Ok i have a Gainward gf4 ti 4400 128mb ddr golden sample. Now when i used riva tuner it has 2 optiosn to use when overclocking ... either threw low level system settings or threw the detonater drivers. Now which way would be better to use? And anyone else have any experiances with the make and model of my card??... have any idea of what kind of oc i should expect...
