I flashed the BIOS using the X800XT.bin and could not load the Catalyst drivers to save my life. I re-flashed with my backup old BIOS and it's working great. It still say's I have an 800 Pro and not an XT or PE. 
Did flash with the wrong BIOS? How do I know I have the right one? I used

My Device ID = 4A49
Chip Type = R420
All help would be greatly appreciated...
*EDIT*  After re-reading the sticky, it says "Make sure you have 1.6ns Samsung GRam. ".... How do I find out if I have this or not, and if not, what can I do if anything?
