*Official Retail G0 Q6600 Overclocking Thread*

[Utnorris]

I do my 3.6Ghz at 1.44v and the loads don't go over 55c and that is running a torture test. Most of the time it rarely exceeds 45c.

What kind of load temps do you get with that cooler?

[asap]

Hi, guys :-)

i'm a noob at OC, i bought my PC couple months ago, Q6600 FPO/BATCH # L731A481 Pack Date 09/28/2007, the system already watercooled.. i ran it stock until i try to overclock this q6600 to 3.2 (8x400) 1.25v, it worked, prime95 stable, but when i change it to 3.6 it needs 1.48v to get stable.. man! i thought it was like others that need around 1.35v to 1.42v to get stable at 3.6 or 3.8.. well, i move it back to 3.2 again :-) what i wanna ask... is it good enough to do tasks like video encoding, games and maybe moderate rendering with 3dsmax at this speed?



thanks guys,..
now i like overclocking

[Jor3lBR]

10 Hours+ Prime95 BLEND test stable.

I got my low VID chip to run at 3600Mhz (400*9) with only 1.28vcore (last cpu needed 1.38v for the same and would reboot with 4hours of Prime).

I use Asetek Waterchill kit + Apogee GT block temps and volts as follow (Hot Day, Radiators Fan on Silent Mode 7v, Case Fans are off, Case is Closed and Adjust CPU Temp: +9):

Normal Load Temps with case fans on, radiator fan's 12v and mild day temp: 39-45oC.

[Gunlance]

Man I hate my quads .
L724A760 - VID 1.2875 needs 1.575v in bios to get 3.6 GHZ Prime stable 24 hours.
L740B307 - VID 1.3125 needs 1.525v in bios to get 3.6 stable for 24 hours.
Maximus vdroops like crazy with no voltage damper enabled.

[Shocky]

What cooler are you using? Throw some water on it and the temp should go down. Is it a B3 or a G0. B3's run very hot and don't OC as well. If it's a G0 you probably got unlucky and got a bad one.

120 Ultra Extreme with 2x120mm 1600rpm, I’m not using water, it's too much expense and hassle, yes it's a G0, yes it's probably bad one which is why I hate you guys as I NEVER get good overclockers.

[PossumK]

L739A466: VID 1.30, needs 1.47-1.48V (after vdroop under load) for 3.6 GHz - average core temp around 65C with Prime95 small FFT test

L744A469: VID 1.325, needs 1.50V (after vdroop under load) for 3.6 GHz - average core temp about 62C-63C with Prime95 small FFT test

Which of these should I keep? The one that needs 0.02-0.03V less vcore or the one that runs 2-3C cooler?

[~aoe~]

Just based on the information you provided, I'd personally keep the one that requires less vCore. The difference in temp between the two is minimal.

You could try to see if either processor is capable of running at 8x450. If so, then you should require less vCore and notice lower temps. However, this may only be useful to you if your memory is also capable of running at 900MHz.

So let me make sure I understand correctly, you get 3.6Ghz on 1.28volts, you are using water cooling and with that low voltage you still hit 56c under load? How warm is your ambient temps?

Q6600

VID 1.3

1.4925 in bios to reach 3.6 stable (9x400)

load under orthos max on any core is 52C

Recently lapped my TRUE which helped

[EagleRock]

Guess i had really bad luck my Q6600 go VID 1.3 need 1.38v to run 3.2 stable (8x400)
37c idle and 56c load

bad bad

It really depends on room temps, that was a hot day and case is closed and radiator fans at 7v. I also suspect that my Apogee GT isn't making good contact with the Q6600.

Normal load temps for me fluctuate between 39oC-44oC max if I use 12v on radiator fan's and turn on chassis fan's... And keep in mind I have PC Health Status: Adjust CPU Temp: +9 set on the BIOS.

Here is my Load Temps today with 12v on Radiator Fan's (now running DDR2 at 1200Mhz):

I would just think that since you are able to do 3.6Ghz at such a low voltage your temps would be much lower than mine. I am at 1.44v and my loads are at 55c, that is with ambient around 23c. I am cooling both the cpu and video card so I kind of expect it to be there, although I am going to tweak it to see if I can't get better. i am just surprised at your temps with such a low voltage. I guess I was wrong in thinking that the lower voltage would translate into lower temps.

