q6600 OC help! - Page 2

post #11 of 33
Wait, are you saying you pushed it straight to 333??!?!?!? You're failing the POST and reverting back to your stock clocks. Try 270 first.

EDIT: What BIOS version are you using?

266 - 333 will just shutdown and reset your cmos probly, thats why it booting back up at 266.

also there is a whole slew of things that need to be disabled...
speed step
eist
cie

pci frq to 33
pcie freq to 100
mem multiplier to 2.0

there is more

if you are not aware of that yet, I will post the list when I get home.

but it wont OC stable without the right settings, its not just bumping the fsb from 266 - 333 and viola

not sure how much diff the bios options are on the P35 board compared to the P965 but here are my non default settings.

CIA2 - Disable
PCIE - 101
PCI Freq - 33
C1E - Disable
EIST -Disable
Virt Mem - Disable
No Exec Mem - Disable
ctrl+f1 unlocks hidden tweak
Set mem multiplier to 2.0
Set DRAM to Manual

Up FSB by intervals of 10, stress test and watch temps between each interval.

Leaving speedstep enabled will not cause instability. Once you start overclocking, you will have instability, this requires more voltage.
post #15 of 33
First disable SpeedStep and C1E to make sure that you're seeing your numbers properly.

I notice many people freakout about this and say that the multi is saying 6x in CPUz when in the BIOS it is set to be 10x for example...

Once you have reached your targets, you can enable EIST/C1E ... I leave mine on, to save power when idle (2.4GHz 6x multiplier idle, 3.6GHz x9 at full speed)...

it is now working... i started from 275 fsb, increased fsb by 3mhz increment til i reached 315. now i tried 317 and it failed to boot, what should i do? core voltage set to 1.37v? is it safe? i need your support guys, i dont have extensive know-how on intel OCing, my first time here

Increase your voltage by 0.005, boot, if it fails increase by 0.005 again. Keep adding voltage until you've added up to 1.42v, once you get there, it's not your CPU holding you back. You'll need to start overclocking your RAM. The Q6600 is good until 1.5v for long life. Watch your temps as well, you need to stay under 55C on load for long life.

guys here it is... ive been these far, ive reached 3.2ghz @ 1.375vcore and still in progress. heres my screenshot http://i278.photobucket.com/albums/k...dy66/newOC.jpg

it never fails even a single moment... i just stopped the orthos just to let u know the progress of your helpful inputs. 356x9 (3.2ghz!) ill push it to its best OC but ill stay at 3.2, im happy with this.

please evaluate my OC settings

Multiplier: 9x
Bus Speed: 356
Vcore: 1.375
Mem multiplier: 2.0
PCIE freq: 100
dram timimg: 5-5-5-15
post #19 of 33
Orthos has to run for quite a few hours to make sure you are stable...also may i suggest using Prime95 as it tests all four cores silmutaneously without the need to run two orthos instances.
For now you can check stability running a stress test for approximately 20 minutes and go up until your desired overclock. Once you reach it...stress test for at least 4-5 hours or even 8 hours if this is going to be your 24/7 overclock.

definitely a decent OC/voltage and your temps look good if that image is load temps.

But definitely run prime95, 4 instances, small ffts for at least 8 hours if your going to run that OC 24/7

Ive failed at 4,5, and 6 hours and found that just one more bump+ voltage will stabilize it.

Its just to be sure you dont have probs down the road a bit
