*Official Retail G0 Q6600 Overclocking Thread*

[~aoe~]

Does anyone have recent results with a Q6700 yet? I know it's an old model, but I remember a few saying they would try one since the prices have dropped. I'm also considering getting one as the 10x multi is very appealing. 400x10 sounds achievable on water .

Instead of explaining my cooling setup; here's an awesome picture (joking, lol):

Lapped w/ 21-22C ambients (explaining our difference in temps since yours is 6C higher)

I have the G.Skill F2-8000CL5D, but I'm only running it at 800mhz and 4-4-4-12 timings right now. I haven't tested the bandwidth on that compared to 1000mhz yet. Also, it seems like the jump in voltage/temps on our VID from 3.6-3.7ghz to 3.8+ is more than it's worth...but then again I plan to run my setup all day for gaming so to each his own I guess.

I didn't do anything special to get real temp working.


Oh before I forget, that was one nice lapping Pacha!! I think that beats the lap...dance..I got at club la vela, lmao! Care to explain the method you used with the glass/paper?

So I re-checked my ambient temps and they are at 27c, so it isn't that far off with my idle setting at 40c. I have a new pump and the D-Tek fusion coming in which should drop my temps a few degrees. I do use my comp 24/7, but my temps rarely go above 55c even with the added voltage. I just don't use anything that pushes my system to the level that OCCT does, even video conversion and gaming don't exceed 55c. I am currently running some benches to see how much of an improvement the extra 220Mhz+ gives me. If I find it only gives me 5-10% more I may drop it back to 3.6Ghz, but we will see. I kinda like the sound of 3.8Ghz vs. 3.6Ghz, makes me feel like the investment is paying off.

As far as you cooling, it is really hard to see in that pic, but I am guessing you are on air cooling, so getting those temps are really good for that.

Anyway, it seems like you have a pretty sweet setup and it's nice to see someone else's results with the same batch.
Thanks again for the post,

I've got my Q6600, it's L745B108 batch, anyone heard something about it? Haven't got rest of my hardware yet so can't test it.

The L745's have the best chips ive seen, though im sure there are bad ones amongst them.

[jb-]

Yea I'm on air w/ fans in the locations near those arrows. Unfortunately I'm still running at those same settings posted before after messing with the memory all night. I can't get my memory to run at 1000+mhz and provide better bandwidth than what I'm getting now at 800mhz and tight timings. On the thread for this memory people are posting some good results, but mine are apparentally bad sticks. I can't get anything over 1000mhz stable, and even when I do the bandwidth is the same as now. I'm switching back to Vista 64bit later and plan to finish this OC up before Age of Conan is released in a week. :P Post your results after getting your new stuff utnorris!

[Utnorris]

Have you tried loosing your timinings to 5-5-5-15-60? I have no problem running at 1080Mhz when I am at 450x8. I can only run at 1021Mhz at 425x9 due to my memory wanting the 333Mhz strap. Anyway, you have some really good results with air cooling.

By the way, according to Eversest benchmark, I am at 9641 - 8192 - 8644 - 51.8 when I run at 1080Mhz, not too bad.

Anyway, keep posting your results,

whats the lowest vcore an average VID chip should be able to run ar stock 2.4 speeds? is 1.14 real pretty good?

[Unoid]

so it appears with 1.325vid chips 3.6ghz is the max and requires 1.5Vcore maybe more. Ouch

[Pacha]

Unless you madely overclock your memory, you use +4Gb RAM or your FSB is above 450MHz, usually, you won't need to increase vNB

Those voltages on the NB are clearly not appropriate for only the CPU
Also, at those frequencies, VTT above 1.30v won't help you as you noted

Many people still bump crazy voltages every where when they don't know what to do or what's holding them.
In your case, it is clearly the vcore limiting you. These L8x steppings act like B3 and early G0 chips. For a Q6600, I won't hesitate bumping 1.53v + loadline calibration if your temperature permits it. Intel specs are 1.50v, so with 10% margin on 65nm chips you can go to 1.65v. Usually, you'll be limited to 1.53-1.55 with heat

I never heard of any Kentsfield reported deaths at those voltages and I ran my B3 at 1.53v for few months too at 3.6GHz

edit: I noted you have a commando, it is a very bad overclocker of quadcores and stability near and above 400FSB is a random dream

I agree. But temps finally raise up if I set too much voltage and I'm not even sure I'll reach 3.5 with a lot of vcore, as adding 0.05V directly doesn't give me any more second of stability at 3.4.
I must say that I forgot my Commando is a very bad board for quad, but seeing the others' results, mine are a mix of Commando's limitation and the poor CPU overclocking qualities. If I buy a P35 mobo or such I'll certainly be limited at 3.4 like others, and I'm not going to buy a new CPU and a new mobo right now. I'll wait a bit for that; quite disappointing anyway.

