how do i specify the RAM information of my device

Hi, I'm Rodrigo and I will help you.
Depending on the information you need about the RAM, you can find it by right-clicking the Start Menu icon > System.
Or on the Task Manager, right-click in a blank area of the taskbar > Task Manager > Performance tab > Memory

Press Windows + R, type dxdiag, hit Enter

On the "System" tab, look for "Memory"

Alternatively:

Press Ctrl + Shift + Esc → open Task Manager.

Select Performance → Memory.

Look for Memory/total capacity

You can also see the speed and whether/how much memory is in use.
