I use a tool called memconf which gives this information.

You can get memconf from

http://www.4schmidts.com/unix.html

It gives output like this:

It also has a verbose mode which gives basic OS info (distro, arch, kernel).  It 
puts all relevant information I typically need in one easily human digestable 
format, so I hardly use other utilities anymore.

I've used it on Solaris and Linux for a long time.  Not entirely sure how it 
gets this information, but it's written in perl, so you should be able to dig 
out it's methodology.  It appears to be using dmidecode though, so if you still 
wanted just plain dmidecode, it appears you probably can do that.
