Hello,
the naming of the DIMMs is somehow defined by JEDEC (as the spec is also defined from this group).
I have to admit, even participating in the specificaiton I don't remember what the PC stands for :-( ...
But my guess it is really Personal Computer as name for a class of PC's which includes Desktop, Laptop, Server and Workstations that can use this type of memory.
There are other modules specifiec that area e. g. called EP2 (32bit DDR2 SO-DIMMs), or EP3 (72bit DDR3 SO-DIMM). In this case the EP is not used consistently accross the memory generations, but it was ment to stand for "Embedded Product". These just have different requriements as PC's
On the JEDEC website one can download the accurate naming convention scheme (free registration required).:

This explains the full DDR3 (PC3 ..) naming convention that can be on a DIMM Label:
ggggg eRxff PC3v-wwwwwm-aa-bb-ccd
But if you take a look this document is already from 2009 .. .So either it did not requrie and update or JEDEC does this kind of naming specifications not really with a high priority ;-)
Best regards
Hermann
