Glad someone mentioned it, I havent had to reset the bios to get it to post again, but I am getting random stability, dont understand it, one day it will run prime for 16 hrs, the next 16 mins before failing/BSOD ???? , and this is all with absolutly nothing in the bios changed at all.

My current settings are

CPU Q6600 = 3.6ghz (400x9) 266/667 strap GTL's = 100/100/115
Mem = 1000mhz 5-5-5-15
Voltages etc, in the screenie below

Hi,
Anyone here tried to replace stock heatsinks + heatpipe with thermalright's HR-05 (on nb & sb) + HR-09 S/U on pwr section?

I've put HR-05 SLi on the southbridge with AS5, didn't try on northbridge, though. No problem in mounting it.

And what abt the heatpipe? is it detachable off the stock heatsinks?

No problem.
For ~3.5GHz vcore 1.35000V, all on def.
For 3.6GHz vcore 1.37500V, nbcore 1.35V, sbcore 1.75V, cpu vtt 1.25V
For 3.8GHz vcore 1.425V, nbcore 1.4V, sbcore 1.75V, cpu vtt 1.25V
For 4.0GHz vcore 1.49V, nbcore 1.45V, sbcore 1.8V, cpu vtt 1.3V
Any higher than this requiers even more voltage on all settings, so cause i dont need much vcore for 3.6GHz i keep it on that freq. and my ram also gets a nice round number.

Did you set GTL also or you just left it disabled?

You can take the whole hp system off if you like..i just took the sb heatpipe off and mounted the HR-05 SLi..there are screws and everything, not hard at all..

On 3.6GHz i let it disabled but for higher frequencies i need to set it.

Thanks! So there are 2 heatpipes right? I tought it's one going fm sb through base of nb to pwm..

You'll find that when using dual-core processors for most 24/7 settings GTL set to disabled works fine. With my better processors I've been as high as 540 FSB with GTL disabled and without having to resort to the use of excessive voltages. The more VCORE required and the closer the cpu is run at it's FSB wall the more important GTL becomes.

GTL settings become more of an issue for quad-core processors. But even then, depending in the individual cpu, board and BIOS version, 420-440 FSB is usually obtainable without altering GTL and still below the need of having to use excessive voltages.

Thanks Praz!

My board & Q6600 is solid the only time it fails to boot is when I messed something up & 1/2 the time just powering the PSU down & up again so the board does a full double strap setting boot sorts it out anyway. This is honestly the best board I have ever had.

This is just a suggestion & can’t hurt to try but imo your manually set GTL's are a bit out of the norm.

For the Q6600 I would try a couple of things firstly maybe a little more VTT voltage (my q6600 loves vtt) plus adjust GTL's between 0.67/0.70 or try a few points either way of Praz's cheet sheets from his edgeofstability dot com site or secondly try running with GTL's disabled/auto (you may need to set the GTL+ Buffer to week to run GTL's disabled)

Thankyou, ive not adjusted any of the voltages, I know the VTT is a bit low at 1.24v but if its stable there then I dont see any real need for anymore, however what I have done for now is set the buffers to weak and disabled GTL, its priming away quite happily ATM.

The vtt you have is not really low for the fsb you have, but rather I was giving you a couple of things to try that I know have a large impact on a quad seeing as how you said it was not 24/7 stable earlier!!.

My quad will run prime stable on low vtt but it wont keep going for days like this, it eventually ends up bending windows hence my suggestion to try a bit more.

I don't think a bit more vtt will hurt your CPU.

Anyway the main thing is you have found a groove that for now looks like it will work so fingers crossed & keep us posted.
