Determine Memory Type Without Opening The Computer

RAM Information Tools
With so many different types of RAM these days, purchasing a memory upgrade is not as easy as it used to be. Since there are so many different types, you will want to make sure you know what you need before you place your order. I would like to show you some quick ways that will help you to determine RAM type without even cracking the case.

Windows RAM Identifier

If you are running Windows you can download an app called System Information for Windows (this link takes you to a site you can download it from).

SIW audits your computer and gives you detailed information about your computer configuration. Although it has a wide variety of uses, it is great for getting information about your memory.

Standalone Memory Identifier

SIW is a standalone app so it can run from anywhere on your computer and even from your USB flash drive. To see your memory information, run SIW and click on “Memory” in the left hand menu.

Other options to check memory type

Another way to determine your memory type is to use the Crucial Memory Advisor Tool located at

An alternative is the Kingston Memory Search Tool at These tools allow you to either search by the computer manufacturer or by your motherboard manufacturer.

They also give you additional information like the maximum amount of memory you computer can use or how many memory slots your motherboard has. Even if you don’t want to purchase the memory from these sites, you can still use these tools as a reference to determine what type you need.

So there are several options to perform a memory type check. If you know of other ways to check memory type or possibly even an easier way please feel free to share your thoughts.

    How about using cpuz, a very nice tool. I even have repackaged it so i can run it directly from my u3 smart drive

    Also try- Create a new txt file on desktop, rename it” anything.nfo- (computername.nfo) open nfo file and there you have all the info about that PC that you need. I do this on any new server I set up and leave it on the desk top. if you add memory or anything- it will update when you open it

    That *.nfo file trick is interesting, though it would have been nice to have a little warning about the whole “possibly corrupt file or unrecognized version” warning box that pops up.

    Even so, a useful little thing to have.

      Haha, awesome! I love how the users always have the best methods, and I love all the other alternatives and work arounds. However, the tool is simple for non-techies as it singles out only the RAM in question. But that’s not me ๐Ÿ™‚

      Thanks guys!

      Scott… don’t respond if you don’t understand the english language. Type of memory refers to ddr3 etc. The op isn’t asking how much he wants to know what type. Your reply is of no help.

    on Linux,
    sudo dmidecode -t 17

    To get a nice printout showing how much memory is installed do this (all one line):
    sudo dmidecode -t 17 | awk ‘/Size:/ { if ($2!=”No”) memtotal+=$2 } BEGIN { memtotal=0 } END { print “Total memory: “memtotal” MB” }’

    Speccy is one of the better free products these days which allows you to find out a whole host of information about your machine (which having to open it up). It is created by Piriform – the same guys behind CCleaner and Defraggler so I believe it is a reputable program as well.

    I would also recommend CPU-Z. I have used it for quite some time and it is extremely easy to use (even for the computer newcomer).

    Looks like even though gtopala still lists a freeware version, there is no way to download the freeware version. I have been all over the sites pages that concern SIW and can’t find a freeware download.
