I have a 6870 twin frozr II i recently tried a couple of BIOS from HD6870 sapphire to XFX ones .. but was not able to flash mine to get more on Vcore

i get this Error SSID Mismatch
m using ATI Flash in my bootable pendrive FAT 32


Please recommend or provide a link for a suitable BIOS with 1.188 or 1.19 on Vcore for HD6870



Thanx in advance :)

flashing hd 6870
Are you flashing on DOS?
If so, you can put -f in the command line to force the flash.
The SSID mismatch, is a normal occurrence when flashing from different GPU makers.
But you have the chance of killing your card by flashing it

Flashing Sapphire HD6970 with ASUS6970 bios.
Well it turns out is was something simple I was missing. To do anything with the sapphire 6970 bios you must first unlock it apparently.
atiflash -unlockrom 0
then atiflash -p 0 -f bios.bin
-fs forces flash despite ssid difference. if -f isnt working
The flash was successful and even allowed me to use smartdoctor. Unfortunately even smartdoctor cannot adjust the voltage on a Sapphire 6970. Otherwise the Asus bios is so far completely compatible with a sapphire card.
You should be able to adjust voltages with the most recent Afterburner beta (2.1 beta 6 IIRC).
