maybe your vcore is too high... i ran prime at 2.6 gigs for 26 hours or so using a divider on my a8v vcore at 1.45. havent managed that on my neo2 when i run my memory 1:1 , runs for 6 hours or so only
have you enabled the agp lock ?
err take a bit slow.. it wont work at 300 mhz out of the box.. set it lower and increment bit by bit
