QX6700 Owners, please post your OCs here.

[BenArcher]

Not a QX6700. but i been messing with a Q6600.

And i have to say if you want to test stability encoding movies with MeGUI into h.264. Tests very quickly

Ive had to clock back down from 3.4Ghz to 3Ghz just to get it to run for more than 2 hours (still going so hopefully dun crash) But Orthos + Prime 95 were running for hours on end before :S

[megabit]

Same here - I was happy with Prime95 running "endlessly" without errors on my QX6700 at 3.3 GHz, utntil I started real work rendering HDV in Vegas. Crahes and errors, that's what I got! Since I din't want to increase voltages any more due to the temps, I backed down to 3.1 and am very happy with it.

[megabit]

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?

[xB0n3s]

My highest OC so far was 3.2 GHz (12x267) stable I think. I've run SuperPI 1m,2M,4M,8M,16M, Aquamark 3.0, all 3DMarks except 2001 using the default bios which came with the board (701 I guess). Now my question is what bios would give me higher OC (I'm using an an Scythe Infinity with a 120mm fan on it)?

Air results

Tuniq Tower 120 with two Antec Stealth fans on either side to assist with air flow in 23C ambients.

Max CoreTemps after around 8minutes of Prime95 Small FFT test.

Core#0 65C
Core#1 65C
Core#2 61C
Core#3 61C


8 hours Prime95 blend stable at 3Ghz with 1.248v / 1.208v (windows Idle / Prime vdroop)

[RLM]

Swiftech ultra now installed with w/c on the cpu and northbridge.

A quick prime test on blend. CPU 315x11 (3465mhz) 1.45v in bios Memory 2:3 950 mhz 4-4-4-12-42 2.2v.

Tried 400x9, but core 3 is weak and I need 1.55v in bios to get stable.

Ambient 30c ish

Note: for some messed up reason coretemp shows I have a Q6800. Yesterday it was a Q6900

Well go figure, after running @ 3.41 for 30mins, i lost a core. Im guessing its my room temp, as its 7* warmer in here then it was 1 week ago. Stable so far @ 3.33GHz.

Max Temps:
Core#0 69*C
Core#1 65*C
Core#2 69*C
Core#3 65*C

Hey guys. Great thread. One request. Don;t make reference to your sig, cos in time to come, when peeps are looking in on this thread, they won't know wtf your talking about when your sig is changed.

Oh and all you 266FSB huggers... crank it UP!!!!! even if you have to drop the multi, you'll get better perf.

[Severance]

running a qx6700 on badaxe 2. 333x12 vcore=1.55 . This chip dies at 380+ fsb. I was using x6800 yesterday at 460fsb no problems. 333x12 200\667 4.3.4.8 seems to be best performance for me. System on chilled liquid cooling.

lower fsb = lower strap = better performance (mostly for 680i and RD600 people)

[STeel Chicken]

still working out the max OC of the chip...but my biggest issue is the heat load. Running @ 1.4v with all cores running they'll get to 90+ real quick, on the zalman LED. I use TAT for 2 cores and quatro for the other two. Yikes! Air cooling just won't cut it. Got a nice h20 system just need to install it. Petra has some great customer service

board will do 380fsb pretty reliably in the testing ive done so far.
CPU will do one mult over on stock V, and one more with just a little more juice.

not going to spend much more time trying to eek out every bit of performance on air, but so far seems like a very nice chip.

[megabit]

I'm having problems with the temps of my QX6700, as well. In fact, I had to revert from Scythe Ninja RevB to the stock cooler, which does much better! I RMA'd the Ninja, and will be giving next try when a new one arrives.

Anyway, for the 24/7 work, I'd like to keep the power savings setting in BIOS (SpeedStep, C1) so that the CPU only kicks when needed (right now it's working at some 1.14V and 1.8GHz, with fans almost stopped; when I do some HDV rendering it goes up to 3.10 GHz and the temps never exceed 75C). FSB at 310 MHz is the max I can get without increasing the Vcore from Auto (which is the only setting possible when using C1/SpeedStep). I have overclocked the RAM to some 466 MHz (5:5:5:18) at 2.20V (Geil DDR2-800). What I'd like to do is increase the FSB a bit higher, so that the overall system performance is better - if the CPU temps will get too high, I can go down with the multiplier to 9 or 8 (currently 10).

My question is: which voltage settings (apart from RAM already at 2.20, and Vcore that I need to leave at Auto for the above reasons) should I change in order to assure stability with FSB = 333 or higher?

[Severance]

Hope i dont get trouble for asking this here but i have one problem when i overclock over 3.8 i have problems with video. Playing a divx or xvid or dvd playback and dots appear on screen. 3D gaming all is fine only video playback and dots appear. pci set to 101mhz in bios. Seems if i bring it up to 105mhz the dots get worse so that may have something to do with it. Im using 2 ati 1950 crossfire. did not have this problem with my x800 only came when i swapped it for this qx6700 chip. Did a format but no change.

I'm testing my new qx6700 on p5wdh, p5bdlx and commando.
But how do you guys get prime to run 4 threads (and thus stress all cores)?
What version are the guys with the prime screenshots above running?
I never get more then 1 thread!

what board is that?

I wouldnt go that far, as i dont like anything over 70* Defently install the H20 system, i wana see the results!

Nice, and sux that your scythe is messed up, mine runs perfect. As for the FSB, good question, when i get to 333, it wont boot. And i have tried different volts on the FSB, with no luck.

P5B Deluxe Wifi/AP
CPU watercooled and very hot

As far as I know it's one of the best clocking boxed QX6700 in europe with watercooling...

And I don't need it anymore -> to much power, a normal core2duo cpu has enough power for games. So pm me when you're looking for a good qx6700 (bill from 15.1.2007)

Twords the end of the year, you will be using a good amount of those 4 cores. Just saying, only reason i built this system is for longitivity. You will lose money on a highend purchase, IMHO i would keep it. Supreme commander uses quad cores, not fully but they do use them. Valve is even using quad cores for their next game, and possibly HL2:Ep2. Its your choice, but i just feel future proofing is the ultimate, esp with a cpu.

BTW what clocks did you get out of the quad?

not :p pedro roach has one off the beter qaud's in his hands

[Entsafter]

Pedro isn't a normal user... pretested hardware from the manufacturer doesn't count, same as ES cpus... they are not comparable to normal boxed/retail CPUs...

Excatly;
My best OC so far is 3300 (11x300 1.35v) mem timings 4-4-4-12 (2.1v) all done on air. My question is can I go any further on air (using 0901 BIOS)?

Why not ES CPU's?

lower fsb = lower strap = better performance (mostly for 680i and RD600 people)

Ya. Boot at low... and then hike up afterwards with clockgen?? Quads like the higher FSB do they not.
