i used powerstrip and set core 600 and mem 400 it was perfectly stable no problems at all. got a score of 97 on NTUNE. but then trial ended early for some reason? dont know why. so iam using atitool. but ati tool messes up at higher clock rates, example

find max mem - 345Mhz screen becomes unstable even with core still at 450, screen display "OUT OF RANGE"

Find max Core - 560MHz while mem at 250 and i get same problems screens starts ?vibrating?

i believe it has something thing to do with the divider? mem to core ratio? but iam no computer software speacialist.

using beta 13 on X1300 PCI-E 512 x16 with 64-bit OS SP1. please help

try reinstalling those heatsinks...I know that heatsinks sound all good, but a random short can KILL a good card.
