6950 an Upgrade? - Page 2

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 of the 6950 including all designs etc etc should be displayed and answered

Seeing that you have already read the techpowerup review there shouldn´t be many questions left after reading this

Hope I could help

I thought shaders only gave roughly 3% increase. Full 6970 can give you more. But you can OC 6950 with shaders unlock to give you more anyway.

Both the full flash and unlock don´t deliver more than 8% performance.
There is just too much hype about the unlock that people forget it doesn´t really have that much of an impact on performance.

I personally won´t risk my warranty and possible long term damage for a 4-8% performance increase which could be easily compensated or even exceeded by simple overclocking.

Just oc your cards and be happy guys
Unlock isn´t really necessary.

6950 unlocking ftw

6970 is ~11% faster than 6950.

More like 4-6% but that is not even the point.

The full flash or unlock does not upgrade the 6950 to full 6970 performance.
The unlock will provide approximately 5-6% performance increase and the full 6970 flash with all applied 6970 settings + reinstated unfunctional units will provide 1-3% performance.

You still can´t measure this as in 2% flash + 5 % unlock = 8 % which makes it equal or even superior to the 6970^^
The 6970 not only posesses higher quality RAM and other marginal structural differences it also as a different core design as we all know

The unlock feature of the 6950 is a well known modification still I am not very fond of it because there are still no long term studies about it.
And voiding your warranty for 4% performancei increase and possible long term damage or an unproperly operating card is just not worth in in my oppinion.

Especially to newbies this is dangerous because they read about the unlock in the forums not being sufficiently educated about it and just accept it as part of the card without realizing that it might cause some damage later on or void their warranty.

So those who are new and still undecided wheter or not to do it please wait until we have some long term studies that prove the unlock to be either safe or dangerous.

And you can all be certain of one thing a healthy overclock will always be the most benefitial and stable method in terms of gaining more performance.
And I am more than certain that the gain of either the unlock or flash might as well both together can and will be fairly exceeded by a good and well thought out overclock

It´s the computer scene and I know that it is constantly evolving and developing which is why people are always looking for new ways to improve and upgrade.

But sometimes you just gotta be old school

Thanks again. I wasn't going to unlock or anything as I don't have the money to simply replace it if it goes wrong.

I placed an order for one of these. Always liked asus plus it was the cheapest 2Gb model around. Considering watercooling but that will be in the far future how does the stock heatsink deal with overclocking?

That is a great card!
Reference cooling should be fine with 975 Core and 20% more on the Memory
You will have a lot of fun with this card

Thanks. As I recall Asus has its own overclocking software or something similar doesn't it?
