That `sudo dmidecode' command in my Ubuntu Linux box did the trick.. I now know much more about my hardware than I ever cared or wanted to. Good stuff. :) You guys rule.

Using "dmidecode --type memory" limits the output. Not entirely sure it tells me exactly what I should order however... Works for opensuse 10.3 . Using “dmidecode –type memory” limits the output.

Supposedly DDR3 will support something similar to this, as does ECC ram. lshw and dmidecode to odd things on older boards, like list a 32MB pc100 as:

I upgraded my Dell Inspiron 500m from 512 to 1024 Mb, but there's errors on one of the blocks, so now I again run on 512. :-( Well, what I was actually searching for was a tool that could scan the RAM-block - and possible map out bad-blocks like on harddisks - if there's any such thing possible. But then I instead - at last - got another problem solved instead - with dmidecode: What is the max amount of RAM, my laptop can handle? Some say 1GB, some 2GB - even Dell's own homepage conflicts on this issue (and with the manual)! Thanks again! Just added "dmidecode" to my "Special Linux Commands" doc. :-) Thanks a lot! dmidecode is just perfect on CentOS 5 on my laptop!

I was trying to figure out how many RAM banks i had in a co-located rack server that i absolutely could not shut down. Thanks for the dmidecode info.

For what it's worth, dmidecode works great with Redhat Enterprise Linux 3 (RHEL3), too. Thanks for the info! For what it’s worth, dmidecode works great with Redhat Enterprise Linux 3 (RHEL3), too.
