Q6700 Oc?

mk_ln · Nov 28, 2007

hi, i recently upgraded from an E6600 to the Q6700. one thing which i noticed is that my OC is quite limited as i can only achieve 3.3GHz regardless of the vCore and other settings. is my mobo the limitation to OCing this processor? temps are fine and even lower than those of my E6600. CPU and cores1-4 are 27/40/40/36/36 respectively. while running 4 instances of prime95, the max temp for the cores is 60 and the IHS is barely above 40ºC.

thanks in advance.

I don't know about exact numbers, but I do know that the Quad core tend to OC less than dual core CPU's. 3.3 GHz is pretty good though.

Did you rule out the ram? I have read its hard to oc when all 4 dimms are populated.

hat · Nov 28, 2007

If you're not running the 2T command setting... run it

mk_ln · Nov 28, 2007

ram is already at 2T.

4 dimms being used should only stress the northbridge more, so the solution should be to increase the MCH voltage...but that doesn't seem to help.

thanks for the replies though. any more suggestions?

disable hyperpath 3 in bios. it should be in the chipset section.

also, you may want to enable SPD timings in the same section...

mk_ln · Nov 28, 2007

ya, i already have HP3 disabled and have also already tried w/ enabled SPD timings; both w/o success.

thanks for the reply

any other ideas?

volt mod?

Mussels · Nov 28, 2007

FSB strap settings? It sounds more like a mobo limit than anything else, so fiddle with any settings that may help overclock the FSB/mobo more.

by disabling hp3 and enabling spd settings you put the chipset on the loosest timigs and best strap for overclocking.

regarding the volt mod: i dont think it is a voltage issue as i have even tried with 1.6V and i still crash on the same screen after POST; the vista loading screen with the green bars moving left to right.

random murderer:
what is the max stable OC you have achieved w/ the Q6600 on the P5WDH? and what voltage was required?

thanks for the replies.

to be completely honest, i haven't even tried past 3 GHz; i'm waiting for the weather to get nice and cold. at 3GHz though, i only need 1.3 vCore and 1.65 vMCH. try upping your vMCH, quads require more MCH voltage because of the bandwidth, AND you're running 4 sticks of ram. i recommend 1.75 vMCH, or 1.85 if you have a fan on it.

hat · Nov 28, 2007

vMCH = northbridge voltage?

mk_ln · Nov 28, 2007

well, im currently at 1.65MCH. i've also tried to 1.75 and 1.85...still nothing. i've read a few posts over at XS and it appears that the mobo (specifically the 975x chipset) is the limiting factor in OCing quad cores. iirc, someone said that 'the FSB wall is around 340-380 depending on how lucky you are'.

i dont plan on swapping out this mobo anytime soon as there are still no major improvements in the newer x38 mobos to justify the price. i suppose ill just wait at least till nehalem to make my next upgrade.

thanks again for the replies.

yes, vMCH is northbridge voltage

a lot of people believe that about the 975x chipset, but it's not true. it just takes a little more work to get a respectable oc on a 975x with a quad. think of it like an oskar wu situation; it's a bitch to get it running how you want, but once you do it'll own anything else.

hat · Nov 28, 2007

Well you could try it with only 2GB of ram. If I were you I would have gotten a Q6600 and just 2GB and ran it at 3GHz. Saves money, you might loose an fps here and there. It's not really that much.

bcracer220 · Nov 28, 2007

thats a good o/c for a p965 board, ud need to get a p35 board to go higher. abit ip35-e is a very good budget option

Ketxxx · Nov 29, 2007

Updated your mobo BIOS to latest? Asus often fix OC issues in new BIOS revs even if they dont mention it. The fastest I've seen a quad on normal cooling is around 3.6GHz, so 3.3 isnt so bad.

ntdouglas · Nov 29, 2007

What about fsb termination voltage? Have you tried upping that a little?

Random Murderer · Nov 29, 2007

for everyone who disbelieves in overclocking a quad on a p5w dh, or any 975x board for that matter.

hat · Nov 29, 2007

Hm yeah with a x14 multi... engineering sample ftw

if you noticed though, the FSB is still low so i still believe that this board has a low FSB wall w/ quads.

ya, BIOS is the latest (2406). i think it was released last week or 2 weeks ago.

the board i have is a 975x board

. the p965 boards are better OCers iirc.

i thought i had posted earlier that i tried that. guess not. but ya, i have already tried that.

going to 2 GB is not really an option for me as i feel the need for 4 since i am using vista x64. i was considering, though, that it may be a better option to get 2x 2GB sticks. however, i've noticed that with higher density modules, the latency increases as well. is it noticeable though?

thanks again for all the replies and suggestions people.

4x1GB to 2x2GB has a very minor speed difference, and only noticeable in your wallet.

Must say... honestly, can people stop linking to random Q6600 OC's on this board. we know it has an FSB wall and we're looking for ways around it, not engineering samples or ones with high multis.

A few things to try:

FSB holes - example, 310 may work, 311 312 and 314 315 dont - 313 might. I did see this OCing my quad on my P965 mobo. try a few options, just in case.

PCI-E/PCI lock. if the mobo has options for PCi and PCI-E frequency, try adjusting them. raising (or lowering) them may just help out here.

voltages: you may be OCing the ram too far, or the NB too much (with 4x sticks) so raise the ram volts as well as the NB volts.

yea, i found it to be best with pci at 33.33 (obviously) and pcie at 115.
