Help- Detecting free memory slots on motherboard
I need to determine if I have any free memory slots and was wondering if there is a command or utility that I can use to do this without cracking the case?
I am running RHEL ES3 on an IBM HS20 Blade. Thanks for any help. |
absolutely there is a command that will show you this info.. it's lshw
Scroll down to see what Slots are full of How much memory.. Code:
mail:~# lshw -C memory lshw is not installed by default on RedHat if I recall, so you will probably have to install it. |
Oh man this is EXACTLY what I was looking for! Thank you SO much!
Now...do I install lshw from an install disk? (sorry...extreme newbie here). |
There is a command in debian that may or may not be present in Redhat. in debian it must be run under Super User.
dmidecode -t memory when run should look something like this... Quote:
Associated Memory Slots, tells you how many slots are present, and their identifiers. you can then see those identifiers in the blocks that reference that specific slot on the motherboard Installed Size and Enabled Size would read NONE if there was not a memory module present in that slot. be careful about the Maximum Memory Module Size and Total Memory Module size info. I know for a fact that My Motherboard can only support two one gigabyte sticks of ram. for a total of two Gigs. I don't know where my system got 4gigs a stick for maximum of 8gigs. maybe thats the capability of the memory controller itself and there are other limitations on the motherboard that impose a 2gig maximum on the slots. but just be careful when using this information to select memory to add to the system. best to pop the case, identify your motherboard and look it up before investing any money. Hope this was helpful; Tim |
dmidecode should be on the redhat system by default, and will provide the requested info, but I find the output of lshw so much easier to read..
Not a big redhat users but wouldn't you install lshw with yum ? yum install lshw |
Thanks guys! Both suggestions will help.
Like I said before, I am an extreme Linux newbie. This is on an enterprise server and it doesn't look like yum is installed. I will be installing lshw from an rpm. Thanks again! |
other option. .
up2date lshw or download the proper package manually and install with rpm.. http://dag.wieers.com/rpm/packages/lshw/ |
