Sorry first post got lost in the ether, posting this for the crawlers:
Note the cards I have had "MONICA" in place of where the model number should be... on the bottom was the following part number : 7121A10000G On the back of the card was: 102C3861000 000001
OK! Well perhaps some of the mystery has been solved...
So according to the guy I bought these 7 cards off of, they were salvage from a dead games developer... So this led me to go back to my old AMD Developer account and poke around... The current working theory is these cards were early developer samples which were available to dev's to test aspects of the new architecture before the final PCB/chip design on the production cards were settled. IE they aren't internal engineering samples, but rather partner developer samples which were "my guess is" under an NDA (which may or may not have expired.) Regardless I suspect that ATI never meant for these cards to get into the wild and were probably supposed to be scrapped at end of life. So if you happen to have one of these cards either it "fell off the truck" OR maybe there was a bankrupcy auction or some such thing and some poor sap ended up buying a bunch of cards thinking they were "real."
never the less a few more points...
They show 768 shaders and ~38Gtexel/s out of the box..... I flashed 2 of my 7 with the 7950 Bios Boost update found here: http://www.rage3d.com/board/showthread.php?t=33993264
which increased my shaders to 1536 and boosts the fillrate to what it should be for the REAL pre update 7950 IE ~80Gtexel/s... however if your using these cards for Scrypt mining.... sorry to say I "think" your out of luck. Iv been screwing around with clocks and voltages all day and cant seem to pull much more than 230 Kh/s (compared to the ~700 Kh/s a real reference 7950 pulls).
Anyway I JUST figured this out so hopefully the dude from ebay I got these from plays nice, although If he ended up picking up a giant pile of these things being told they were all 7950s I do feel bad for the guy...
Anyway my suggestion is if you DO end up reading this thread is to get rid of them, plenty of REAL 7950s/7970s out there.
I also think there may be a few more people out there who may find themselves in the same boat as I JUST received a PM from someone with the exact same issue not more than 18 hrs after bumping this 3+month old thread...Edited by WalkerYYJ - 11/7/13 at 12:06am
