Completely wrong!
Please you seem like a knowledgable guy , you need to stop the unlocking rumor.
Every 6950 has the exact same potential of being unlocked it only depends on the fact if it has been laser cut and nothing else!
If you post it a newbie will read it and repeat somewhere else ...and it will go on further.

So please let us stop the chain reaction!

Completely right!

If the OP wants more info about the unlock here a post of mine I use in such cases
------------------------------------------------------------------------------
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

I am not aware of 'laser cut' issues and I am not saying those can be unlocked - that may not be. Further, I am not stating it is a guaranteed unlock. Unless I see threads where one of these reference models (which are already hard to come by) indeed did not unlock, I will continue with my theory that they have more potential to unlock. And if you notice, I used the word 'perceived'. The reason here being that if you look at all the threads about unlocking in OCN, 9 times out of 10, you see folks running into issue with a non-reference cards. Now this could be just a cause of laser-cut and not being laser-cut. But in my opinion, it shows the fact that the chances of unlocking is higher on a reference design because of the fact it may not be laser cut. Also, I want to point out that by unlock, I always refer to shader unlock using your OWN BIOS There is nothing noobness about trying that. I have not seen a single evidence where such an endeavor will brick the card. I never have suggested using a different BIOS or a 6970 BIOS.

Don´t you understand that by saying that you are fueling this untrue rumor all over again.

And that unlockability isn´t just decided by the fact of being laser cut or not lol?

I will try it another way:

If you have 10 apples ....every apple has the probability of having a worm in it...but if the company that sells these apples uses means to make it physically impossible for a worm to enter either one of those 10 apples the probability of all apples containing a worm is the same.

Got it?

If a card has been laser cut it is made physically impossible to unlock it meaning all cards have the same probability of getting unlocked or not depending on the fact if they have been laser cut or not.
There is no other theory, explanation or alternative it just comes down to that.

And AMD has made clear statements about inhibiting their customers from unlocking or performing unintentional BIOS flashes.

The laser cutting was performed completely random , meaning that there wasn´t 10 ref cards that could be unlocked and 10 non ref cards that coudln´t ...but after this claims you can anticipate fewer unlock probability by every new badge.

Hope I could explain it

Thanks Kung Pow for that explanation.

I think the long term ramifications of unlocking will be a shortened card life. Same as an over clocked card it will have it's life shortened by some which will also vary from card to card. Depending on how much of an OC and time spent in OC state. We'll have to wait and see what the unlock effects are as time progresses.

Either way, whether just over clocking, unlocking, or unlocking with over clock, nothing is for free. That's life.

P.S. Hey Kung Pow, I have a suggestion. Copy and paste above explanation, start your own thread on "Update - Unlocking the 6950" and then provide the exact steps for both types of unlock. I know there's another one out there but this would be a more updated thread. I'm sure AMD and manufacturers are not liking it and it was only a matter of time before they did something. Think on the 6970 sales have suffered and the money they have lost thus far? LOL.

Yeah that is my last attempt

Public class Please Understand{

String a;
String b;
boolean unlock probability = true;
boolean laser cut = true;

public static void main()
{


If( a == laser cut && b == laser cut )

{
unlock probability=false;
a = "I am a ref 6950 and cannot be unlocked"
b= "I am a non ref 6950 and cannot be unlocked"

System.out.println(" "+a )
System.out.println(" "+b)

return false;
}
else
{
unlock probability=true;
a = "I am a ref 6950 and can be unlocked!"
b= "I am a non ref 6950 and can be unlocked!"

System.out.println(" "+a )
System.out.println(" "+b)

return true;
}
}
}

It has been a long time since java xD but maybe you get it through this example

There is another thing about the unlock I don´t like.

First the possible damage because we still lack long term studies which show the affect of 24/7 for a year.

People have to understand that the unlock is unlike a simple overclock something we cannot control , measure, test or monitor.
It is a procedure which revives shader units that have been intentionally made unfunctional.
The Cayman XT and Pro are not exactly the same chip.
6970 and 6950 have various differences and extremely slight structural and core unsimliarities which are in perfect harmony with the overall settings of both cards both of software and hardware nature.
If you forcefully unlock units like that and therefore disturbing this harmony of component settings could lead to improper operation or even possible damage.

The fact that you void your warranty is a given when performing the unlock but that is not the worst part.

And even if there is nothing to it and the unlock is completely save in terms of a long term perspective ....most cards get killed during the process of unlocking because of a failing BIOS flash.

And here is the kicker that most people don´t know.

Because the majority says just flash the BIOS back to normal before RMA´ing it or don´t do it at all they won´t find out.

Every 6950 has a BIOS Log file implemented which documents and monitors any BIOS activity.
And the manufacturer can evaluate this Log unit even if the card is bricked.
A friend of mine works at Power Color and told me that in confidence.
So if they check it and see the card has been flashed RMA is rejected immediately.

Unlocking is nothing bad ...but there is so much hype about it that most newbies to the scene don´t inform themselves enough and blame the forum after killing their cards

Just be aware and safe

Is this card workable? For unlocking and overclocking. Heat issues do not bother me I plan on WC these cards at sometime or the other..

Thank you guys for all of the help

Yes that one is unlockable. I will also say that Sapphire is a very good company. In fact one of the first unlockable cards that came out. However what I can't tell you as a fact if they are being laser cut now. I highly doubt it though.