I know what you mean, but mine is running -12oC cooler then yours and I think it's a huge difference right there!

As I said I rather have a silent PC so I turn all fans off and leave Radiators at 7v.

I apologize, your first post shows your temps at 56c and that is why I was confused. I don't run my fans at 12v either, I suppose I could and that would lower the temps a little, but I prefer the near silent operation too.

Anyway, if your temps are around 43c then thats great. I am thinking I will have to do some sort of chiller to get mine down to that range, but we will see after I do some tweaking.

Good overclock, since you have such low temps you should try for 4Ghz if you haven't already.

No problem mate, temps are tricky and depend in a lot of factors!

I see you have a BOWED Apogee and mine is original. Every time I unmount the block I see poor contact between them. I think the past we are using is a factor too, I used to like MX-2 but I think I'm changing it.

You could try to unmount the block and see if you have a perfect contact also.

I got 4000Mhz with my old Q6600 (even 4050Mhz wPrime stable) but it was too hot and needed 1.50v to do so.

With this new one I'm moving slowly I will let it "burning-in" Prime95 for a week or so and baby step it up till I reach 4005Mhz (445*9).

Good luck with yours too!

[Prozzac]

I see that alot of people her is whining about how bad their CPUs are, but i would kill to ged a Q6600 that got up to 3.6 at 1.55 volts.
Mine isn' prime stable at 3.2 if I go under 1.55 volts!
My CPU is the sh1t!

Thought I'd share my results with everyone. I got this motherboard and cpu from newegg earlier in the week

DFI LP LT X38-T2R
Tuniq Tower

Highest I've been able to boot into windows is 3.8Gz, but system freezes and temps idle in the 60s. It also took 1.58v to get this.

I was able to run a tests at 3720Mhz (picture below), but the system isn't stable and load temps reach 75-77c. I believe the CPU Voltage was set around 1.42-1.46 for this test.

I'm currently running at 3600Mhz (1.37v) and all seems stable. Ran a load test last night and the system stayed up without problem. Load temps are hitting 69-73 (depending on core), but the system idles between 48-54 depending on the core. Anyone have any tips for me? I just recently upgraded from my trusty Athlon X2 4200 system I had for about 18months. This is my first Core based cpu system and I haven't mastered everything yet.

Also, Should I be worried about the 4-6 degree difference in the highest to lowest cpu temp readings?

[superbowtie]

feel pretty lucky now..

i'm been tinkering with mine for a few days now. and i'm now stable at 3.8Ghz with 1.44v. had it at 4.0Ghz but it needs like 1.48v to be stable. did get a super pi 1m run though at 12.7 seconds.

I still don't get how people say the tuniq tower lapped is not as good as the TRUE. If anything its within a few degrees. idle i'm in the low 40's high 30's with a 17c room temp. thats with the fan running at 8.0v. stacker 830 with 6 120mm fans all at 8.0v. crank up just the CPU fan and i'm at low/mid 50's in prime. If anything Its gotta be the case setup. btw thats with dual 3870's in mine. to each his own.

Yeah, I need to check the contact this week. I can get it to boot to windows at 4Ghz, but it crashes under any type of load, That's at 1.6v (which is actually 1.55v on my board) so that also runs the temps up. I would kill to be able to get 4Ghz at 1.5, that would be awesome. Don't get me wrong, I like the fact that I can run at 3.6Ghz with ease, just want to be able to go to the xtreme,

Utnorris

[Utnorris]

If your cores are showing a different temp on each one and its a pretty good spread (like 5c) then you may not be getting a solid contact between your heatsink and chip. You can try adjusting the mount by tightening the corners and see if that closes the gap or you could lap both the cpu and heatsink so that the fit flat against each other. Lapping usually will lower your temps 3-5c, but it does void the warranty.

Good luck,

Simalar temps to mine with an Ultra Extreme, same volts too, other then lapping the heatsink or CPU i'm not sure theres much else to do.
