Title: 6950 BIOS Switch doesn't work? Post by: CrimsonGT on January 06, 2014, 06:30:58 PM I have had my Sapphire 6950 1GB Card for a couple years now and have used it to mine off and on since BTC was already 2$/ea.
As I have recently come back to mining and am just playing with this card on Alt Coins, I decided to look at unlocking the shader count. After opening the PC and checking it, my card does indeed have a BIOS Switch so I got quite excited. I flipped it to the 1 Position (as shown on a diagram I found), booted the machine back up but still only have 1408 shaders in GPU-Z. Despite tons of searching, I cannot find anything reported with these cards where the switch actually did nothing. Is it possible GPU-Z is wrong or perhaps a card issue?
