    Hd 4850 "standard card" custom bios 700/1100 CCC 9.2 compatible

    Hi guys,

    was playing around with my old visiontek hd 4850's and as you know they had a pretty crappy bios that let the card idle up to 69c. Definitely needed a better bios and had one but ever since the newer CCC 8.12 and up the high voltage custom bios' didn't work. Actually anything above 1.158v won't work.

    Additionally with the stock cooler any fan speeds above 40% would get pretty loud which is undesirable for idle and surfing.

    MSI created a bios with enhanced powerplay low clocks of 160/500 during non 2d/3d use (idle/surfing) to save a couple of watts and reduce heat as well.

    So I created a custom standard hd 4850 bios (not for gainward/palit/etc) that works fine for the regular run of the mill visiontek, msi, ati, etc. cards with the following perks based on the MSI hd 4850 bios:
    1) 700/1100 clocks (upper limit of stability with stock cooler and 1.158v limit)
    2) 160/500 clocks for idle
    3) 1.158v limit for CCC 8.12-9.2 compatibility
    4) fan profile to have card idle in the 50's quietly (less than 40%) and ramp up to the 70's under load.

    I tested this bios under a couple of loops of 3dmark06 and Vantage with my visiontek card and it seemed to work just fine.

    So for run of the mill hd 4850's with stock coolers, I present you a nice custom bios. Please feel free to try and comment. Flash at your own risk.

    Revised the bios: Set a lower stable voltage of 0.968 for 160/500 idle.
    Revised bios here:

    Anyone test it yet?
    Just wanted to see the stability and cooling profile for other users =).
    Post a reply if you've had.
    15 downloads so someone must have tried it =).

    thanks for the bios

    but i saw some flaw, when doing 3dmark06 particularly on the cpu bench stage im having artifacts. i believe the voltage was too low on the 2d settings so I changed it back to the default voltage. Works great aside from that.

    So you saw artifacts with the revised (2nd post) bios with 0.968v?
    I'll check it out.
    Was then the first bios (original post) ok?

    i used the bios from the second post. im not really sure if that was the problem but when i increased the the voltage to 1.046, the artifacts where gone. btw i'm using a msi reference card.

    one quick question, can we set the voltage up to 1.2v? i've read from some that the max voltage on these cards is 1.2v.

    Ok then the first bios (first post) should be good because it is 1.046v.

    The max since cat 8.9? is 1.158v.

    Used 4850's are so cheap now - the 4850 and this bios is definitely the budget way to go!!!
