Sapphire HD4850 Bios Modded, Core upper Limit to 850Mhz in CCC!

[leonarderman]

Please note: Don't try to use Pencil mod if you don't have a better cooler (Water cooling is best for use). Because pencil mod can give vcore 1,4V - it'll make your HD4850 card too hot. I tried with my Sapphire HD4850 Toxic + Zalman VF900, it's so hot that I can't Overclock GPU core more than 815MHz.

leonarderman, do you think you could mod my HIS bios? I have it linked in a post at the beginning of page 2.
Thanks.

Here's your HIS HD4850 Bios file: HIS HD4850 Bios Modded
Core Upper limit 800MHz

Can you mod my original bios and change only the upper limits please? DiamondHD4850.bin
