While you can find the total amount of physical memory, or RAM, installed on your computer from the Windows 8.1 Control Panel, you can get even more information, such as slot location and speed, by using the WMIC (Windows Management Instrumentation Command-line) command on an elevated Command Prompt console. If you have multiple memory modules installed on your computer, the Command Prompt console displays the information on each module separately. You can also use an alternate command, if you only want to check the total amount of physical memory installed.
Press "Win-X" to bring up the Power User menu, select "Command Prompt (Admin)" and then click "Yes" to open the Command Prompt console in elevated mode.
Enter "wmic MemoryChip get BankLabel, Capacity, Speed" (without quotes), then press "Enter." The Command Prompt console detects and displays the DIMM (dual in-line memory module) slot number, capacity (in bytes) and speed (in MHz) of each memory module on your computer. Alternately, type the command:
systeminfo |find "Total Physical Memory"
and then press "Enter" to get the combined amount of physical memory on all memory modules in megabytes.
Press "Alt-E" to exit the elevated Command Prompt console.
