Q6600 Overclocking Database.

[GAR]

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.

I am using the new revision wich is A1, and everymotherboard has a "HOLE" meaning it just refuses to work between certain fsb's, so it is normal, but depends on what fsb you hit it, meaning your cpu might work at 379 and wont work at 380-400 and will work at 401.

yes, lapped infinity w/ 120mm delta fan

Is this in an open or closed case? It just amazes me how your core temps are so low with only a Scythe infinity cooler on air yet doing Prime95 on all 4 cores at 3.6GHz. Just how is this possible???

3.6ghz 1.54v (8*450) 81-80-78-78Cmax temp under quadPrime stable Aircooled Thermalright Ultra Extreme. Will go higher for sure havent tried but do I really wanna lol Kinda scared of my temps hehe

Nice, what motherboard?

And is it actually stable? 30 mins P95 is just getting warmed up ;-)

and don't worry about temps, I have had overnight Prime95 passes that peaked at 92C coretemp but made it...

Is this in an open case or not? If not what case have you got?

[vincey2kr1]

Its open case at the moment with couple of fans cooling the vrms around the cpu. I will probably stick it in a antec 900 and been running 2hours on quadprime95 wich i believe is plenty of time(Electricity bill dammit! ) its on a ASus P5kdeluxe mb. I can load up windows xp and run SisoftBenchmarks, 3dmark06 at 3.8ghz but on these volts its not quadprime stable.. just scared to give her anymore juice

Same Q6600 was 3.4ghz stable on my DFI 680lt . and I'm sure missing SLI grrrrr 3dmarks just isnt the same after doing it the SLI way hehe.

Wow dude, gonna have a BBQ.

If I run 3.7 GHz, two cores, I can prime for about 10 minutes(no errors. Any 2 cores. If I try to prime 4, it fails within a second, even at an actual voltage after vdroop/vmch/vfsb mods of 1.65v, 1.625v, 1.6v, different FSBs

Could this be a PSU issue? If I am at 3.4 which is stable for 8 hours of prime and more at 1.575v actual, and turn on orthos on core 0 and 1 and another instance on cores 2 and 3 at the same time, the multimeter shows the PSU drop from 12.1 to 11.6 then spike back up to 12.1. It's a PCP&P turbocool510. I tried removing 4 HDs so I was left with one, all the PCI cards, and using less fans, but same thing. CPU limit, or try a new PSU?

Crazy good stuff there... your switch proved beneficial on the cpu clocks... that's for sure! Let's hope the rumors of SLI on X38 are true!

The temps would probably then go up by 5-7C. Perhaps the IFX-14 when it finally arrives will be great at these speeds inside a case.

Here´s a little test of my L644G099 with cold air on a P5K DLX



Tomorrow, time to go under SS

[Thasp]

Any stability past 12 seconds of use on one of four cores?

[vincey2kr1]

At what point does the cPu internal design start to throttle? I was doing some testing at 3.65ghz 1.55v, ran quadprime95 up in the 80C range perfectly fine no errors for an hour jumped into 3dmark and my FPS were terrible 20fps. Went back into bios set everything to stock ran 3mdark06 back up to 64fps..
What I'm saying is you could be running quadprime 95 stable, cpu-z shows correctly and jump into 3dmark06 and be throttled back?

[Thasp]

It is possible running 3dmark caused the graphics card to heat up. The fact that something in the case was running at 80c probably didn't help the graphics card much, which could heat up a lot(especially with crappy stock cooling), and heat the CPU up more pushing it to 100c.

I've been stable for 20 hours of prime on a single core amd, but until I upped the voltage one notch, it failed 7 minutes into fear. Games can be weird.

I need some help, I need to get another Mobo ( this one is ...... well .... )
I thought I should use the lastest chipset, so the commando is out, I def. want an SLi board so the P5K DX is out, Is it the P5b dx for me then .? I want to O'c the chip and want a board that will actually support my ram (pc8500 ) .. any suggestions ...?? thanks.

Once I get the right board, hopefully I can start posting some decent O/c results in here ..!

[Neon Biker]

Now why would the P5B Dlx be any better than the P5K? If you really want SLI and good quad-core overclocking, I think your best bet is the latest eVGA 680i revision (A1/T1).

if you want to Oc a Quad i would use a Commando its a proven product

[blade148]

thought the P5B was Sli and the P5K was ATI , will the commando handle my Ram ..? and I is an older chipset; will I have any probs ?

thanks for your repley s.

[HoriWanderFuLL]

I have run my Q6600 to 4200 Mhz 466 Fsb on my Commando Motherboard.. http://valid.x86-secret.com/show_oc?id=195644
My Memory is Gskill green heatspreader BNR version...

and it Holds Great under duel orthos although i notice no matter what i do in the bios after 10 min or so it seems to throttle back the multiplyer..

i dont know why and im not sure if its Cpu related or motherboard related...

i cant see me ditching this board in a hurry as i know its so solid..I have killed a few p5b-delux mboards trying to get where i am today with the commando..

i do run a pencil vdroop on the motherboard as it helps my Oc greatly.
Cheers Hori

[blade148]

so the commando is the way to go then .? I can't find the QVL for it and I don't suppose my ram will be listed on it any way .... but I will be able to run it @1066 ...?

thanks for your help ... I'll be buying this hopefully today ..

CPU throttling is more than likely heat since it's not speedstep kicking in.

A1 is working good for me, but the 8x multi doesnt seem to be working good for me.

[McBacker]

Hi guys!

According to Sig below do u advice me to replace my PSU?

ATM i'm running Q6600 @ 2907 with 1.315 @ Bios... is that good? I'm using a TT BT old version... should i replace the fan with a powerful one?

Thanks,

MC

[blade148]

Sorry to be off topic, But just wanted to say a BIG thanks to all those who recommended the commando to me, a VERY good stable board. Can't wait to start O/c 'ing !
