    Well, here it is everyone. After about 2 weeks of searching the web i finally found the settings i was looking for. So those of you out there with the Abit KR7A-133 mobo, here are the optimized bios settings for you. (Most of these settings are for optimizing your RAM)

    Core voltage- 1.65-1.75v
    W/ PC2100 set DRAM clock to 133mhz
    CAS latency- 2
    Bank interleave- 4
    Precharge to active (Trp)- 2T
    Precharge to active (Trans) 5T
    CMD ( Trcd) 2T
    DRAM queue depth- level 4 (I beleive this is the default setting)
    Command Drive Strength- Lo
    DRAM command rate- 1T
    Chipset driving control- Auto
    AAGP apeture size- 32- 64m
    AGP Fast Write- enable (if your video card supports this)
    This setting may cause instablity problems, but I'm having no trouble at all running this enabled.
