    GTS450 BIOS Mods

    Any request for GTS450 BIOS modifications can be posted here.

    Changes that can be made: Voltage cap raised to 1.21v, Fan Speed, vGPU, and Clock Domain tweeks.


    EDIT: Ok so we have confirmation, the mods work and seem to be safe!

    I just flash the BIOS in my ECS GTS 450 and pass the 999Mhz wall, my final result was 1005Mhz. Not the best but atleast im in the 1k mhz club xD

    BIOS Works great.

    Thanks CrazyNutz

    Thank you CrazyNuts However, I`m having a problem with the files. When I try to open the zip, appears a message saying the file is corrupt or damaged. Winrar doesn`t work either. It says "unespected end of file" .
    I'll wait for your answer or advise. Thank you very much.

    Use a different browser to DL the file, for some reason IE corrupts any file DL'ed from xtremesystems. Try firefox, or chrome, etc..

    Here it is. Also the checksum on your bios was wrong, did you try to mod it with a hex editor yourself? anyhow it's corrected now.
