dmidecode.

I'm was going to upgrade the memory on my server and I was a bit unsure of which type of modules that was supported by the motherboard(DDR2/DDR3?). Couldn't find the manual or type of motherboard. And a second thing is that there is no monitor connected aswell. Well, this is how i solved that.

ssh server




sudo dmidecode --type 17 | more




And voilá!
