Glad to know some of my brain cells are still working !
As I said, there was this vague feeling in the back of my mind that a 5800 used diff memory from a 5800u ------> which then obviously means you must not flash a 5800 with a 5800U bios !!!!!!
Also, I think DDR2 was supposed to be more overclockable and do more work per clock cycle, but don't believe it was found sufficiently successfull over DDR in vga cards to guarantee a future.
And although it is now becoming the in thing for new generation mobo main RAM, it is still proving less effective than DDR untill running at higher speeds, simply because the DDR2 ram chips have a higher built-in latency.
