My first go at overclocking graphics cards
what i got so far:
Fairly good imo, its on stock cooling with fan at constant 80%.
Sadly i couldn't push the memory for 1000 like many others, kept artifacting.
Core could be pushed to 700mhz but would crash after 2 mins stress test in ATI Tool (Guessing not enough voltage). Got shader to 1700ish but again artifacting.
Load Temps Peak at 71*c
Edit: Lowered shader from 1655 to 1620, was getting smallish artifacts
! Seem's perfectly stable now
