1066MHz is 1:SLIGHT overkill, and 2:simply OC'd 800MHz with relaxed timings!!
oh well no use crying over spilt potion...
lol my 7600GS OC'd 50% with the stock fan!! it plays everything i throw at it! (luckily i think crysis is a sh!t game...) so i wasnt flaming u or anything lol :P
so NOW, what you do is make the timings 4-4-4-12, put the FSB at 400MHz and first off, lower the cpu multiplier to 7, then increase to 8 if stable :P hope it works! wonder y no one else has posted to this thread in a while lol
