    Before I start, here are the parts of my new rig:

    Biostar TZ77B Mobo
    3770k
    GTX 670
    2 Solid State Drives
    External CD Drive.

    Today, I tried overclocking my CPU. Bad idea. Went into the UEFI Bios and disabled the turbo setting, enabled fixed CPU Ratio, and set it to 40 (100 FSB * 40 = 4GHZ). CPU Fails to boot on reboot. Ok np. I reset the CMOS and try again. Boots this time, except windows BSODs on load. I try to force boot via CD Drive and the CD Drive refuses to load too. Take out CMOS BAttery, Reset jumper again, CD Drive still bad. Try new CD Drive, it works, windows installs, all is well, except whenever I turn my computer on now, I get CMOS Failure then it boots windows. Does anyone see this CMOS Failure message being a problem? Can anyone explain to me why I had to reformat my SSD because I set a bad clock ratio in the BIOS? Help me understand please.

    Disabling turbo isn't necessary, it's a feature that has very few drawbacks.

    Leave all BIOS settings at default and just adjust multiplier to 40 if that's what you want. The base offset voltages should be more than sufficient for that clock.. and should be up to 4.2 or so.. beyond that you will want to either A. increase the offset or B. add load line calibration

    When you reset the CMOS your BIOS will no longer be on RAID setting maybe when using 2 drives and then yeah it will fail to boot.. or it may be in wrong mode AHCI vs. IDE.. just a thought.. or the OC could have corrupted the install.

    What happened to the CD drive was it just broken/old or what?

    EDIT: Biostar also has a BIOS update from 4/19/12 also do you have it? If you decide to update make sure you clear CMOS before you do it.. don't flash with an OC on just in case..

    Nah thats the weird part. I bought it 2 days ago. Just a plain ol external CD/DVD Combo drive.

    Went out bought a new one and it worked.

    Also, I was not running windows on RAID. Only on one SSD.

    Is the CMOS Failing everytime I boot a problem?

    Try F5 (I think) load optimized defaults and save.. it sounds like your configuration is not right

    shouldn't CMOS failure after that

    k i'll do that. Any idea on the failure message I get every boot "CMOS Failure"?

    edit: just saw ur post. Ok i'm on it.

    If that doesn't work follow this procedure from your mobo manual to properly clear CMOS:

    1. Remove AC power line.
    2. Set the jumper to “Pin 2-3 close”.
    3. Wait for five seconds.
    4. Set the jumper to “Pin 1-2 close”.
    5. Power on the AC.
    6. Reset your desired password or clear the CMOS data.

    If that doesn't work update that BIOS to the latest from BIOSTAR

    Did that. Still CMOS Failure.
