Looking for HD 4850 512Mb DDR3 Bios

[EfterlysT]

I have tried to modified some 4850 bioses but i cant get it to work with any ATI drivers. I just get blackscreen when booting into Windows.
I want to raise the overclock limit and raise the gpu voltage. I am going for hardmod soon but need a descent bios first.

I found this old thread but all the links are dead in it.

Anyone have some 4850 bios and want to share them ?

Thanks. But i have tried to modify alot of thoose bioses already. I guess i have to wait until i do the hardmods before i can juice it up a bit.

When i try to set higher gpu voltage in RBE i guess i change the checksum and thats why i fail to use it with catalyst. I have tried many different drivers with no luck.

edit: I have got one Asus bios to work that let my clock the gpu up to 800Mhz. I am now doing 800Mhz with just pencilmod so need more overclocking ability. Anyone know how to get clocks like this:

I dont care about voltages anymore because i am doing hardmod in the next coming days. I just need to be able to clock higher.
