intel core 2 quad q6600 kentfield g0 overclock

[Wicca]

o over clock the 2.40ghz to 2.80ghz and the bus speed from 266mhz to 313mhz i did a stress test for an hour and the max temp was 61 for core 1 core 2 58 core 3 52 and core 4 52 so i w ant to know did i overclock successfully

 

[Wicca]

also i did not increase my voltage i tried to go to 3.0ghz but when i applyed it the computer froze so had to do a hard reboot so overclocking it to 2.8 ghz is this safe

 

[Terronium 12]

I believe this is in the wrong section.

And you only stressed it for an hour, that's no indication of anything at all. You should do it for at least 8-12 hours. The temps are a bit high for 2.8 though. What HSF and thermal compound are you using?

 

[Wicca]

the temp is normal for this cpu i checked

 

[Terronium 12]

I said it was high, I never said it wasn't normal.

Again, what HSF and thermal compound are you using?

 

[Wicca]

i read all that you can get at least 3.0ghz with this cpu but i am happy with this 2.80ghz

 

[Wicca]

stock HSF and thermal counpound antrix also overclocking it from 2.40 it only gained 1 degree

 

[Terronium 12]

No. You can get far more than 3 out of a G0 revision Q6600, the only restrictions are your immediate hardware and your knowledge on overclocking. Of course not every G0 can do more than say, 3.2, but I've yet to hear of any G0 not being able to push beyond 3.

Again, an hour-long stability test is not an indication of stability at all. Run it longer.

 

[Wicca]

so does that mean that 2.80ghz is safe used clockgen and buss speed 313


also my ram is 256mhz 3gb

 

[Terronium 12]

Okay, I should be more patient...

Once again, no, run it longer. 6-8, or 8-12 hours. If it fails it's not stable...also you're using Clockgen, I would never recommend overclocking from within Windows. The BIOS is where it's at but if that's too difficult to wade through then you should be fine with Clockgen.

 

[Wicca]

i need to know i have a 256mhz ram 1 gb each should i upgrade my ram would it help my cpu

 

[Terronium 12]

Having RAM with a higher frequency allows for higher FSB speeds, you can circumvent this (even if your case) by putting the RAM:FSB ratio on a divider. That way the speed of your RAM won't impact your overclock.

So, short answer is no. Long answer is yes.

 

[Wishmaster]

Terronium 12 is correct, and I too agree.

Everyone has different guidlenes as to what a stable result in Prime is. Personally, I say 10-12hrs.
Some will say 8hrs is enough, but I have seen Prime fail (meaning unstable) at the 9hr mark.
But I think all will agree, 1 hour is not at all long enough. Not even close. So keep testing, just let it run overnight.


With a FSB, how much you can OC will depend highly on not only your settings, but the RAM itself.
As Terronium 12 mentioned, higher RAM will allow for higher OCs. This is why many OCers want 1066 Mhz RAM. its gives more Headroom.


Also, you probably do not want to push it too high with a stock CPU cooler.
So long as you stay at 65C or under (fully loaded) you should be fine. A better CPU cooler will allow for higher clock speeds in that temp range.

 

[Wicca]

the only prob i have it on default now cause it would not go into hibernation with 2.80ghz but will a higher ram help with the 2.40 ghz processor

 

[Terronium 12]

I'm not sure what you're asking. RAM won't help hibernation as I'm almost certain that's hard drive-dependent.

No. You can get far more than 3 out of a G0 revision Q6600, the only restrictions are your immediate hardware and your knowledge on overclocking. Of course not every G0 can do more than say, 3.2, but I've yet to hear of any G0 not being able to push beyond 3.

This of course will depend on chip, RAM, and motherboard, and heatsink used. BTW your temps are normal for what you're running given the heatsink you have.

I have a B3 and mine has been clocked to 2.9 for over two years now with idle temps at 31, load temps at 63. This is on an Intel D975XBX2, 4gig of PC8500 (1066MHz) RAM, and a Zalman CNPS9500 AT CPU cooler.

I have the memory running as close to 1066 (968) as I can get while opting to to take an optimal balanced approach to both CPU speed and memory speed.

 

[Wicca]

i would overclock to 2.8 but i do not want to have to run a stress test for 8 hours incase i break my cpu

 

[Terronium 12]

You're not going to "break" anything. Worse case scenario is the system halts -- you restart the system and perhaps adjust the voltage(s) a bit. I'd suggest reading a tutorial before doing anything further if you think you're going to break something.

This of course will depend on chip, RAM, and motherboard, and heatsink used. BTW your temps are normal for what you're running given the heatsink you have.

I said that, you drunk.

 

[Wishmaster]

So long as you watch your tempratures, and they stay in the range as recommended, Prime will not break your CPU.
And in fact, even if the CPU does get too hot, it will throttle itself and shutdown to prevent damage. But this is a worse case scenario.

As mentioned earlier, Id shoot for keeping it at or below 65C under load.

If its unstable, you get an error, many times a rounding error, and the test stops on the core that failed.
This is just an indication it is not stable and is making mistakes, but will not harm the CPU.

 

[sygnus21]

I said that, you drunk.

I was just getting to the point

Back to the OP, as Wishmaster stated if you keep an eye on your temps all should be well. The key is finding a safe setting where you get the most out of your overclock without getting too hot. This is where trail and error comes in.

Good luck.
