Quad Core OC Database

[FabricioGS]

My mission was 4Ghz 24/7, but if i must believe you all, that is going to be none problem .

UPDATE:

4Ghz, 32°C idle (1.448Vcore) and 52°C stressed (1.412Vcore), i think i've got one hell of a Q6600 .

You think?

[Prodigys]

You think?

Now I just know, and don't think .

Sooooooo.. the topic is death? Abandoned by it's creator?

Sooooooo.. the topic is death? Abandoned by it's creator?

Seems so...I PM'd him and he wrote me back saying he'd try to do better...that was almost two months ago!

Ok after tweaking I got it stable at 3.9 on air.

[Leeghoofd]

Ya watercooling setup is asking for a bigger or extra rad I think Karl...

[karl_eller]

Yeah unfortunatly there isn't really too much I can do about that. Isn't enough room to fit another rad (aside from MAYBE an MCR120), and upgrading to a PA120.3 isn't worthwhile. Maybe some time later this year if/when I get two of ATI's new R700 GPUs I might go dual-loop in a new case or something.

got my q6600 installed and running @ 3.6Ghz at 1.33V, will keep testing to find the max oc. just wondering whats the max volt for 24/7 with watercooling?

[jonny_ftm]

got my q6600 installed and running @ 3.6Ghz at 1.33V, will keep testing to find the max oc. just wondering whats the max volt for 24/7 with watercooling?

My batch also did 3.6GHz at 1.33v
I needed 1.43v for 3.8GHz though, and it runs hot on my loop

Every CPU is different, I'd say, the Kentsfield showed to be a robust chip, we have now enough time to say it. No deterioration like the 45nm. So, pump it until your water can't give you better than 65-68°C on the cores while loading with small FFT the 4 cores. There's your limit. Usually they will top at 3.8GHz, if you're lucky, 3.9-4GHz (hey, must be very very very lucky)

Intel specs for the Kentsfield are 1.50v. With people using loadline calibration and vdroop mods, account for overshooting voltage too. So, 1.45v should be really an extremely safe limit. 1.5-1.55v, if temperatures are within range, you should run fine for some years, maybe

thanks for the reply Jonny, I have tried 1.5v @ 4Ghz but cant prime it as my loop gets really hot (68°C under full load), im upgrading my radiator next week and lap the IHS, hope i can get a better result

Hi,
After my B3, a L734 G0 doing 3.6GHz at 1.42v, I got a new G0 L740B126



It is with open window for some minutes. At 24°C ambiant, it is as hot on 2 cores as with my previous L734A at same 3.6GHz but with 1.424 real vcore instead of 1.334v forr this one

So, despite the lower vcore, it heats quiet the same as a per clock reference. The delta between cores is up to 7°C usually. I'll try to reseat in few days with some MX-2, then I'll try a vertical mount of my WB. If nothing do it, I could lap it

See my signature for all hardware setup

The most interesting, is my P5B deluxe stable at that memory OC, timings and just 1.25v on the NB. And hey, it is 266 strap. The X38 is a best clocker, but couldn't clock this at 266 strap on a qaudcore and furthermore with 1.25v.

I got a really good P965, even if it is a C1 revision

Got a new board and HSF. Have not run prime yet. Using OCCT as initial test for stability. When i get my chipset actively cooled i will run prime95 overnight.

For now:

OK I mounted a 40mm fan on the chipset and ran prime95 for an hour. I'm disappointed the fan did not make a huge difference. This thing is like double the thickness of your average 40mm fan. LAME! Looks like i'm going to have to replace the chipset cooler all together. Gotta do something about the PWM temps as well. Anyway.... Here's an hour of prime.

Finnaly I found this Q6600....with 1.3volt set in Bios with vdrop mod...Thermalright with 2 Fan SilverStone FM 121

With just cold ambients, all inside my case (18ºC) I can do this:





This Q6600 + DQ6 has a FSB wall around 470Mhz. This same Q6600 can prime @ 510Mhz FSB on P5E3

Max stable 3dmark (X38-DQ6's fsb wall hold me back):
Note: C1E activated



This CPU is a beast. I can run 3dmark06 at this setting with only 1.58v, but sometimes it would crash on CPU test. The sad part is when I discovered that this mobo has bigger Vcore intervals after 1.60v. A pic to make you understand:



Well, I'm happy with this piece of hardware

Rbs.


PS: P5K Deluxe will never do that. Max 3dmark06 stable was 4050Mhz at same conditions.

The Q9450 in a X38 or P35 chipset should do well. But for SLI users that are limited to Nvidia chipsets that can't really lean on the FSB with a quad core, the Q6600 is still the better bet for overclockers. The 8x multi of the Q9450 really hurts it on Nvidia chipsets

The best I could do with a Q9450 on my board is 475Mhz FSB (3.8Ghz). It's really frustrating when you know that the chip has plenty more in the tank, but your board simply cannot push your chip.
