1 QX6700, 2 Days, 3 Motherboards

Hey All,

I had some free time this weekend(wife and kids went to her moms) and a brand new QX6700. I have a an Abit quadGT that I bought and then an hour later the DFI965 was in stock so I bought that too. I also used the wife's Asus P5b premium. I thought I would share my results from Quadcore land.

I used the same components and same OS for all boards with the goal of find ing the hghest FSB for my quadcore.

Vista64 Ultimate and I did a fresh install on each board(Vista installs in about 11 minutes BTW from my flash drive)
4x1gb mushkin redlines pc1000
3x 74gig raptors in raid zero
and 1 750 gig seagate
8800gtx


DFi965s

The max fsb I could reach was 405. 406fsb blue screened not mater bios settings or voltages I tried. I lowered my multi to 6 and and set the fsb to 400 which is lower then the default speed of my chip and I still got blue screens if I tried to run prime95. This board runs fine with my X6800 up to 490fsb.



P5b Premium

The max fsb I could reach was 422fsb. This board runs 24/7 7x525 with my x6800 in my wifes rig.

Quad GT


The max fsb I could reach was 447fsb. This board also booted the highest for quick super pi run at 3825ghz. This board seems to handle my quad the best with no funky reboot issues.

These are my results and not scientific so no flames I am just sharing my results! Oh, and one more thing Quadcores run Hot!!!!!!!!

Abit seems to have their stuff together so far with the Quad Core chips.

Thanks for these results, Bootsy. Might you have a P5B Deluxe close by that you could test? I know the P5B Premium is supposed to be the Vista-Ready equivalent of the P5B Deluxe, but 422fsb seems a bit low for something based on the P5B Deluxe, so the Deluxe might make a better showing.

Was Quad GT the best rock-solid stable FSB? I assume all those max FSBs are considerably unstable under long term prime95 or orthos. Where do the stable FSBs fall on those boards?

unfortunalty I dont but to your point the P5b premium doesn't have the best voltage options.

Yes the Quadgt was the most stable 8x440 6 hours prime stable. About 415x4 hours prime stable for the pb5 premium . On the dfi the most I could get prime stable for even a couple of hours was 380fsb. I just didnt have enough time to run 8-10 hour primes as the wife's machine had to be back in working order:)

what temps are you pulling at that overclock on qx6700
also what volts, thanks

edit :sorry i just looked at pics and i can see now

you need to adjust the GTL ref on the DFI (for quad core)

nice results btw :)

Thanks, and been there done that:) The DFi wouldnt budge off 380 fsb until I tried all the different GTL strength settings.
