Not as bad as yours, but still rather hot -- enough that I can only
rest a finger on the heat sink for a few seconds. And I though my R-Pi 3B
running at 50degC was high. I ordered through Newark -- if that has any
relevance.

Interesting -- mine shows
debian@beaglebone:~$ free -h
total used free shared buff/cache
available
Mem: 610M 194M 97M 26M 318M 377M
which is NOT some common power-of-two, and is also much less than I'd have
expected even if the graphics system is using part of it (300MB for
graphics buffering?)
