OC a Intel Q6600

[Lian]

Hi,

I currently have my Q6600 overclocked to 2880MHz. I have tried overclocking it to over 3GHz but when i restart, my PC doesn't boot, ea no POST screen and just completely blank. Have to reset the mobo via the jumpers to get it working again. My mobo is a very cheap thing i picked up in a local store, nothing special.

Currently my CPU FSB is set to 320. If i try 333MHz FSB my PC wont boot and that's about all i can change, with the exception of my memory timings.

PC:
MSI G31M3-F V2
Intel Q6600 with a Gigabyte G-Power2 CPU cooler
Nvidia 250GTS DK 1G
550Wat Gigabyte PSU
2x 2GB DDR2 800MHz Dual Channel
2x 500GB Seagate Sata HDD's

Temps are running well within acceptable limits. 30 on idle and 65 on load.

Is there anything ells i can do? Other than buy a new mobo? I'm guessing there isn't but just hoping.

If your only options are to change the FSB and timings then you may be stuck. :/

Loosen up your RAM timings to make sure that isn't what is holding back your OC.

Sounds like the Q6600 needs more juice, and without voltage options you're SoL to my knowledge. I have a Q6600 in my brother's PC on a mobo with settings like yours and the highest I can get is about 3ghz.

yea that's pretty much what i thought. Without the voltage option I'm very much limited on OC'ing.

I just installed Dual Core Center that MSI supplies with the board, but i hate programs like that running in the background. Managed 3.1GHz on it but gave up. I don't feel like changing the FSB through software every bluddy time i boot into Windows...

Anyways no biggy. Thanks though for the reply.

Anyways i finely got my CPU at 3.0GHz with a FSB of 1333. Ran prime (small FFT's) and "BAM" blue screen.......... So i was thinking (hoping) it might be my ram timings holding me back. currently its set to 6-5-5-15. Should i set it to 6-6-6-18 or something?

[edit] - I set the timings to 6-6-6-18 and running Prime as we speak. No blue screen yet!

not stable... going lower

you need to set Vcore to 1.40~ if you want 3.00 GHz STABLE
1.45 = 3.20 GHz = 355 FSBC
1.51 = 3.60 GHz = 400 FSBC

Best Setting is
FSBC : DRAM 1:1


1.40 Vcore and FSBC = 333
DRAM To 2.00D = 667 MHz
And set timing to 5.5.5.15 and test it ., you can even try 4.4.4.12

Cant change my voltages. Will have to buy a new mobo for that which I am actually currently looking at atm for crossfire as well. Good to know though for future reference when i do ONE DAY buy a better mobo. Thanks Kovaxo

LOL. I just posted a thread on this same processor. I am having problems boosting to 3 GHZ too. I have an MSI P7N SLI MOBO and tried the voltage with no luck. The highest I got was 2.6 GHZ. The funny thing is keeping the ratios 1:1 does not help me. I am running FSB 295 and RAM 791. Before I tried VCORE 1.4 and 1333 rated FSB. Could it be my RAM timings?

Thanks for the vcore. Worked great. Got my CPU up to 3.4Ghz although im sticking to 3Ghz just for save keeping.
