To find out what RAM you have, you can use the following methods:
-
Windows: Press Ctrl + Shift + Esc to launch Task Manager. Select the Performance tab to see current RAM usage displayed in the Memory box, and total RAM capacity listed under Physical Memory. Alternatively, you can open the Settings app, click on System, and then click on About to view your installed RAM. You can also use third-party software like CPU-Z or Speccy to get more detailed information about your RAM.
-
Mac: Open the Apple menu and select About This Mac. Next to Memory, you’ll see the amount of RAM your Mac has and its specifications.
Once you know how much RAM you have, you can determine the type of RAM you need if you want to upgrade. DDR3 and DDR4 hardware are incompatible, meaning DDR4 RAM will not be compatible with a motherboard slot made for DDR3 or DDR5. You can find the type of RAM you have by using third-party software like CPU-Z or Speccy.
