I recently bought a Gigabyte GA-P31-S3G motherboard, that came with their F5 bios, an Intel q6600 processor (stepping:B, revision:G0), as well as OCZ platinum 4gb(2x2) DDR2 1066 of RAM. I had a nvidia 8600gt videocard.

My question is: I have heard all over the formus I have come across that this processor which is stock @ 2.4Ghz can easily run @ 3.0ghz on stock cooling, with very little effort in the bios.

I have had no luck at all. I have tried the Gigabyte program called "EasyTune6" with bad results (system hang).

I am kind of new to this so any specific information would greatly be appreciated. One of the reasons I brought this board and CPU was because of the ease of OC.....but I have yet to see it.

Please Help....thanks in advance for reading this!!

PS.....I am using Vista HP 32 bit.....is it unusual for it to be able to see all 4GB of RAM?....I was told and have seen that it should only read approx. 3.5gb.... not to complain at all I am thrilled that all 4 are seen by the OS.

I was trying to did solely in the Bios but after having no luck with that ....I "tried" Easytune6 but would much rather do it by the way of the Bios

If you are trying to use EasyTune6 to OC your computer then you are going about this all wrong. You should be changing the FSB to overclock your computer in the system bios. Increase the FSB by a little bit every time and then run a stress test program (prime95 or orthos) to test for system instability. I would HIGHLY recommend reading an overclocking guide before you start to overclock your system.

If EasyTune6 isn't a program you are trying to use to OC your system and is another program all together then please disregard the above ;)

Ok defenatally stick to OCing in the bios. If you can't reach 3.0GHz flat out then increase the FSB slowly, testing for stability everytime. Once your system becomes unstable, start increasing voltages, lowering timings etc. to achieve stability.

Note that every processor is different. Yours might not be able to make it to 3.0 GHz just cause some other peoples could.

I did try to up the FSB but didn't get very far....I think I got up to 2.7ghz before system hang......it pushed my ram from 1066 to 1333...not sure if that was good or bad

I had talked with Gigabyte tech support and they told me of people having very good sucess with the same PCU.....air to 3.2 Ghz stable, 4.0ghz+ on water

yea it sounds like the ram is going to be the limiting factor there, sense its only rated for 1066. Set the ram divider to 1:1 and then overclock the system. After you have the processor at the desired speed then you can go and play with timings and dividers on the ram.

As for a good overclocking guide i believe we have some in depth ones here on toms forums, just to to the overclocking section :D

1. In Advanced BIOS Features Temporarily set C1E and EIST to Disable. After you see the OC you can enable C1E again.
2. In MIT set the PCIe to 100.
3. In MIT set Performance Enhance to standard.
4. In MIT set CPU Host Frequency (Mhz) to 333.
5. in MIT set Memory Frequency (Mhz) to 2.4. This is a mild RAM under clock to 800, you can increase the speed later.
6. In MIT set DDR2 OverVoltage Control to +0.3 that will give you the 2.1V that that I believe is the RAM spec.
Leave all other settings on auto and boot.

Immediately after the successful boot check temps with Real Temp. You probably should get a good aftermarket heatsink to keep CPU temps down.

If you want to test load temps then use Prime95 Use small FFTs.

If your temps climb to 70C then shut down prime95 and get a better cooler.

Technically you should check idle and load temps before you OC to be sure that there are no HS mounting issues.

You say you have a 550W power supply, but you didn't give the model. What is it?

Zorg: You are awesome!! I will try this and get back to you to let you know how it went!!...I will also check the make of my power supply and post it.

err no offence kyeana but do u have any idea of what you're talking about?? his RAM is not running at 1333 MHz! that would be his QDR! QDR/2=RAM freq. therefore his RAM should have been running at 533MHz stock (if he set synchronously) and now a lowly 667! 667 MHz on RAM quoted at 1066 is easy! both of you need to read up alot about FSB/QDR/RAM freqs.

ok, FSB x 2 = RAM freq. (dual pumping) FSB x 4 = QDR (quad pumping)

Therefore, QDR/4=FSB.

At stock, FSB = 266, RAM= 533, QDR = 1066.

Now, to get the CPU speed, you multiply the FSB by the CPU's internal "multiplier", which is maximum of 9 on a Q6600 (233 x 9 = 2400 or 2.4GHz)

Now, my recommendation for overclocking is for him to drop his multiplier to 6 and 400FSB to start, which should still be stable, as its still only 2.4GHz. Then, slowly bring the FSB up, dropping the multiplier if necessary (because if he left FSB at 400MHz and just upped his multiplier, he would get jumps of 400MHz each time! :O

thats all i got atm.

LOL no, i seen you in a few other posts mate u no wat ur talking bout :)

still, you could have picked up on kyeana's mistakes seeing as how u saw and posted on this thread before me...

Power supply info:

Power supply = Sunbeam 580watt ATX
model # = PSU-BKS580-US
newegg item # = N82E16817709011
purchased it 10/17/06

Zorg: thanks again!!!

V3NOM: thanks for the tips!! they were very informative...Although I don't think it is up to Zorg to point out everybodys mistakes.....his info was great and that is truly what counts.

I wil post detailed results of my OC when complete.

Thank you all for your help!

It gets tiring, I didn't read the posts closely. I just saw that alfie414 didn't get the info he was looking for and posted.

By the way the Q6600 will OC to 3G very easily there is no reason to go up in steps. Also with a lower FSB on the initial OC you rule out the northbridge and RAM as possible causes of a crash.

After you get the stable OC then you can move the FSB to 400 with a CPU multi 8 @ 3.2G and either Keep the RAM at 800 1:1 or go to 1066. I think at those speeds I would stay at 800 to reduce the RAM and northbridge temps, because the jump to 1066 will yield little, if any, real world performance gain. It will show up in RAM benches, but it won't make much difference.

OOPS, I was looking at the wrong PSU yours has 12V @25A. It's still a junk PSU and I recommend changing it ASAP.

Here are some excellent prices on some excellent PSUs. Let me know if they are too much and I will look for cheaper options, but you will only save maybe $20-$25 and you will get a far worse PSU.

CORSAIR CMPSU-750TX 750W
Overkill, but a really good deal on an excellent PSU
$99.99 after $20.00 Mail-In Rebate

CORSAIR CMPSU-650TX 650W
Excellent PSU at an excellent price.
$79.99 after $30.00 Mail-In Rebate

PC Power & Cooling S61EPS 610W
My preference, I have a soft spot for the PC P&C line, but any of the three are top flight PSUs.
$89.99 after $20.00 Mail-In Rebate

If you want any of these PSUs, then act quickly, because Newegg sales go away rapidly.

I also had a hang about 2 hours into Prime95 after OC to 3.0ghz at 800.

Here are results of temps:

w/o OC idle: min=26,25,22,28C
w/o OC idle: max=33,33,32,35C
w/o OC load: min=26,25,22,28C
w/o OC load: max=54,52,51,54C

with OC idle: min=29,26,28,31C
with OC idle: max=37,37,40,40C
with OC load: min=29,26,28,31C
with OC load: max=52,53,53,54C

when I discovered the system was hung...(test checked at startup, 15min, 30min, 1hr, 2hr(found hung), 4hr(didn't make to 4hrs)...the bios CPU temp was 41C. I also then disabled smartfan to have fan at max at all times.

Results from Prime95 (version 25.6):

FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

I couldn't find the file stress.txt even with a system search.

Could the Power supply issues you mentioned be the reason for hang or should I reduce something in the Bios settings?

Thanks for all your help!
