I have a Yamaha 16x writer and was able to write at 16x all of the time, until I upgraded my gigabyte board to an abit kt7 raid. no i receive buffer under runs when copying at anything greater than 8x. I have updated/ flashed everything. I have tried using all ide channels for both the hd and writer (i'm writing from the hd). Any suggestions??

Thanx

System specks if they're any use:-
