    I have a BFG GTX275 OC card:
    http://www.bfgtech.com/bfgrgtx275896oce.aspx

    My initial card (bought about 5 months ago) had the following BIOS version:
    62.00.5B.00.04

    For some reason, I started to have some problems with the card, and the replacement card has this BIOS version:
    62.00.60.00.05

    MVKTech has both of them up, but there are no release notes:

    Anyone know the updates/difference? :bang:

    I opened both of them with NiBiTor and found that the 62.00.60.00.05 - rev. 02 has a slightly lower voltage setting under "Voltages" => "Exact Mode" => "Extra": 1.17V (compared to the 1.18V in the 62.00.5B.00.04 - rev. 01):

    Besides that, everything else was exactly the same.

    while a lower voltage might decrease peak overclocks, it also decreases temps slightly, and decreases the amount of transistor leakage.

    Thank you both for the input. I did not realize that NiBiTor can do such amazing tricks! Also, I agree -- I would rather have stability rather than crashes due to overheats.
