Ok first post ....so I've just got a new VTX3D ATI Radeon HD 6950 2GB (With BIOS switch) and I've got it installed and running perfectly at stock levels.
As the card has a BIOS switch I thought I'd have a go at flashing the BIOS to unlock the shaders to the amount in a HD 6970. First let me say that I've literally spent all day (it's my day off) trawling the web and researching how to do this and I've tried everything I can find/think of to get it to work but it'd just not happening so please don't think I'm being lazy!!!
If anyone has any ideas why it's not working with my card I'd appreciate the help. Here's what I've tried so far....
Maybe I've just got a card that won't unlock and if that's the case it's not the end of the world, I'll live with it. Just want to make sure I'm not doing something wrong before I give up settle for a standard overclock.
Phenom II x4 955 3.2GHz (OC to 3.9GHz)
8GB DDR2 RAM Dual Channel 800MHz
ATI Radeon HD 6950 2GB
Corsair TX650W PSU
Antec 900 Case (5 fans)
7200 RPM 1TB Hard Drive
Windows 7 Ultimate 64-bit
Any PC Gods/Godesses out there?

- Using the ATIWinflash GUI I always get an error about IDs not matching no matter what ROM I use.
- Using ATIWinflash through the Command Prompt the flash always appears successful.
- When I use any HD 6970 ROM (VTX3D, Sapphire, ASUS etc.) when I restart the computer it will not POST (just fans and lights but no beep etc.). I have to flick the BIOS switch to the 2 position and reboot.
- When I use a modded HD 6950 ROM downloaded from the internet (just shaders unlocked) it seems to flash fine, boots ok, but when I check GPU-Z the shaders have not increased (still showing 1408 instead of 1536). Exactly the same thing happens when I use RME to create my own modded ROM from my stock ROM with the 'unlock shaders to 6970' box ticked.
