Add memory 

$ crc stop
INFO Stopping kubelet and all containers...       
INFO Stopping the instance, this may take a few minutes... 
Stopped the instance
dave@fedora:~/Downloads$ crc config set memory 14336
Changes to configuration property 'memory' are only applied when the CRC instance is started.
If you already have a running CRC instance, then for this configuration change to take effect, stop the CRC instance with 'crc stop' and restart it with 'crc start'.
dave@fedora:~/Downloads$  crc config set enable-cluster-monitoring true
Successfully configured enable-cluster-monitoring to true
