Visiontek 4850 BIOS mod

[Drakan290]

Anyone have a link known to work with the Visiontek 4850? I want to up the voltage without using a pencil, as I have really high headroom with an Accelero S2 rev 2/fans and i'm sitting at 700/1135 no problems.
The ones from overclock don't seem to have Catalyst recognized my video card and I have to re-flash to the original Bios...

Which fans are you using? I'm looking to get overclock on my 4850 as well.

I jerry rigged my own 60mm high CFM fans onto the accelero, cools it down crazily good. Load @ 45c
I can use the ATI tool to get it to 700/1165, but I need a volt mod to up it any higher...

I just had to pencil mine to get 1.25v to the core, they run great at 750/1150 now. I couldn't get them over 1.20v thru the bios, which wouldn't let me go over 685.

I've bumped my thread twice now. Nobody knows jack about bios mods it seems.
