[SOLVED] How I find true RAM speed?

[Daniel8]

Hi, how do I find my true RAM speed? Task manager shows me 2400MHz, while cmd shows me 2666MHz. How task manager, cmd and cpu-z know RAM speed? Do they measure it or do they read it from some data?

I have Asus TUF GAMING fx505dt, Ryzen 7 3750h, so it should oficially support 2400MHz, but some sources says 2666MHz. I have HyperX 2666MHz with auto XMP or something like this, but my laptop doesn't have XMP option in BIOS.

Thank you.

sound like the ram is 2666 but running at 2400.

Open Powershell and run the following:

Get-WmiObject win32_physicalmemory | Format-Table Manufacturer,Banklabel,Configuredclockspeed,Devicelocator,Capacity,Serialnumber -autosize

Or, more specifically:

Get-WmiObject Win32_PhysicalMemory | Select-Object Speed
