Hi Everyone i want to overclock my CPU but im kinda insecure of doing it without help.
this is my system

-Intel Core 2 Quad Q6600
-ARCTIC Freezer 7 Pro Rev.2 with 92mm PWM Fan (CPU fan)
-Asus P5N-D (motherboard)
-2x Kingston HyperX 2 GB 800MHz DDR2 KHX6400D2LL/2G
-2x G.SKILL 1GB 240-Pin DDR2 800 Model F2-6400CL5D-2GBNQ
-XFX Double D FX-787A-CDFC Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0 x16

Thermaltake M9 VI1000BWS Black SECC Steel ATX Mid Tower
Western Digital WD Blue WD3200AAKS 320GB 7200 RPM


Hope you can help, Thanks :)

Just up your FBS a little at a time and test. You should be able to get around 333(3.0 GHz) without any other changes. Always keep an eye on temps. I like to stay below 60 C. If you want to play with the voltage you can get even higher.

Good luck.

The most I could ever get out of a Q6600 with G0 stepping was 2.8Ghz. My limiting factor was the FSB. If you're on a G35/G45 (i think) chipset you'll be lucky to break 3.0Ghz.

Another issue is crashing with your FSB ratio being greater than 3/4 I believe.

Hey thanks for the replies, i managed to get 2.8 with the asus software in bios.
it has an option for manual or auto and overclock i think and i did it and got 2.8 very stable.

i want to push it more toward 3.4 but im scared since im not sure what values need to be changed. i saw something about changing some ram values that looked like 3-3-3-4-3 (not the actual numbers) and got scared and didnt do anything.

what do you guys think .

Lets say you hit a wall in the ram department and your ram timing is like 8-8-8-12. You can loosen the timing by increasing the last number by 3 and if that doesn't work increase the first 3 numbers by one. If you get stable again after that begin to lower the last number by 1 until it becomes unstable and then increase by 1 and you should be good.

Like I said though with most 775t boards you'll run into FSB issues when OCing a Q6600 past 2.8Ghz. IMO I'd be happy with a 2.8Ghz Q6600.

I know this thread is kind of old, but if you want to overclock a Q6600 with G0 stepping on an Asus P5N-D, do this:

Set:
PCIE Frequency = 130mhz
Linked --> Sync Mode --> 1600mhz (RAM should be 800mhz)
Vcore = After Vdrop I am running mine at 1.312v STABLE w/ 8x multi..
RAM @ 1.91V
HT Voltage = 1.20v
NB Voltage = 1.20v
SB Voltage = 1.50v
LTD Frequency = 7x -- For 8x you need to raise the HT and NB voltage to ?? I haven't tried it. Sorry.
Notice I said I set my multiplier to 8x instead of 9x... Vcore for 9x multiplier needs to be 1.34v (I keep mine lower due to core temps running mid 60's C w/ 9x multiplier under load with my heatsink/fan assembly)

Raising the PCIE frequency helps you get a higher overclock with minimal voltage. This motherboard's PCIE frequency maxes out at 131mhz, but just run it at 130mhz. I still have sound, LAN, all PCI and PCIE slots work perfectly. One more note: AIDA 64 reports core voltage for this chipset to be 1.25v. I can play all of my games at max/ultra settings and over 30fps. 1.20v on the HT and NB seems to work excellent. Temps are nice and low, and I have a nice overclock. 1.20v is no joke. Try it yourself.
