Bios Modded able to change Vcore max to 1.327V. Mod more Volt take no effect!

But I think the card HD4850 is easy stable at core 700Mhz with vcore df. With my Sapphire HD4850, I can overclock core to 750Mhz stable easily! Try again or mod Vcore by Pencil to get more result!
leonarderman, do you think you could mod my HIS bios? I have it linked in a post at the beginning of page 2.
Thanks.
