QX6700 Owners, please post your OCs here.

QX6700, 8x450 on the abit QuadGT at 1.40V.

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.

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

Early air cooling test.

Mobo: BFG 680i P24
Cooling: Tuniq Tower 120 with two additional fans either side
CPU speed: 3000Mhz 250x12
Stablity test: Prime95 v25.1 10mins in so far
Max CoreTemps under SmallFFT test: 67C
Vcore idle: 1.24
Vcore load: 1.20
Ambient temps: 26C

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?

[BarkerD]

QX6700, Asus P5WDH, 2GB TeamXtreme D9GMH, Watercooled (PA120.3 rad, 1/2", Swiftec 655 pump)

3.5GHz - 48degC idle and 65degC load after 8 hours prime

[Speederlander]

Currently now priming small 8K fft @ 2.66 GHz with 1.14 vcore under load.

[aspstein]

This was a test i did i while ago.

Cooling was my overklokk singlestager which doesnt get very cold but holds load pretty well.
Temp in bios is about +10C lol

Max fsb and clock


100% stable speed


Didnt do any screens of loadtesting @ 4,14GHz, but I thought it wasnt to bad for an singlestager.

See sig. Runs fine in prime95 for a few hours. Ima test it more tommarow to see if it crashes. So far runs fine in oblivion and FEAR. These are GREAT chips.

What are your temperatures? I used to have a Ninja Plus revB, but it must have been flawn as CoreTemp showed up to 90C at full load! I reverted to the stock cooler for time being, which gives me some 20C lower temps. However, I'd like to install a better CPU cooling - is you Scythe OK?
