weird thing here. I noticed my Pi model 2B is reporting a smaller amount of available RAM than before (~700Mb vs 1Gb).

[root@raspberry ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:            679         166          33           1         479         498
Swap:             0           0           0
[root@raspberry ~]#

Is my RAM module degrading over time? Is this a known issue with older Pies? Thanks

    OMG you are right. I am so silly. That "missing" memory is assigned to the GPU. Thanks

@goldilocks gave me the answer. That "missing" memory is just assigned to the GPU

    Note: In most cases, the CPU/OS will not be able to handle deffective RAM gracefully. It will just randomly crash or not boot at all.
