Well I know the NV40 is unlockable, don't know about the NV48. Maybe you should take a peek in Rivatuner although your Ultra card probably already has 16/6?

when it says that the nv48 is .11 process it means that he will get way higher clock speeds then the .13 process nv40 and you cant unlock it, it is already at 16/6 ,but you should be able to get at least 450core and 1300 mem on that sweet baby

All the 6800GT and 6800ultra cards are already at 16/6 with GDDR3. The 6800 is at 12/5 and the 6800LE 6800XT are at 8/4.
