How to choose the right RAM?

Task Manager will give you the most info to buy compatible memory, but you need to know more. Take a pen and paper, and write down the total amount (4GB), type (DDR3), and Speed 1333 MHz. You will also see how many memory slots you have, and how many are available. On the picture, there are 2 slots and only one of them available.

Device maximum.

Your computer’s RAM is limited to not only the number of slots but also motherboard capacity. To find out the capacity, you need to find out your computer’s model first. Then go to the manufacturer’s website and find the documentation for your computer. The documentation will say the maximum amount RAM your device can work with. In my case, the maximum RAM amount is 8GB. That means if I add another 4GB stick, identical to the one I have, my computer will run faster and without any problems.

Operating system maximum.

However, your operating system also has a maximum capacity. First, you need to find out what operating system are you running. To do that, right click on My Computer or This PC, and click on Properties. Under Windows edition, it will show the operating system, and under System Type, it will if you have a 32- or 64-bit system.
Below are the RAM maximums for most common operating Windows versions.

  • Windows 7 32-bit – 4GB
  • Windows 7 64-bit:
  • Home Basic – 8GB
  • Home Premium – 16GB
  • Professional – 192GB
  • Enterprise – 192GB
  • Ultimate – 192GB
  • Windows 8.1 – 128GB
  • Professional 512GB
  • Enterprise 512GB

Since the computer that we are working with is running Windows 8.1, our limit is 128 GB. We are planning to upgrade to 8 GB, which won’t cause any problems.

One more thing.

However, there is one more thing that you should know: the bus specification. Some RAM labels show it, and it is better if you match it. To find it out, you should see open your computer and read the label on your RAML

  1. Turn off your computer.
  2. Unplug the power cable. Take out the battery if you have a laptop.
  3. Press and hold the power button for 30 seconds. Now your PC hardware is safe to touch.
  4. Find the RAM sticks and try to read the labels.
    You might have to pull one out. Usually, you will see the manufacturer (Samsung), type (DDR3), size (4GB), speed (12800R). You should do your best to match those, otherwise, your computer might not turn on with incompatible RAM. The best and safest way is to search and buy by the part number M378B5773CH0-CH9.
