I've got this Terratec 5900 ultra that has been flashed to 5950 ultra. I bought it seconhand, and the guy I bought it from told me that the original card had core/memory speeds of 500/850, I think, and that after the bios flash the speeds were 475/950. Now, the memory is indeed at 950, but the core shows only 300! First I thought that the software was only reading the card incorrectly, but after I unlocked the coolbits overclocking capability for Nvidia's own overclocking system, it still showed the core speed at 300, And it's kind of unlikely that Nvidia's software would have any problems reading the card's specs. Anyone have any ideas? I'm going to start overclockin the card soon, and I want to be sure I wont fry the card, considering that my goal is to up the core speed by about 200mhz!
