*Official Retail G0 Q6600 Overclocking Thread*

[Prodigys]

Anybody got a better Q6600 G0 then me ?

He does 4Ghz Prime95/Orthos stable on 1.384Vcore, max suicide on that Vcore is 4185Mhz ... Batch is L737B242 with a VID of 1.22500 ....
Wafer number is in the 60-70's ...

I'm just curiuos becuase this thing almost overclocks like a 45nm cpu ... .

Nice cpu there , from your sig:

4.212Ghz (468 x 9 | 1.486Vcore, 57°C stressed) [TESTING]

Is this the highest you have seen so far ? What mobo are you testing on atm ?

Hi,

I'm somewhat noob to OC. I was planning to get Q9450 till I found out it's not really that faster than Q6600 so I decided to save like $160 and bought Q6600 from Microcenter. it's L740bxxx don't exactly remember as I'm at work now. I was able to OC it to 3.15 but can't get any higher than that. I got Asus P5E-VM HDMI and it's MATX but some people were able to hit 500+FSB with this mobo. Ram is G.Skill 2x2GB PC2 8000. I used same setting as guy who was able to get 500+FSB in BIOS. If I drop Multi to below 9 and keep it below 3.15Ghz, I can get pass 400+FSB mark which I haven't really tried to push hard. VID is 1.3125 and if I bump vcore to 1.5, it would last little longer for prime but eventually just restarts without any error. I can't provide settings in BIOS as I'm at work now but my question is that is it safe to assume that I hit wall with my CPU since I can go higher FSB but can't OC higher than 3.15Ghz? Also would it effect OC if I had PentiumD 820 and just replaced with Q6600 without reinstall of OS?

So for I can hit 468 x 9, but in the mean time on a lower Vcore then that, that first run was with some extra V to be sure.
Mobo is a P5E that is half dead ... Ordered a DFI P35-TR2s that I'm getting this week hopefully. Max FSB on this mobo with quad is 483, tested it with 5 quads so it's going to the RMA as soon as I get my DFI.

Cant believe my friend just got his Q6600 and he was not planning to overclock, and ques what VID he got the lowest i ever saw...1.1000

Doe EIST of dergelijke maar eens uit dan krijg je de echte te zien.
Ik kreeg ook 1.15 te zien met EIST en die andere dingen aan...

Yeah, put it under load and the see what the VID is.

Any Prime95 -blend test- + 3dMark06 with CPU-z screen shot running for at least 6 hours?

I can't give you any screenshot with a longer stresstime then 10 min above 3.825Ghz becuase my mobo is half dead... As soon as I go higher then 430 FSB he won't get stable. I just know the quad is stable, he does 3DMark2006 2 loops on 4059Mhz with 1.384Vcore, 3rd loop is freeze becuase mobo is doing hard then...

I did Prime95 + R@H + COD4 on 3825Mhz with 1.342Vcore for 5 hours without a problem, but when I go for the mobo higher then this FSB I can't get it stable.

Also the mobo has a FSB wall on 445 FSB with all the CPU's i've had lying here (5-6 cpu's). I can do what I want it doesnt matter.

(In the mean time, he is under the cascade by a friend of me. He does boot 520 x 9 on 1.72Vcore and he's still testing )

I thought there was nothing that could change the VID shown by Core Temp. I thought that was something the "came" with the processor.

In any case, you better be getting the batch of that CPU for us... let the hunt begin!

Too bad it doesn't have the temps of the 45nm Good one mate...

Go go Limburg !!

EIST enabled can have some fluctuation on the VID but dunno if it's board or Coretemp version related....

yeah, i know i've seen coretemp report my VID at 1.100 before, but the VID is actually 1.225 (L737B...). Not sure why

Wrong VID from Coretemp 97.1


Correct VID from Coretemp 96.1

Here's my setup, its not totally tweaked yet still got more to go
duno why CPUz has a messed up core speed lol

did you disable speed-stepping in the BIOS?

[Prodigys]

It isn't much different then a 45nm I think .
48°C stressed on 4Ghz and 1.384V .

EDIT:

Vanwaar ben je zelf ergens ? Ben wel eens geintresseerd in een DOC Limburg team .
Wat hardware uitruilen etc ... Q6600 is momenteel ook bij een vriend onder de LN2, tijd voor world record te breken van Q6600 Superpi 1M en world record van hoogste speed .

