How to tell which Raspberry Pi 4 RAM size do I have?

So...which Raspberry Pi 4 RAM size do I have?
If your Raspberry Pi is already up and running, you can easily check for the memory size within the OS (Raspbian or Raspberry Pi OS) by running the followig command in terminal:
free -h
However, if your Raspberry Pi is sitting in front of you right now, you can simply look at the marking on the RAM chip. Refer to the picture below (2GB version shown):
At the time of writing, the marking code is as follows:
- 1GB - 4HBMGCJ
- 2GB - D9WHZ
- 4GB - D9WHV
- 8GB - D9ZCL
Have fun!

Thanks, very helpful, especially the `free -h` command line tool
Thanks CR … you are awesome !!
Very helpful, I have 2 RPI4s 4GB and an 8GB. It was easy using your chart to identify the two boards, thank You!
Frustratingly unhelpful.
My RPi4 is in RAM chip occluding case. Your post hinted at, but did not deliver the technique “within the OS”
BTW: from within a Terminal… top
left most portion of the 4’rd line will be MiB Mem : XXXX.Y total
Thanks- extremely helpful in verifying what I thought I had.
