    Exclamation CPU no longer Overclocks

    My CPU won't overclock any more. I've had it overclocked to 3ghz sometimes 3.4ghz for a couple of years now but it now no longer will do that. But the strange thing is, is that in the bios all the settings are set to as if it was overclocked. Like fsb is at 333mhz, multiplier at 9. and all my voltage settings are set to when it was overclocked. I cleared the cmos and tried again, setting all the appropriate bios settings, it booted as normal but when I get into windows it says my CPU is @ 1.8ghz, which is stock.

    Any ideas?

    Re: CPU no longer Overclocks

    Is EIST/Speed Step disabled in the BIOS?
    What does it say at on the BIOS splash screen? Windows itself often reports wrongly. Are you using CPUz or similar to report speeds?

    EIST is enabled. The splash screen doesn't list what my cpu speed is, or it comes and goes too quick for me to notice and I right clicked on my computer to see the CPU speed, I used cpu-z and rivatuner and they all say 1.8ghz. Also the performance in my games has dropped significantly.

    Re: CPU no longer Overclocks

    Disable EIST then it's clocking you back as you're not taxing the system.

    Re: CPU no longer Overclocks

    what does cpu-z report the multiplier as???

    It may be going down to 6 when the CPU is not working, due to as said by OiD, EIST (speadstep)

    Re: CPU no longer Overclocks

    It's not clocking back, it just simply isn't overclocking at all. cpu-z lists the multiplier as 9 @ 1.8ghz. I know its running at 1.8ghz also because I have a g15 keyboard and rivatuner tells me what clock speed my CPU is at on the LCD. And when playing games its still at 1.8ghz.

    Even when I try only overclocking it slightly, for example to 2ghz, it still says it's at 1.8ghz within windows.

    Re: CPU no longer Overclocks

    Although it sounds like some kind of BIOS problem have you tried reseating the hardware
    and reapplying the thermal compound, just to rule it out.

    You could also try reflashing the bios.

    Re: CPU no longer Overclocks

    I haven't tried reseating the cpu, but i think i will try that. Flashing the bios though I'm not sure i want to do. I have my windows system drive in a raid 0 configuration. If I flash the bios, will I lose that and have to reinstall windows?

    Re: CPU no longer Overclocks

    Ok I had the same problem with this board.
    With my board it let me change everything: vcore, memory settings and alter the multiplyer but no matter what I set the FSB to even up one increment or underclocked it still came up as being default (266.7 mhz) in cpu-z.

    Here is what I did to solve the problem:

    I powered the PC down completely and removed the power lead to the power supply I then removed the battery (on the motherboard) completely for 10-15 minutes and then replaced everything and then restarted the PC and loaded in my overclocked settings profile (set up an overclocked profile by pressing F11 or F12 when in bios) - when I restarted the FSB setting was taken as it was entered in the Bios. As I say it seems to be a very fussy motherboard so when powering up don't have anything else connected to the PC that you don't need (like external hard drives etc).
