Note: The KGen referred to was discussed in another forum. I could not tell you how accurate it is because I have not used it for that purpose. Out of curiousity, more than anything, I started playing with it to see what all the fuss was about and I noticed several things... This program basically runs some sort of checking and iteration to generate some numbers. I have found that whenever you run the program (say through 20+ cycles) your PROCESSOR IMMEDIATLY starts working at 100% and stays there for as long as the program runs. It really gives the puter/processor/memory a workout. I have several machines and it is a very reliable benchmarking tool when used to compare the speed/memory differences between machines. It is also VERY USEFUL in checking your systems ability to function after 'tweaking'-- especially in overclocking and memory tweaks. And you get results fairly quickly. You will max out your processor temp within 3-5 minutes (Great for checking your cooling measures). In my case any instability in my system shows up withing 5 minutes--either with a lockup or error message. I don't know if this is useful for any of you but I thought I would throw it out to you. Its kind of interesting to see how your "pride and joy" holds up to a real workout.
