When monitoring my system with top, I noticed that under RES some values have a 't' suffix, but I can't see any indication of what this means.

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND

For example the top 2 processes have a value of RES of 0.012t. The 5th is using 5.534 gigabytes which is clear.

Can anyone give me an explanation?

"t" == Terabytes. Move the decimal three places to the right, and you have 12GB.
