Wow dammit, this sound like the Painkiller himself What exactly is cooling your rig

First of all, this is a fantastic chip and runs 4,2 on air without any problems - Stoolmans former goldchip and does 5,1+ on LN2. Furthermore, Overklokk built a singel stager phase cooler into a Lian Li PCV2100APLUSII for me... There is a worklog here at XS somewhere.

"runs 4.2 on air without any problems" implies 24/7 stable, at least to me, which isn't the case. What does it run long-term Prime stable on air?

[USFORCES]

I run mine at 3.2 all the time on water, highest stable clock so far was 3842MHz, I've had it higher but not stable.

You are of course right. After initial testing on air, the chip was mounted in my PC (with singel stager) and has not been on air since. Does Prime (or is it wPrime?) at 4,4 with P5W DH Deluxe (if I remember correctly) but has not tested with P5K Deluxe, which is current MOBO. Have not benched anything since January / February.... Furthermore, although P5K Deluxe allows a higher FSB than P5W DH Deluxe, I reached a higher clock with the latter.

wow...nice fsb for the quad on that board...
may i ask what fsb that chip has been hitting on other mobo's?

480x8 (1.47V) on the Commando, 465x8 (1.43V) on the RD600. The chip just goes in the tank after 3600 unless voltage goes up in a hurry. I have found any voltage over 1.47 does not improve overclocking, even at higher or lower multipliers. It hits a brick wall around 3840, cooling does not matter. I will take 3600 with 1.4V any day though.

interesting, what type of cooling have you used?

All the qx6700's ive played with loved more voltage, sadly more voltage = way more heat. Single stage couldnt even keep it in the negatives


bingo, you should get some xeon x3220's. You would have some fun.

[DDTUNG]

For a good comparison, you guys should really post the actual Vcore under load.

Same experience here. On my QX6700 I can get 4200 MHz stable easy for benching and everyday use as well as most games that don't use more than one/two core(s).

Priming (dual orthos) 4 cores @ 3700 Mhz and 1.45V in bios (about 1.40V real) is as much heat as my Mach II GT cooler can possibly handle.

I've given it up to 1.75V in another motherboard and got I've had it up to 4.6 Ghz, but the heat is just too much for the mach II GT for anything other than max 2-3 mins of superpi...

I hope the 45 nm's are coming out sooner rather than later. The QX's are really nice overclocking chips, they respond really well to voltage as well, however they just get really, really hot when you go over 1.4V (real)

i know that a mach2gt (modded) could hold a qx6700 at 500fsb ore 4ghz at stock voltage.

Huh? Link to the numbers/screen of the person doing that please?
