    Question Failed CPU OC

    Hi guys, I have a E2180 running at 2GHz, installed on a Gigabyte GA-G33M-DS2R/S2.

    Whenever I try to OC it above 2.1GHz, it simply reboots to default settings. Any tips on how to stop this?

    Regards,
    Mungo0

    Re: Failed CPU OC

    what RAM are you using? What steps are you following to OC?

    Re: Failed CPU OC

    Well, I'm using OCZ PC2 6400 4-4-4, 2GB RAM.

    I'm increasing the CPU Host Frequency to 210, and the multipler is 10X

    Re: Failed CPU OC

    He's using OCZ pc2-6400 on auto timings (presumably 5-5-5-15), I've just advised him to set the right vdimm and see if it boots properly then.

    EDIT~ beat me to it

    Re: Failed CPU OC

    He says it still fails to boot when going beyod stock speeds. Any help would be appreciated, as I advised him on this build and its quite embarrasing when it fails to deliver!

    Yup. For reasons unknown, the computer reboots when reached 2.1GHz, then defaults to 2Ghz.

    Whenever I try anything higher than 2.3Ghz, I have to clear the CMOS Jumper, then reboot, which is a pain.

    Re: Failed CPU OC

    Have you tried setting a lower (much lower) ram frequencey?

    Set your ram to its lowest possible speed and 5-5-5-15 timings and then try to OC your CPU.

    Re: Failed CPU OC

    Bhavv, I tried that the first time, but it still rebooted. Krumm suggested that it might be Intel's Speedstep coming into effect.

    Re: Failed CPU OC

    Turn off speed step, make sure Vcore isn't too low, raise the CPU:RAM ratio and try booting directly at 266mhz.

    Okay, but where's the option to disable speedstep?

    EIST. (enhanced intel speedstep technology)

    Also disable C1E (another power saving feature).

    Just had another look, and can see nothing related to either option

    Re: Failed CPU OC

    perhaps in the advanced Bios settings, there's something like a CPU FEATURE option somewhere?

    Inside, there might be thing like EIST, or speedstep tech..

    Can't believe there's nothing in the BIOS..

    Well, I've had another look, and absolutely nothing appears that's related to CPU



    EDIT: Whoops, I saw it in the advanced BIOS options. disabled both settings, but whenever I set it to 2.1ghz. it just reboots and defaults to 2 Ghz
