looking for modded hd3850 agp bios

[DTV DRAGON]

hey guys iam wanting to know if anyone has a oc'ed modded bios for a sapphire hd3850 512 agp video card, I want something better than the 720/950 that CCC allows us to oc to. Ive tried rivatuner but doesnt seem to work properly for me even after oc'ing it with riva never seen any increased benchmark results so want to use a modded version of the bios to overclock that way please let me know what ya have or any other ideas for oc'ing these cards thanx Dragon

I am looking for the same thing.

Anyone worked out where the lock is yet? (I know where the CCC max values are in the BIOS, but if you change them the drivers don't load)
or
Is it possible to safely use a PCIe 3850 or 3870 DDR3 bios? I am tempted to try but I suppose I better make sure I have a PCI card onhand b4 I try in case it bricks.
