Just run a benchmark and compare with other 7970s users. If it performs the way it should then I wouldn't worry too much about it, otherwise you can try to flash to a standard 7970 bios or something.
Reference AMD &900 Series "Tahiti" with 768 Shaders????
Anyone ever seen anything like this? Is this card a fake, or is it a defective chip or something?
edit: was sold to me as a 7970, unbranded, no labels denoting HD 79XX...

I would return it, clearly the card isn't performing the way it should...

you can try flashing the bios for safest way for having a 7970 is returning it to the sellerOriginally Posted by Domino

Very odd indeed. Does it look like a reference 7970?
The Device ID 1002 679A is 7950, probably why [email protected] recognized it as such.Originally Posted by gboeds
Well, I have it folding at 1000Mhz, and it is getting about 1/4 the ppd as my other 7970....I think the shader count on GPU-Z must be accurate.
I have already contacted the seller for a refund, but I still am confused as to what this is? FAH recognizes it as a Tahiti PRO, which is a 7950, but it still is folding at about 1/3 of what I would see from a 7950.

I don't think that is the case, because it's not Pitcairn, it still shows as Tahiti, but it could be something similar to the card in that article. Maybe an ES 7950 with only 768 shaders.Originally Posted by cam51037
Sounds also that it might be a 7790 flashed to a 7970 BIOS.
Definitely interesting, can you maybe post some pictures of the card itself?
Edit: OP, it might be a kind of 7850 type card, read here: http://www.tomshardware.com/news/Pitcairn-radeon-HD-7850-768-shaders-gpu,15524.html
Sounds like you have a 7850 768 shaders edition, and unreleased card, or possibly an early model of a 7790.
But OP, if you don't mind me asking, didn't you notice right off the bat? 7850's and down all have a single PCI-E power connector, unlike 7870's or higher with dual power connectors. That is if this card turns out to be this 768 core 7850.

Like I know you can flash a GTX 680 to a GTX 770, which is a GK110 card (if I'm not mistaken) and adds extra features to it like a temp target, couldn't that have been done here as well?
But couldn't you flash the BIOS so it says that it's a different card?Originally Posted by anubis1127

GTX 770 is GK104, same as 680.
You could flash a Pitcairn with a Tahiti bios, but I doubt the card would work after that.Originally Posted by cam51037

it is now packed for shipping and taking it to UPS to ship back this afternoon, have already gotten agreement from seller for 100% refund (bought on E-Bay)
Definitely looks like a 7970/7950, it not having the model on the card is what made me open GPU-Z immediately on installing the card, and I found what I found....
HWInfo says it's a 7950, too....

it is a ES of 7950![tongue.gif]()
or an ES 7970 flashed with a 7950 BIOS!Originally Posted by healey33
The 7950 (Tahiti Pro) has two 6-pin PCIe power connectors. I see that yours has one 6-pin and one 8-pin - this is consistent with the 7970 (Tahiti XT). It may have been flashed with a 7950 bios?
EDIT: The P/N is difficult to make out but it looks like 102C386#### which is Tahiti. Also, it has 3GB of SDRAM which was only available on Tahiti boards as far as I know
That makes sense, right?

Yes, most likely! The only strange thing is the sticker. That is a production sticker - the engineering samples have different ones (they say engineering sample on them amongst some different numbers). ES's do not have a S/N :SOriginally Posted by gboeds
