no offense to the program but why are you trying to use it? For O/C ?
I have found it to work well on my machine, but others have issues as you're reporting. I do belive I seen once this question posted . I think the answer posted was to try the individual chipsets , 1 at a time untill it reads correctly. Altho I'm not sure if it is crashing B4 you see its window , or is it crashing when you're trying to raise the clocks. If its an instant crash it's most likely that the chip it uses is not supported by systool!?!
