How do I tell how much memory my Pi has?

How do I realize how much memory I have?

[bensimmo]

with Raspbian installed?

type pinout at the command line (terminal).

A Pi4 without Raspbian installed (no Operating System), you'll need to read the chips.
Pi3(+) it is 1GB
Pi Zero(W) it is 0.5GB

How do I realize how much memory I have?

And without an Operating System installed, read the documentation provided by Raspberry Pi themselves..

If it's brand new in the original packaging...read the box.

The free command gives you memory stats too

Code: Select all

pi@BlackPi:~ $ free
              total        used        free      shared  buff/cache   available
Mem:        3946976      285120     3278608       55416      383248     3481132
Swap:        102396           0      102396

The total figure is your physical memory minus the amount reserved for the GPU, in bytes.

If it;s fully up to date, take out the SD card and reboot. Diagnostics screen should tell you. Must be connected to an HDMI display.

Pi4 only.

Tru dat.

Wow. Totally missed that. Here's how it looks like in case anyone hasn't seen it before:

Yet another new feature/change that seems to have only be publicised by accident

Agreed. It would be great to have some centralized feed of those awesome improvements that constantly pop up in firmware/eeprom/Linux commits as well as the forum. The rest of the eeprom improvements made along the diagnostic screen are pretty great as well.

This goes with getting all of the funky hidden config.txt options published. There's no sensible reasons for keeping them opaque.

I suppose we probably should put an announcement in the announcement page. And update some docs somewhere. WIll take a look next week.

Updates to beta release are published in the release notes when the binaries are pushed to git. In the last bootloader related announcement there was a link to the release notes.
Unfortunately, the thread was drowned in the noise about release names.

Official documentation follows after that and is updated depending on the results of the beta e.g. the feature might get reverted or configuration options changed.

The HDMI diagnostics screen is only available in beta-image and I wouldn't recommend that end-users install a beta for an error screen which they should never see.

OK, so have checked and this bootloader is still beta software, not officially released, which is why there is no official announcement or documentation. You should only be seeing it if you have enabled the beta firmware downloading option.
