Raspberry Pi 3. Low than expected RAM ?

steveh2016 · July 11, 2016 at 2:00 PM

I'm currently running LE on a Pi 3 and noticed that the total RAM reported by free -m was only showing 736M. This seems low for a board specced with 1G of RAM. Is the RAM used elsewhere i.e. video memory etc ?

This is what free -m reports on a Pi 3:-

total used free shared buffers cached
Mem: 736 319 417 5 38 139
-/+ buffers/cache: 140 595
Swap: 0 0 0

This is probably the case.

OK, I've managed to find the info now. The full 1G is split between GPU and CPU and the split is configured in /flash/config.txt using the gpu_mem setting.
On the OpenELEC forums it states that 320M is the default, so that kind of fits what I'm seeing.