Here is 3.8 on air running WCG 24/7. P5K Premium, 2x1gb Team Xtreem, TRUE with 2 Yate Loon medium speed fans in push/pull, Antec P182. Just took this shot a few minutes ago. About 65f ambient. Notice it has been up for 18 days. I got this processor from another member who was able to get to 4.0 with water.



Don't waste a lot of time with prime, but here is 2 hours from a previous shot.

Can you post your BIOS settings [Advanced menu only] please?

I tried to get something near 3.8Ghz daily but I can't belive that my CPU needs more than 1.36V for 3.8Ghz when it's RS with only 1.29V at 3.6Ghz...

It's a L740A843 [VID 1.2125V ]


Thanks

I can get 3.6 with 1.3v, but 3.8 takes 1.4v, so I'm betting that you need more vcore. I've had quite a few quads, and getting above 3.6 is not easy. They scale pretty good up to 3.6, but from there most need a lot of voltage and put out a ton of heat. Even if you are lucky enough to get above 3.6 with low voltage, it's still hard to keep the temps reasonable with air cooling. Once summer hits and my ambient goes up to 80-85f, I'll have to clock it down.

Here are my voltages:

Cpu Voltage = 1.4
Cpu Voltage Reference =Auto
Cpu Voltage Damper = Enabled
Cpu PLL Voltage = 1.5
Dram Voltage = 1.95
FSB Term Voltage = 1.3
N.B. Voltage = 1.4
N.B. Voltage Reference = Auto
S.B. Voltage Reference = Auto

Hey Lefy, how's that cpu coming along?

[Celcius]

Did a little more stability testing with my Q6600 (ram @ stock):

Hey Lefy, how's that cpu coming along?

it's awesome! thanks dude!

courtesy of forums like this, i found my 24/7 settings for 3.8GHz (422x9) and temps are below 60C under load. 1.4550 vcore in bios - drops ~.07 in windows. then droops a bit more under load.

What's your Vcore running at according to CPU-Z?

Everyone should consider downloading this nice tool from CPU-Z that monitors most everything in your system. It's especially good for those of us who use Vista 64bit, most applications do not give accurate readings for 64-bit sytems. Speedfan is one of the offenders with the exception to their beta.

My Vcore is set at 1.45v but during 3DMark06 and gaming registers from 1.42v and droops down to as low as 1.38v, usually 1.39v is as low as my system goes.

I'm curious what those that say they are operating at 3.6Ghz and 1.3v are really running at. Many motherboards overvolt their motherboards while others like mine undervolt. My MSI board on bios 1.1 overvolted while bios 1.6 at later releases after 1.1 undervolt (what bios settings says) the motherboard.

4x4 is making one of the most honest statement that I've read in some time. You need to use brute force or water cooling to get much above 3.6Ghz. I will go one step further and say that every "GO" stepped chip with good air cooling should reach 3.6Ghz or you've failed miserably. FrostyTech.com reviews all the good coolers.

If you look at all the water cooled systems with 3.8Ghz+ they usually have a Vcore of 1.55v-1.7v. They use brute force to break the 4Ghz barrier.

For the air coolers, (like me) we have to wait for the 45nm quads to break the 4Ghz barrier for a 24x7 stable computer.

I agree, that is pretty much the truth!

I have poor clocking Q6600 (1,325 VID), It´s Prime stable at 3600 with 1,43V, but takes 1,7V to be rock solid at 3800.

The chips that can handle 4GHz with low volts are very rare, but they exist.

But for most of the buyers, that can't try out dozens of chips, 3600 should be expected with good aircooling, anything beyond that is a welcome plus in performance and is a luck bonus.

What's your Vcore running at according to CPU-Z?

seems like my idle windows vcore is about 1.37v? and 1.32-ish under load? can't remember. i'll post a screenie after i get home from work, but my results are basically the same as zucker2k's here. i bought his chip. his board doesn't have near the drop and droop that mine does. oh, and my temps are about 5C higher I think. more later...

Q6600 G0

i wouldnt say they are "rare" so to speak... i would say about 8-10% of q6600's can do it

you just gotta test the processors before you settle down with one.
