Notes:
•
Be sure to use memory modules of the same type, speed, and frequency
on the same motherboard. Mixing of memory modules of different types
and speeds is not allowed.
•
Due to memory allocation to system devices, the amount of memory that
remains available for operational use will be reduced when 4 GB of RAM
is used. The reduction in memory availability is disproportional. See the
following table for details.
