So after my 4850 died the other day, I picked up a PNY Verto 9600 GSO OverClocked edition for a back up card. And since I have been using ATI for a while now, am not used to the slightly different setup to NVidia cards, shader clock overclocking and linking with core clock. Using the EVGA Precision tool I have been able to take the card from its stock clocks of 575/850/1438(core/mem/shader) to 615/950/1538 with the shaders and core linked. Anything over that and Vantage crashes with a driver reset. Now is this my max clock for the card or can I get it higher (barring and penil/hard mod, BIOS I will try) by unlinking the shaders and core. Thanks!
