I want to view the memory bandwidth of the installed physical memory on CentOS and Ubuntu. How do I do that? Thanks!

You could install dmidecode on CentOS (not sure about Ubuntu) and then as root call dmidecode --type 17 then look through the out to see the kind of ram you have. Though beware, ive experienced it not being 100% accurate.

An alternative way to do it would be to run a benchmark. Stream benchmark can work on CentOS.
