QX6700 Owners, please post your OCs here.

That not your qx6700 you'll be glad to hear, that's your graphics card causing problems(nv4disp.dll). What graphics card are you using?

I've had similar issues with my 8800 gtx and applications like lightwave.

Two things. Firstly with ntune or rivatuner, setting the fan speed to 85-90%, instead of auto. I found helped a lot. Suggesting to me that these BSOD are in part temperature related.

Secondly you need to possibly look at global settings for your card(3d Applications), and see if you can find the best configuration for it. In addition I believe that people have more joy with max if the viewport is set to directx, rather than opengl.

I'm presuming that you have something like an 8800 GTX or GTS?

Yeah, I am running an 8800GTX card and the even at idle the temps are fairly high at around 73C. Most of my BSOD are when running OpenGL with 3DSMax, as the screen will temporarily freeze, my sound will start looping, and eventually the system will halt with a BSOD error. The strange thing is the crashes seem much less frequent if I run my machine at the stock speeds as opposed to even a mild overclock. Very frustrating, as when I was running at 355x9 things were super snappy, but the random nv4displ.dll errors were really starting to frustrate me. I am kinda at a loss as to why I get so many nvidia related errors when running things even slightly out of spec.

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?

I just can not believe, that f***n nv4disp.dll BSOD
is from ti4200 prehistorical eon!!!!!
try google>nv4disp.dll fix etc....
VIA used to have some fix for that problem, it did work on some nonVIA based mobos.
ti4200, 5900,6600...and even 8800 have same problem?
Check nV+VIA forums for that fix.
Advice, try ti use D3D instead OGL, it is even more faster in MAX7,8,9.
regards!
