I have model B with 512 MB of RAM, but htop displays
pi@raspberrypi ~ $ free -h total used free shared buffers cached Mem: 231M 214M 16M 11M 16M 105M -/+ buffers/cache: 92M 139M Swap: 481M 0B 481M
gpu_mem is set to 16M
I'm using wheezy image which is upgraded to jessie, but problem was also on wheezy. How to enable all 512 MB?
*Model B rev2, I know because of "Made in UK" and copyright date is 2011.12
