However, I would like to see S&M (from testmem.ru) included. I have used it to diagnose several elusive CPU and memory instabilities that Prime95 and Memtest86+ could not find, even after days of continuous testing. I haven't found any single program that is as strenuous.
Edit: I should note that S&M does not seem to work correctly with Vista.
...rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add 'within the limits of the law,' because law is often but the tyrant's will, and always so when it violates the right of an individual. -- Thomas Jefferson
