Bad flash on HD6450

[renq]

Hi!

I tried to get higher OC potential (more than stock max of 725/900) from my Club3D HD6450 1GB and flashed a Sapphire HD6450 BIOS found on the TPU database onto it. Now it doesn't start. First reboot into win 8 it got to login screen, and then went black. Have been trying to update the original BIOS file back, but it doesn't flash it. Tried "unlockrom" and "-f -p" commands, however whichever command (rather flag) I type into cmd, the flashing progress window appears and disappears quickly without actually flashing the BIOS. It happens with every flag: also with "atiwinflash -h"
The original BIOS was 128K, all the other BIOSes are 64K
Any ideas? The -h command worked on a Win 7 PC, should I try to update the BIOS on Win 7?
What other options there are?

TIA

You may have bricked that card if you flashed with a different rom size as the original. The only thing I can think of if you have tried to force it in DOS is to do the shorting of the pins and try to reflash.

Best practice in this situation would have been just to modify your own original bioses clocks instead of a different manufacturer.

try with the dos flasher

try with the dos flasher

Thanks for the quick reply.

What do you mean by "try it in DOS"? How do i do that?

 

[W1zzard]

make a bootable usb stick, grab the atiflash for dos from our download section, put your bios on it, boot from the usb stick, flash

google knows more

What pins to short?


I tried flashing it in DOS, went without a hitch, but now when I start Windows I get a BSOD w/ error system_service_exception. Intel HD Graphics is enabled and in use.

I dont understand why people still flash video cards... If you cant get a stable oc by overclocking the way everyone else does what makes you think changing the bios of a card to another completely different cards will end well. The only reason to flash bios is if its an updated bios for that specific thing.
