    Default can't overclock e7300 - no reason :(

    Hi.

    I've been working on my rig happily for about 8 months.

    My config:
    e7300 2,67 @ 3,33 (not anymore :( )
    ep35-ds3 (2.1) bios f4
    4x1gb a-data 800mhz

    I was able to work with no issues slightly overclocket to 3330Mhz.
    Today with no reason i can not change fsb (cpu host frequency).
    I can change it in bios but in windows it is again stock 267 Mhz (in bios it is shown overclocked). Max fsb i can reach is about 270... I tried swapping ramms and nothing :(

    Any ideas??

    In windows where? Use CPU-Z and see what you get under load.

    cpu-z shows 2,67 mhz, at startup it's 2,67 too. In bios i've 3,33ghz and that does not comes back to default. Sorry for my english :)

    Don't worry about the english.
    First try to load optimized defaults in main BIOS screen, then reapply your changes. If that doesn't help, you may need to clear CMOS.
    On how to clear CMOS read the second part of this post

    It stopped working without reason and now it works again...
    I have no idea what is wrong. Maybe ramm are overheating??
    I have cooler master sileo 500 and it has now back holes. 2 pairs of ramm sticks are very close to each other.
    i have no other clues...

    ps Orthoss memory test fails after a couple of minutes

    Which Orthos test fail exactly?
    Fill the template in this post with your own settings and post ot back, people will probably be able to help you with stable settings.
    Also put your system specs in your signature with a link to your ram specs.
