*Official Retail G0 Q6600 Overclocking Thread*

[Utnorris]

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:

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?

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!

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!

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,

You know that there's very little benefit running the memory and FSB async, except on memory benchmarks. It will only stress your memoies and NB, which means more heat.

Long story short, my dad got himself a new pc and didn't mind swapping the q6600 i "accidentally found" in it for my pos e4300 (3.2g @ 1.5v).

ram at auto
400x9 1.3v bios set, 1.261 real, 1.264 cpuz (testbed in sig)
hsf = zalman 9500






only had it for about a hour and it's looking good more tests will follow

LOL, dude beside showing off some super PI do a few hours prime :>
I can run super pi at 3600 with only 1.22V easy...

Not showing off , (time is crap anyway?) as i said i only had about one hour that day so PI had to cut it.

I haven't been able to test further because under the current heatsink (zalman 9500) temps skyrocket to 80C after about ten seconds of 2*orthos even at 1.26v lol..

I guess the zalman will meet the bin
