In this review they say it comes with an unlocked state, only shaders and core speed is raised.

The GPU review has the dual switch too.. I think OP may have read the wrong review or something. -.-

Have you not been reading everyone saying I got my PCS++ and it doesnt unlock the shaders? All of the reviews that were with test samples say its got the switch, and it unlocks. all the reviews since the cards release? switch.... to get it to 880mhz.... not to unlock shaders.

Read the very top of the article.

The PCS++ HD6950 allows unlocking of shaders allowing extra performance

This is really weird. I got a 6950 PCS++ and it came with shaders unlocked already.

I sent the card back because it was faulty (turned out it wasn't) and got a 6970 instead, just for the extra juice. Has been an awesome card. Happy with the purchase.

Guess Ill just test it when I get it, I was hoping someone had the card already and could confirm. Problem is I haven't seen 1 successful unlock so far since release of non test models.

Dont listen to what others say, maybe they got a sample where the bios didn't come flashed - it can happen. the best and surest way is to try yourself.

regardless of it all, at the same clocks shaders only give 5% performance, so its not worth it, but i'd buy the PCS++ over the regular, or PCS one because it comes with a 6pin and 8pin power connector and thats helpful when you are gonna unlock or overclock.

I've been thinking of picking up the PCS++ myself but I may just not buy another 6950.

I was going to get the PCS++ regardless but I found GTX 570 for $30 more.

Beyond the fact that the Powercolor site still shows the press release stating that it fully unlocks the shaders, there actually are several reviews that explicitly demonstrate it. Including one iirc that actually shows performance metrics between both shader numbers.

Please someone with this card test this. He was very curtain these are guaranteed to unlock shaders, but will not 'flash'
This is awesome if true!!! Can anyone else test this? Mine won't arrive until tomorrow or the next day.

Coincidentally I'm going to try to find that review I referenced above. Now that I think about it, I think they may have actually stated that switching the BIOS, by itself, only raised the clock speed. They then reinstalled the drivers for the shaders to unlock. The reason it strikes a bell with me is because when talking about the performance metrics, I actually recall them stating that simply going to 880MHz did little in terms of performance increases ... but the shader unlock yielded around 9% or so. Why would they have a 880Mhz metric with the traditional shader count unless it does occur as you describe?
