Any info on 512 meg 7900GTs?

So I was looking at cards in newegg and saw http://www.newegg.com/Product/Product.asp?Item=N82E16814130034
It's a 7900GT overclocked to 560/1500, but it also has 512 megs of ram. Looking around I found benchmarks of similarly clocked 256MB 7900GTs, but I'm having a hard time finding any with 512 megs of ram.

try finding a site that has a 7900gtx underclocked, that might be easier to find.
