Exclamation sapphire 4850 dual bios

Right i thought i make a post for anyone that was having a problems with OCing or pencil modding there sapphire 4850, recently i came across a bios that gave me 785 on the core (with pencil mod) but after copying over it like a dumbass i wasn't able to get my 785mhz clock, but after searching for a week lol, iv came across a nice 4850 bios and thought id share it with everyone to see if it can improve there OC like it did for me.

I would just like to say im not responsible if your card explodes, please proceed at your own risk.

Iv currently got my sapphire 4850 running at 800mhz core/ 990mhz mem (seems more stable at 990 over 1000) with a pencil mod giving me about 1.3 on the Vgpu. Here is a link to the 4850 pencil mod.

The bios enabled me to get around 720mhz without the pencil mod feel free to help yourself :P happy modding :P

I used the Asus Top BIOS..with hash1 method for using 4870 clock limits on the 4850 BIOS. Worked great! Gave me stock boot clocks at 800/1100 and opened up the OC range in CCC to 900+ on the core and up to 1200mhz on the mem
