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.
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.
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:
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.
