how do i tell what type of ram is in my pc?

Want to add another stick of RAM to my desktop but I've no idea if it's DDR4 or DDR5, or what speed it runs at. Task Manager shows 16GB and that's about it. Is there a way to see the exact type without opening the case?

Task Manager > Performance > Memory shows the speed and how many slots are used, but it doesn't always say DDR4 or DDR5. CPU-Z is the easy way, Memory and SPD tabs show type, speed and the exact part number of each stick. Or in PowerShell run Get-CimInstance Win32_PhysicalMemory | Select SMBIOSMemoryType, Speed. 26 means DDR4, 34 means DDR5, 24 is DDR3.