Bought a brand new 2008 G0 Q6600 (which came in a dark blue box), FPO L806A692 with a VID of 1.325V It was a rubbish clocker and needed 1.45V to get 3.2Ghz OCCT stable.
But I found a G0 on Ebay FPO L730B292 and 1.2625V VID (which came in a LIGHT blue box). This one does 3.4GHz at default volts, perfectly stable
Needs 1.34V to do 3.6 Gz but maybe able to reduce that by tinkering with VTT and GTL reference voltages.

Did my first Overclock today and was pleased to find it stable. my Q6600 now running at 3.0ghz prime95 stable and 1h OCCT stable, Vcore: 1.168, Idle: 36, 36,34, 32c Load: 52, 52, 47, 45c.

Now that i have some time over the weekend
, ill try to push for 3.4 ghz.

Whats you're VID? sounds like you can push 3.6 on air at 1.4v

[Utnorris]

Just from what I have read here, getting 3.0Ghz is not a problem with the Q6600, even the B3 stepping can do it. Getting 3.6Ghz usually requires a substantial increase in vcore, most reporting above 1.4v and this is with a vid of 1.27v or lower. I would imagine with a higher vid you would need at least 1.45v or higher. My vid is 1.265v and I need 1.47v to be OCCT stable. Although the vid isn't the only thing to determine how high you can overclock it is usually a good indicator.

same here, 333 on the FSB, 3.06Ghz, stock cooler, idles at ~32, under load is high 40's.

Got my Q6600 yesterday. And I´m impressed! Both at how cool it runs and how good it clocks. Before I had dualcore 2160 and e8400. I sure liked both of them but it is something special to run a Quad

I never thought that 4 cores could run this cool. My new Quad runs cooler at 3,6 Ghz than my 2160 did at 3,6 ghz without IHS. I had some trouble at first, getting a good OC but then I saw that I had LoadLine calibration disabled. When I enabled it, it became a complete different story.

3,0 Ghz was a of course a simple task, 3.4 too. At 3.6 I had to finetune some setting to get stable, I raised Fsb termination to 1.4 and vcore to 1.4. My coretemps didnt get over 70 with absolute full load at all 4 cores (S&M cpu (fpu). I started to play a little with 3.8 Ghz but had some trouble getting stable. I dont think this is going to be a problem, just need some more testing.

I absolutley Love this cpu, Q6600 still rules

I think this chip is good for at least 3.8 ghz on air.

[fng77]

Maximus likes this cpu too. 480*6 ok, 490*6 needs more work. I dont know if thats considerd good on these chips, I´m anyway

[Cob]

Anything over 480mhz is good with the quads.

[865pe]

%75 2008 Q6600 all VİD > 1.3000v +

[fng77]

Anything over 480mhz is good with the quads.

Great! Then I will spend my Saturday evening trying to get stable at 490 500 would be really sweet, but my NB is already quite varm at 480, could use some water at this task.

[aussie-revhead]

My L737B has a vid of 1.2125v , it is stable at 3200 with 1.2425v and 3600 at 1.3925v but I have been trying for days to get it even benchable at 4GHz . I achieved this today , I ran 3D06 at 4005MHz along with wprime 32 and 1024 but it took near 1.7v to do it and its only just stable enough for that . Temps were sizzling too , up to 86 while running 1024 so I wont be doing that too often. Thats with a lapped Fuzion , triple rad and IHS lapped too .

nice results.
what's your cpu batch? and VID?

[fng77]

nice results.

Now I´m confused. I thought that the VID was a fixed value that didn change.

When I first checked the vid it was 1.300 which is alright I think. But I got amazed how good this chip clocked with low voltiges.

Now I just checked again just to make sure, and the VID value is all of a sudden 1.1625v, which is almost to good to be true. As I said before, I didn now this valu coulde change. Second thougt, perhaps the first vid was somehow a leftover from my e2160, because the vid changed after I rebooted a couple of times.

in that case I´m the worlds most happy

About Batch, I dont now which number it is: L728A825 or E10342-00 or another?

[fng77]

Best vid I have ever seen.

[jonny_ftm]

This should be really pinned as a sticky. At least 3 posts a day with people claiming: MY GOD, I GOT THE BEST VID: 1.1xv
Sorry to be some but I even noted that no one no longer bother to answer those people

VID we talk a bout is at default CPU speed, C1E and Speedstep/ESIT disabled and lowest is 1.20v

Damn. I didn´t know that. I apologize for myself and all the other ignorant people here, that have done this misstake before.

Í will spend this evening standing in the corner. I really thought this was my chance to be speacial...

[manyga]

Best vid I have ever seen.

The C1E or SPEEDSTEP activate, not true vid!!
