I will not try to engage the full 6970 unlock because the 1-3% are ridiculous considering that my card might be damaged.

So if you confirm that the Shader unlock will work with any 6950 regardless of reference or non reference my options increase dramatically.

Because I want to overclock the hell out of the card I want it to have good cooling..another reason why reference design won´t be any good in my case.

Here my first retailer: http://geizhals.at/eu/?cat=gra16_512&asuch=6950&sort=p (scroll down)

Here the second: http://www.ditech.at/search.do?searc...n=herstellerNR

What do you think ? do I have a good selection here? Which one of the cards in the links would you pick to have max oc , good cooling and shader unlock?
No, that's not what I'm saying. What I am saying however, is that the Power Color PCS++ comes with the 6970 BIOS. So you are pretty much guaranteed a card which will unlock and have a better cooler than the reference models.

Then we also have the 6950 Twin Frozr III which judging by recent experiences, is unlockable. It also has a BIOS switch and hands down the best cooler. On the other hand, I can't guarantee an unlock on this card, as it's not enough info out yet. Looking promising though.

Your other option is bying the cheapest 6950 2GB reference and smack on an aftermarket cooler.

You have all cards mentioned available.

The Twin Frozr III is said not to be unlockable.
Or at least running faulty and causing instability.

You said the best overclocker would be the one from MSI ...I forgot to mention that I would also like a voltage controller....does the MSI one have on? I couldn´t find out.

The Asus 6950 2GB has the same cooler as the Twin Frozr and a voltage controller too.
Also the Asus Cards are said to overclock best.

Then there are the Powercolor with also a dual fan cooler .....do those have a voltage controller?
and how does their overclocking compete to the Asus one?

I think I will be getting the ASUS ones because of Voltage Controller,claimed best overclocking ability and non reference design extreme cooling solution.

Only question is does it unlock cause it is non ref.

Those are the best non-reference cards of the 6950 series

http://geizhals.at/eu/a618757.html


http://geizhals.at/eu/a613014.html



1.)best overclocker

2.)voltage controller

3.)best cooling performance

4.)Shader unlock capability

5.)need them to fit my 2x16 PCI on my GA EX58 UD5

6.)if possible with the best features (Adapters,longest warranty,CF bridge!).


Which one?

Side Note:The Twin Frozr II has proven to be unable of the Shader unlock ...I am still not sure about the Twin Frozr III)

1.) Where are you getting this info? The Twin Frozr II does not unlock, my friend has one. Neither does t he DirectCU. Unless you can provide me with a link. The Twin Frozr III comes with a BIOS switch, so I'm fairly certain it can unlock. Best OCer is the Twin Frozr/DirectCU.

2.) Use Google, I'm not a lexicon.

3.) Twin Frozr III, ruling out DirectCU since this is a 3 slot card.

4.) Guaranteed? Power Color PCs++

5.) Everything will fit except the DirectCU

6.) I have no overview over warranties whatsoever, this information is still easy to find by yourself.

So according to you the Asus 6950 non ref that I posted a picture of above is not unlockable.

Ok then the decision has to made between the Power Color PCs++ and the Twin Frozr III ...what do you say?

Both have the same cooling performance,the MSI has a voltage controller I am not sure about the PC though, both will fit my 16 slots, both overclock great,both will be shader unlockable and both feature similar warranty ...so what should I do?

Ok I found the source which reinforces my fear that the MSI 6950 Twin Frozr III will not be able to be unlocked.

I will Quote the most important ones:

1.)THIS CARD WON'T UNLOCK PERIOD!!! This is a non-reference card so sorry but you are COMPLETELY out of luck. This card uses a custom MSI PCB which improves overclocking but disables unlocking the GPU. There is only 1 BIOS, not 2. Sorry for the bad news, but this wasn't a secret that this card couldn't be unlocked so don't go blaming MSI. It will overclock though far so try to get it to 1ghz to make up for the lack of unlocking. The cooler is also much better.

2.)you guys don't understand that a REFERENCE 2gb model is the ONLY 6950 that will unlock. No other will if it's 1gb or a non-reference card. It must look like this with 2gb of VRAM. Otherwise it won't unlock period.

3.)his is incorrect information so please refer to my previous post. It all depends on if the GPU has been laser cut or not; results are mixed for non-reference and 1GB PCBs.


So basically only the reference cards ensure the unlock..with the non ref cards it´s a gamble wheter or not the GPU was laser cut to disable it from being unlocked by software.

So there you have it! even though the Twin Frozr III has 2 BIOS´s it still does not ensure the guarantee that it can be unlocked.

This is really bad news ....I need a non ref card with a good cooler because I am not planning on slapping waterblocks on those cards-.-...what am I gonna do now?
Buying a ref and an additional aftermarket cooler won´t work either because they are all too big,too expensive or just not efficient enough-.-!

Any ideas?

I know the shader unlock basically only provides a marginal performance boost but still I want to get the maximum out of the card with good cooling.

Asus non ref can´t be unlocked, MSI non ref cannot be unlocked , that only leaves the PSC++ right?

Depends on case/airflow and the room between the two cards.

However, I am running a reference 6950 and I've never seen it above 65C at 40% fan speed while gaming all day. Then again, my case is extremely good for GPUs imo. 4x fans blowing straight at it.

I think the Twin Frozr cards will be fine if you have a fan blowing inbetween them,but can't guarantee it.

Don't think you read the entire review, because they overclocked it to over 1GHz which is more than 14% and could be pushed further. You also don't take into consideration that the card is already factory overclocked. It also doesn't have shaders unlocked.

It's unbelievable how much over analyzing OP is doing in this situation. The thread should have ended 4 pages ago.

The 6950 CF setup is clearly the best choice, period.
