Aida32 is by far my favorite sysinfo utility... It's free and there's not much that it won't figure out. Great to use when you wanna find out what's in the computer without popping the case and disassembling it... like trying to figure out what speed RAM modules you have. Instead of taking them out and trying to decode what's on the chips, just use AIDA and it reads the SPD (provided there is one). Also works great for finding out exactly what chipset the motherboard has (great for Dells, Compaqs, etc, which hardly ever really tell much). two thumbs up for AIDA32... hope he never decides to charge for it.
