No, the issue is that manufactures advertise in *1000, while computers use
bytes in *1024. The recent convention that's come into place to represent this
is between Kilo/Mega/Giga-bytes (*1000) and Kibi/Mebi/Gibi-bytes (*1024).
So a stick of memory advertised as 4 Gigabytes is going to present itself to
your computer as 3.84 Gibibytes, roughly.
