Howdy On April 18th I bought a VTX3d 6950 (twin fan) from a shop here in Australia. Serial number is PG1103006989. No matter what I try, I cant POST after flashing a 6970 bios. If I flash a modded (shaders unlocked) 6950 bios, GPU-Z always reports 1408 shaders. Have even taken a copy of my own bios, modded it with a script, and re-flashed it. POSTS fine, but no unlocked shaders.... Just loaded RBE (Radeon Bios Editor), and checked my current BIOS....and it reports shaders are set to the 6970 count. Another user on the forums, Planetmoo, has the same card from the same store, serial number is only 4 digits off. His ends in 6985 and mine ends in 6989.. He states in another thread here: Mine is PG1103006985 (dual fan) and it unlocked fine with Wizard's script, with 1536 shaders displaying in GPU-Z Planetmoo and I chatted and went through the steps. His unlocks, mine does not. He even emailed me his modded bios, which still wont unlock the shaders. Another user with identical cards states: VTX3D 6950 2GB - S/N PG1102025161 (9/4/11 arrived in stock that day) shader unlocking no problem VTX3D 6950 2GB - S/N PG1104011852 (19/4/11 arrived in stock that day) shader unlock removed. The only reason I can see why mine fails and Planetmoo's unlocks, is that somewhere between the 4 serial numbers between our 2 cards, VTX3d changed the design somehow and locked the shaders. Could I be this unlucky? The serial numbers seem to include the manufacture date year then month, followed by 6 digits. PG PG1103006989. Thoughts? Suggestions?
