Method 1: Check RAM Type Using Command Prompt
- Open Command Prompt.
- Run the following command:
wmic memorychip get SMBIOSMemoryType
The returned number corresponds to a memory type. On some newer systems, the value may be unavailable or generic.
Method 2: Use PowerShell
Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, Speed, Capacity, SMBIOSMemoryType
This command displays additional details about each installed RAM module.
Method 3: Use CPU-Z or HWiNFO
Free hardware information tools such as CPU-Z and HWiNFO can accurately identify:
- RAM type (DDR3, DDR4, DDR5)
- Memory speed
- Timings
- Voltage
- Channel mode
