Random access memory (RAM) is a vital part of any computer. It holds data that the processor is currently using, and its speed plays a big role in how well your computer performs. One key aspect of RAM speed is its frequency, measured in megahertz (MHz).
Knowing your RAM frequency can be helpful for several reasons. If your computer runs slowly, you can check if your RAM performs at its expected speed. Additionally, it’s essential to know your RAM frequency if you plan to overclock your system.
This article will explain how to find your RAM frequency using various methods. We’ll also check into what RAM frequency is and why it matters.
Query the RAM frequency with Powershell.
In simple terms, I use Windows Management Instrumentation (WMI) and Powershell to access pre-defined queries. This allows me to work with the values in scripts or perform calculations. The specific command I use is “Get-WmiObject.”
But I can use a short one-liner if I only need to get information about the RAM modules. This one-liner displays details like the channel, slot, capacity (in bytes), and speed for each individual module.
Get-WmiObject -class "win32_physicalmemory" -namespace "rootCIMV2" | ft BankLabel, DeviceLocator, Capacity, Speed
Query RAM frequency of all Windows devices
Since this is a common request, you can use this simple command to check the RAM module speed on any Windows computer, including physical servers. Note that for virtual machines, it will only show the capacity of the RAM.
Other values can also be output using the same query:
- Manufacturer = manufacturer of the RAM module
- SerialNumber = serial number of the module
- PartNumber = part number/article number of the manufacturer
For example, if you need the information to expand the main memory, this command should supply all the necessary parameters.
Get-WmiObject -class "win32_physicalmemory" -namespace "rootCIMV2" | fl BankLabel, DeviceLocator, Capacity, Manufacturer, Speed, SerialNumber, PartNumber
Check RAM frequency from remote computers.
The whole thing works remotely with the additional “-ComputerName“parameter on other computers. You can query information about the RAM of other Windows computers within seconds.
Get-WmiObject -ComputerName xxx -class "win32_physicalmemory" -namespace "rootCIMV2" | fl BankLabel, DeviceLocator, Capacity, Manufacturer, Speed, SerialNumber, PartNumber
