Have you undervolted any 7950 cards, or do you know any 7950 that can be undervolted? If so, please tell me the full name (or preferably the part number) of the card. I'd like to get one of those for mining purposes.

I'll use your input to build a list here. As far as I can find, no such list exists yet. The list will help everyone who's looking for the same thing as I do Smiley

It would be pointless listing the 7950s that can be undervolted for 2 reasons:

1) Pretty much only the original versions of most 7950s can be undervolted.  I have 4 MSI 7950s with the 8/6 connectors instead of the newer 6/6 pin.  The newer ones are locked. Same with Gigabyte and XFX and Sapphire.  I assume Diamond, Powercolor, and any other brand would be the same.  The part numbers are usually the same between older and newer ones.
2) The only decent place to find older ones would be eBay (or here) and by the time you get them in your hands difficulty will have gone up 50%.

The days of GPU mining are nearing an end.  If you have cards then mine away.  It makes no point buying new or even used cards for mining now unless you need them for gaming also.

Thank you for the info.

It is surprising to me that they're locking all new 7950 cards. I recently bought two 7870 XT (Tahiti LE) and they're both unlocked. But it's good to know.

Are new 7970, 7870 (Pitcairn) and 7850 are typically locked as well?

(I agree that the days of bitcoin GPU mining is ending. So I mine litecoin Smiley)

my Powercolor 7950 reference can undervolt, but not too much.
otherwise cards will crash.
now I am running all my cards at 1.063v mining LTC
