Hello.
I would like to apply this update, as I clearly am eligible for it having an older stock FTW2 card with 320GB/s memory, but it seems I have a bios revision that is incompatible with the supplied files. If I apply either the "original" or "11Ghz" files, memory type in GPU-Z goes to "Unknown" and I can't clock memory above 405Mhz.
Luckily, I kept a backup of the primary bios on the cards dual bios function, which saved me from being basically ruined in gaming, but you probably want to fix this.
GPU-Z of my card and bios revision (this is the primary bios that came with the card):
