Overclocking Lock?

[Droogie]

Ok so I can overclock my Q6700 to 2.99Ghz with no problems, and without touching the voltage. But if I try put it to 3, my PC goes to the bios information page, and says WARNING: System has failed to boot please press to delete to enter setup. Could there be some kind of setting that won't allow the bus speed to reach 300. I have an ASUS P5N-D LGA 775 NVIDIA nForce 750i SLI mobo.

than means you have reached your ceiling.

3Ghz is your ceiling, without raising voltage (like mine is 2.64GHz)

I suggest if you want a stable setup, run at 2.9GHz or less

dont worry, there is no lock. Is just your ceiling

Yes, but even when I do change my voltage, It still won't boot up. I've tried chaning both the RAM voltage and the VCORE, but nothing.

changing the voltage doesnt mean you will make it stable. especially since its quad core...

anyways, have you stress tested with prime95 in 4 different instances? you need to run that and make sure its completely stable for 24hrs or more before you try to overclock anymore, and even then it might not be the processor thats holding you back. try running the memory on a divider. i had a few sticks of ram before that just wouldnt run a memory divider... that held me back so i got rid of them and pushed my overclock an extra 300mhz..

Probably at your memory limits for there timming and voltage, just try setting it back from 800 to 677 at first and see if you can get your FSB higher. If so its your memory limiting you at there current timming and voltage for being overclocked.

I thought it was that too, but its so weird I can OC to 2.99 perfectly stable (10 hours of 2 instances of orthos) yet 3.00 won't even boot. Just seems really weird to me.
