1GB HD6950 with dual BIOS switch

post #1 of 10
Thread Starter 
Some of you may have hear about the Deal PowerColor struck to keep the reference PCBs so that their future HD6950s remain flashable.

Well, from that deal, the HD6950 2GB PCS++ was born as a 6950 that's guaranteed to unlock into a 6970 (save for the mem clocks).

The reason for the backstory is that I wondered if PowerColor would have the balls to give the same treatment to their 1GB HD6950 that they gave to their 2GB version.

From the following images it appears they have, indeed, equipped their 1GB version with a BIOS switch.

Here are 3 angles from the top of the card showing the switch.

Here is an image of the back of the PCB that clearly shows the positions for BIOS 1 and BIOS 2

I can't find ANY info on this card though. No reviews, no customer ratings, and PowerColor hasn't responded to my email at this time.

If this is a flashable dual BIOS card, it would be the only 1GB dual BIOS card available and at the awesome price of ~$240.

Does anyone have any other info on this?

Also, if I ****** up on something, go easy on me (first post).

I was holding off for the 7 series, but if this is the real deal then I think I'm going to have to splurge a bit.

but you should add your source to the Title, and a source link at the end of your post.

Yup.

Check out the links I posted at the top of the OP.

The first link explains a deal PowerColor worked out to continue using the reference PCB so that their 2GB cards (and now it looks like 1GB cards as well) can continue to be flashed.

The second link is a review of the PowerColor HD6950 2GB PCS++ videocard, which, PowerColor states, is guaranteed to unlock into a 6970. There is no 'maybe' when it comes to unlocking the PCS++, and, in fact, is pre unlocked by default. They are basically selling an HD6970 for the price of an HD6950 2GB.

Back to the 1GB model I've done more research.

Although PowerColor has not yet responded to my inquiry for official word on the status of this switch, I have looked at the PCBs of Rival AIB's cards.

For instance, go to Newegg and look at the back of the new Asus Direct CUII HD6950 1GB.

If you zoom in and look at the back of the PCB you'll notice that there is no BIOS switch soldered onto the PCB. The same follows for all other 1GB cards except the PowerColor 1GB.

It's very intriguging.

I've been emailing review sites about this too but haven't received any responses yet. frown.gif

But I am looking for a default Powercolor 1GB 6950 Dual-Bios Switch from newegg's "factory default" bios, and/or the unlocked bios if anyone still has these around. Or if you could drop a bios from GPU-Z, id very much appreciate it, I chunked two cards and I had to put a sapphire bios on them which, if you try to overclock or overvolt at all crashes instantly. Thanks in advance, I very much appreciate it, thumb.gif
