Unlocked my 6950 Toxic, was stupidly easy and so far 100% stable. Result!
How did you do it? Please explain the process.
my two where easy just flicked the bios switch
in case its too much work to read the previous page the toxic comes with 2 bioses, 1 is the normal locked shader 6950 bios and the other is a pre-modified bios which has a chance of unlocking the extra shaders. you can easily switch between the 2 by the flick of a switch, the switch is hidden by the xfire connecter.

Currently have my 6950/70 clocked at 920/1375 stable but I want to go higher.. As soon as I enable voltage control in Afterburner I get artifacts?

But of a strange one..
I've got a MSI Frozr II 6950 and a Sapphire Dual Fan Edition 6950 running in crossfire.
I did the Bios 'mod' on the Frozr II and it worked perfectly, extra shaders unlocked. I then go to try it on the Sapphire and it doesn't say it fails but it doesn't work either?
When flashing the MSI it popped up with a window giving me some details and would I like to restart.. With the Sapphire the loading bar pops up, gets half way and then nothing happens. No error message or success message
The question is what do I do now. I don't really need the Sapphire to unlock but it would be rather nice especially as it worked on the MSI card. Do I try my luck, sell the Sapphire and then get another MSI and hope for the best?
The Sapphire nor the MSI have the Bios switch either?

I wouldn't worry so much about unlocking the second card as it only provides very minimal gain at best. The highest gain comes from overclocking those bad boys!

Did you do the flash with both cards in your system? only i had to remove the bottom card and flash one at a time when i first got them.. not your models!!
Soldato
Yes I did, both times I've flashed my cards I've done it with them both in the system, just used 0 or 1 for the card when flashing.
Solved my Sapphire problem
It appears that stupidly I flashed the Bios of the Sapphire card
when I was messing around with it before. Some how I had managed to mess it up and as such I forgot the switch was in position 1 and I couldn't re-flash the card ha. Thus I was left with a card that would artifact when the switch was in position 2 and wouldn't flash with the switch in position 1.Managed to find the original bios on the internet, download and modded that to unlock the extra shaders and bingo it works
