Q6600 Overclocking Database.

It is worth it... just take your time while lapping and read up on the topic... you'll be fine. Be sure to report back to us.

Right, well ive just stuck an order in for a Q6600 myself, and i have a D-tek fusion sat here waiting to meet it .Ive been keeping an eye on this thread to see what ppl are getting - would be really pleased with 3.5ghz myself.

Hey Mike, good luck on the OC, atleast 1.45v will be needed for 3.5ghz, im sure you will reach it tho.

[MikeMK]

Thanks Gar - I'll report back here when i have it all up and running. I should be setting up my loop on Sunday, so I should have some results early next week

[RADCOM]

Im loving quad core, i dont know if its all in my head but windows seems to be running much smoother now.....but then again it could be all in my head?

lol just seeing the 4 cpu in taskmanager works for me and that was only on my dual Xeons with hyperthreading when we see 8 we will give up sex

[Ad1tya]

^^ Talk for yourself :P.
Ill never give up sex, not even if you give me a 16 Core monster! Lol..

Anyways, Whats the best batch of Retail Q66's people have seen till now?

[Brian y.]

Definitely need to apply better cooling........Using the P5B it hits a wall at 425FSB

Right now it's been folding on all cores @3330MHz 1.45v for two days.

[IMG][/IMG]
I know, the temps are a bit high....


I'm hoping that my P5K will fair better when I get time to set it up for some DICE runs.

Forgive the X3220 result, but I thought it might be of value, as it is the same thing as a Q6600, and clocking exactly the same EDIT: a bit better than the Q6600 I posted earlier about in the P5K-DL

Xeon 3220 L640F057 pack date 3/1/07
P5K Deluxe BIOS 311
Ultra-120 Extreme
Thermaltake Toughpower 750w

3456MHz @ 1.5250v bios (damper on) = 346 watts system 8K Prime95
(droops to 1.480v in Prime95)

EDIT: NEW RESULT

3546MHz @ 1.5625v bios (damper on) = 382 watts system 8K Prime95
(droops to 1.520v in Prime95)

12 hour stable tested:[/COLOR]

I think all quad IHS are as bent as a banana aren't they ...?? mine is ! would def. be worth lapping it in. I'll probably do mine, but I'm having probelms with mine,

I started a new thread would appreciate comments .... pls.

That's interesting, I have a X3220 L640F058 (pack date 3/1/07 as well).

My results are back a page (also in my sig)... http://www.xtremesystems.org/forums/...=142430&page=5

How about that?! Brothers!

I have now got mine to 3528Mhz @ 1.5625v, but the going is tough...

Does yours have a 9 to 11C difference between Core 0 and core 3 like mine?

That's awesome for air cooling.

Mine has 3-4 degrees difference between cores... but I'm water cooling. There has been a lot of discussion on the water cooling forums about how to even out temps... it seems by tweaking the mounting tension on each of the four mounting posts, you can even out the cores. You need to be able to monitor the temps under load while turning each screw slightly to see what effect it has on the temps. This assumes your heat sink uses screws and that they can be adjusted while the system is running.

[blade148]

can i just ask, which temp program do you believe .? asus probe says 33c and temp 0.95 reads about 60 ish per core ... ( on load at stock settings. ) Can't believe Asus probe, but would of thought there software should be good for there own boards ..!

asus probe is good till the temps reach 60C after that it's way off. use core temp or everest.

is it? I have so few reference points to compare to. But if you say so that makes me happier. Within 2% percent of what I used to do on dual core is awesome - thanks Ultra-120 Extreme!

I can't do that - the screws on the Ultra-120 have springs on them that do the work, so all are fully screwed in. I have put some spacers in there and remounted several times with consistent results, so i am leaning toward thinking I have one of those imperfect IHS that could use a lap job.. oh well, it clocks well, so thats all that matters.

[graysky]

RMClock is the sh*t. Just google it and use it.

[MikeMK]

Right, my Q6600 just arrived. Its an L645F197 - any one have any ideas on how this thing behaves? Hopefully its a good one!

[crossg]

Nice! That just made up my mind on the P5K deluxe. As soon as they are available here I will rush out and get one, then my current board can have my C2D E6600 back.

Vcore at 1.55 in Bios,working on lowering it,currently priming at 1.5375.Also will be upgrading WC'ing within the next few days so will hopefully get those temps down,too damn hot for my liking chaps!

Well, it just got 100MHz better (3550)

I think I am at the limit now though, 3564 and over explode, and my damn uneven IHS means my temps on Core 0&1 are 6C worse than the Q6600, meaning I am running out of room on heat, even though I could go a couple more notches on voltage.

Oh well, I am happy.

seems ive run into a fsb hole on my board, from 370-400 seems to be a hole.......anyone else with this board and a Q6600?

[graysky]

I will add everyones results, please provide the following information, a cpu-z screenshot, voltage used under 100% load, and what stability tests it has passed.

I have a vdroop modified P5B-Del; voltage load = voltage idle = 1.232v. The BIOS voltage is 1.2375v. It is >6h 2x othos stable. I stopped running it after 6 h.

Cooling is a lapped Ultra-120 Extreme and the IHS on the CPU is also lapped.

@IntheWilderness... what motherboard?

Pardon me if i'm wrong and telling you something you already know. I do believe first revisions of the motherboard you are using had issues when trying to overclock quad cores and you *should* have the option to RMA the board for a later revision.
