WTF is the difference between:

DDR3 1866 (PC3 15000)
DDR3 1866 (PC3 14900)


And the follow up would be if my mobo/cpu can support DDR3 1866 - will it automatically handle either PC3 15000 or 14900?

I am not an expert...by any means. But will attempt to answer as best I can

The first # (DDR3xxxx) refers to the maximum clock speed the Ram can operate at (in this case, 1.866 Ghz.)

The second 3 (PCyyyy) refers the maximum transfer rate that the memory reaches, in MB/s

Clock speed is backwards compatible (Mobos can normally be throttled down in clock speed.) I don't think the data transfer limit matters....it should work, just at a bit slower transfer rate.

Best thing to do is check mobo documentation if you aren't sure.

The original Dance Dance Revolution had better songs. They started to get stupider with different releases. I seem to recall DDR3 was terrible.
