My card easily does U speeds, but would probably gain a bit from increased Volts.
The main problem with flashing a 5800nu to a 5800u would likely be a clash with memory types. Doesn't a 5800u use DDR3, and not sure what your 5800nu has ???
However, you could probably get more Core speed from your card by modding your bios to set GPU volts at 1.5, instead of its norm of 1.4v !
All you should have to do is use X-Bios editor and look for gpu volts look-up table binary string of "78 04 82 05 8C 06" and change it to "78 04 82 05 96 07".
Or of course, you could just use NiBiTor 1.8 and at "VID Mode" tab, set Voltage 3 to VID 7 !
However, remember whatever you do will likely increase temps. And good temp control was never a plus point with a 5800 card ??
