    Default Can't Overclock Anymore

    I installed a new video card (EVGA GTS450) on my Gigabyte GA-P35-DS3P Q6600 machine and I can no longer overclock. The BIOS says that I am OCed to 3.2Ghz but when I run CPU-Z it says my CPU is running at 2.13Ghz, well below the stock speed of 2.44Ghz.

    It doesn't matter what I change the multiplier or FSB to, it always resets to 2133Mhz in CPU-Z but when I go back into the BIOS it is still set the way that I set it. Either 9x333 or 8x401.

    I tried encoding an H264 file and running prime95 to see if it would run faster under load but it stayed at 2133Mhz (8x266.7Mhz).

    Would a video card affect my overclock and if so, what do I need to do to fix this?

    What has me baffled is that BIOS says that it is overclocked but not only is it's not overclocked, it's handcuffed below stock speed.

    Do you see a red warning box when you enter the BIOS MIT page?

    You may just need to clear the CMOS, and then start over again with optimized defaults.

    Also be sure you are using the latest BIOS in case there is any compatibility issues with that card and an older BIOS.

    If you update please use Qflash, and disable "keep DMI data" before you flash.

    I've been trying for the last few hours to update the BIOS but I keep getting an error that the update ID doesn't match. First I tried @BIOS (before I saw your reply) and it kept telling me there was an update but when it went to install, it was the same version that I already have (F6).

    F6 is the latest what are you trying to update to?

    Yeah, I was looking at the GA-P35-DS3P page instead of the GA-EP35-DS3P. Looks like I'm screwed then. I'll take the battery out tomorrow and see if that helps but resetting to default or optimum settings puts me at 9x100 at 900Mhz. Either the CPU or the board is shot I'm afraid.

    I cleared CMOS which returned the CPU to stock speed and then OC'ed to 3Ghz (9x333) which it now runs fine at but trying to OC to 3.2 (8x401) causes a hiccup on reboot and kicks it back down to 2133Mhz. I've run this CPU at 3.6 before (not real stable) and have run it at 3.2 the last year and a half and now I can't get it to run at 3.2.

    Strange thing, after having my CPU OC to 3.85GHz with fairly low voltages it became unstable at some point and I had to increase vcore. Further more, to resume from hibernation now I have to let it "rest" for a minute before booting (e.g. enter BIOS or boot menu) and then reboot, or I get corrupted file and then need to repair the file system.

    Could be just a matter of settings that need to be changed. Post full BIOS settings maybe we can be for a help.

    I changed the voltage from 1.379xxx to 1.38xxx and it booted correctly and CPU-Z shows it as 3.2Ghz so I guess it was the voltage. I kept switching from 2.0 to 2.5 on the System Memory Multiplier, not sure if that had any affect. It's at 2.0 right now.

    Even 1.38v seems a bit low considering it's a 45nm processor. Is LLC enabled?
    Memory is 1066 s SMM 2.66 should be good with a little more MCH maybe.

    Q6600 is 65nm, and for 3.2GHz, ~1.4 is plenty in most cases with G0 stepping examples. It's only when trying to push a chip like that to > 3.5GHz that big voltages might be needed (~1.5-1.55V).
