HD 6450 1GB BIOS needed, please help!

[wantons]

Does anyone have the BIOS for one of the following cards:

GIGABYTE HD 6450 1GB DDR3
MSI HD 6450 1GB DDR3
Sapphire HD 6450 1GB DDR3

otherwise VisionTek, PowerColor or HIS are also fine.

Thanks a lot in advance!

background:
I have a ASUS HD 6450 1GB card and it can be overclocked using CCC. I tried to mod new clock speed through RBE, then flashed the mod bios back to the card. It crashes during Windows start-up.

Also, when loading the original BIOS, RBE warns me "Unable to find overdrive setting..." I guess this card simply can't be overclocked via ASUS BIOS mod.

I'm not sure flashing BIOS from other brand but same type of card would work. So I'd like to give it a try.

No similar type of BIOS is available in the BIOS db of this site.

Hi W1zzard,

Thanks a lot. There are indeed quite a few in the collection now.

I downloaded MSI, GiGABYTE, and Diamond, they all locked out the overdrive just like ASUS. Sapphire has 64KB BIOS (ASUS has 128KB). So the things left are PowerColor, XFX and Dell.

I tried PowerColor, Mod using RBE then atiflash it. At first, atiflash error out. I used -f to flash it. It did flashed but then it brisked !!

Using my old card, I then recovered and flashed the ASUS bios back.

At this point, I run out of idea to overclock using BIOS.

Is there anyway to mod the BIOS so that it unlock the overdrive feature?

thanks again.
