan!
 
Well I tried remounting the TRUE again but it hasn't made any difference to the temps. I've actually decided that I'm going to go back to 3.4Ghz as there isn't any noticeable difference in any of the games that I own. Its nice to know that the CPU will do 3.6GHz though and on a fairly low voltage.
 
Not bad temperatures considering - although I would've expected better from a TRUE it's not likely to blow anytime soon if you want to run at 3.6 to encode a few videos or whatever :-)
 
3825MHz on Auto Voltages! But my Temp is really terrible - 47* IDLE, 78* OCCT 1H run. I need new cooler, becouse my copy of Q9550 want to get more! 4,0GHz is my dream :)
 
don't use auto particaly if you have asus mobos they like to overvolt...one annoying thing about my mobo is that my cpll I set to under 1.6volts so why the hell is it over 1.6volts o.O
 
3.5Ghz is the sweet spot on those chips

Any thing above that and then you need to chuck a load of Vcore to get more out of it.

4Ghz is achievable on quality Air (E0 stepping)
