A stress test better than IBT / Prime95? Just been doing a little MD5 cracking on here and came across a bruteforce tool called MDCrack 1.8. Runs in DOS and my god it stresses your machine 2/3x as bad as IBT or Prime95. Rendered my machine basically unusable during the time its running. Worth generating an MD5 and trying to crack it, something 9-10 chars would stress test your PC for a good few days. Keep a watch on the temps, they went the highest I've seen... Hopefully recommending this isn't against the rules! To run the app use: MDCrack-sse --algorithm=md5 MD5HASHHERE This brought a i7 @ 3.8Ghz to it's knees!
