I've ben running this GPU tool on this 9800 Eco GT.
Defaults
Core Clock: 550MHz
Shader Clock: 1375MHz
Memory Clock: 1800MHz
overclocked
Core Clock: 680MHz - stopped when errors detected
Shader Clock: 1500MHz - I stopped
Memory Clock: 2200MHz - I stopped
Does this application actually work because the shader and memory tests just kept going and going
I saved the settings and ran crysis without any problems
