It's not on Newegg anymore, they removed the listing entirely. Maybe they're not going to sell it anymore, I have no idea. Usually if it's just out of stock they leave it listed but as out of stock.
Anyways, I got mine today from Newegg and I'm testing it now. It looks like mine simply won't do a single mhz above the factory OC of 630, even at one ATITool OC uptick of 635 it locks up. However the memory seems to have some headroom, I had it up to 1094 before getting artifacts with the ATITool Artifact Tester. Since the stock Ultra is 2160 I have mine backed down to 1085 (2170) and it seems reasonably happy. I'm now in the process of doing a complete 30 minute ATITool Artifact Test to ensure this memory OC is OK.
My Foxconn actually has a black PCB, the same black PCB that Ultras have, instead of the standard green PCB that 8800GTS and GTX have. So I am guessing my GTX is a rebadged Ultra that possibly didn't pass QC as an Ultra and got clocked down to GTX speeds. I hope it can reach close to Ultra speeds on the memory.
I was curious about the default shader clock on this so I opened up nIbitor and looked at it and the shader clock is set to the GTX default of 1350. So this card is set in the BIOS to 630/1350/1000. Very interesting that Foxconn didn't bother to increase the shader clock. I may have to play with that later on, though I am somewhat leery of modifying and flashing the BIOS on my $520 videocard. Maybe a few months down the road when this card is being crushed by Crysis, I'll think it over. For now, I'll leave it be.
EDIT: I just checked Newegg and they have put the listing back! And it's still $520 AR. But it is out of stock now! Get on the Auto-Notify list now I guess if you want it still.
