The stock BIOS is fine. What was happening supposedly was that GPU-Z and RBE were truncating the BIOS to 61kb files or so rather than the full 128kb which caused cards to die. Dave Baumann notified W1z about it and they found a fix with the help of some XS members and the correct BIOS is now on the site if your card died after a flash. A lot of members have revived their cards already..
