Hello guys,this week i bought the sapphire 6950 non reference 2gb WITHOUT a bios switch,so i am wondering if i can unlock shaders,i tried many times but i can't even flash any bios,i tried on 2 motherboards,this i have is ASUS M4A785TD-V evo,the other one was ASUS M2N-SLI deluxe,on RBE when i try to flash a bios it gives an unknown error about bios or adapter,with atiwinflash when i try to flash the current bios it says it's already flashed and when i try to flash another bios it says "cannot erase rom".So what can i do?i have searched about EVERYTHING,i also found a bios for my current graphics card but how could i flash it,please help!it's the 11188-00-40R model and here is how my card looks like:

First off here a little something about the unlock
There are two types of 6950 unlocks:

Type 1 unlock: Shader increase to 1536 units (same as the 6970)
Type 2 unlock: Complete BIOS flash to a 6970

The type 1 unlock is almost risk free and can be achieved with almost all the 6950´s.
The type 2 unlock on the other hand is a bit more risky because due to the full 6970 BIOS flash also the timings of the 6970 and other settings which are different will be applied.
To some cards that ultimately can lead to card failure or mailfunction.
Further marginal differences can be seen here:

But be advised that the Type 2 unlock only yields about 1-3% performance increase.
Wheter the Type 1 unlock + stock 6970 clocks have shown to yield the exact same amount of performance a normal 6970 would achieve
So according to those results one could imply that a Type 1 unlock + stock 6970 settings would upgrade a 6950 to a full 6970 performancewise even though other settings or structural differences are unequal.



Both types of unlocks will void your warranty if something goes wrong so be sure to bare that in mind when doing it.
There have not been any long term studies about the affect of the unlocking process and further causations yet.....but I am confident to say that nobody has encountered any problems yet
So I personally would advise you to leave the unlock be as it is not included in the warranty and just overclock your card 5-10% higher ...thus a higher overclock should be able to not only compensate but even exceed the performance boost the unlock provides
And if you must have an unlocked card at least wait until we know more about its long term affects

I would also like to refer you to my thread in which similar questions and all advantages/features benchmark results,performance comparisons to other cards including all designs etc etc should be displayed and answered

http://www.overclock.net/nvidia/9848...md-6950-a.html

Here the full guide + tips on unlock from TechPowerUp:http://www.techpowerup.com/articles/...ng/vidcard/159
----------------------------------------------------------------------------
Now you should be pretty much informed about the unlock.
Here a little bit about the unlockability of the 6950´s out there:


If a card unlocks or not is depending on wheter or not it has been laser cut to make it impossilbe for software to unlock the unfunctional units.

Another crutial part of the unlock is for the card to have a BIOS switch so in case somthing goes wrong you can always flash to the second BIOS.

Basically 90% of the tested Twin Frozr III cards unlocked fine there are already some newer laser cut products around so be careful to check the arrival date of the card at your local retailer before buying it to ensure it couldn´t have been laser cut yet.


Hope I could help
Anything earlier than March 15th should be fine I believe

There is a high possibilty this card has been laser cut and therefor made impossible to unlock or flash.

When did you buy the card?
What was the arrival date at the retailer?

Even though it probably will not unloch and does not have a BIOS switch you can still overclock it to 1 GHZ which will provide you with higher performance than both unlock and flash together

Don´t worry unlock is highly overrated!
Most people don´t know that it results in only marginal performance gains.
Also don´t void your warranty it is far better to just overclock trust me

Because like I told you anything later than the 15th of March could have already been laser cut.

You card is probably laser cut that is why the flash and unlock do not work.
Also this model does not have a BIOS switch so it would also be highly unsave.

Stop messing with the BIOS this card will not flash just give it a healthy overlock

If you can't flash the card with the guides flating around (like the one in my sig) then your card isn't able to be flashed. The fact that you have no BIOS switch is a dead giveaway that it is not a referrence GPU, ergo your less likely to be able to unlock it. Just like the GTX 465's in the last fermi series from NVidia if you didn't get it early you missed out. Either go in for a card that has an earlier manufacture date or enjoy the 6950 as is.
