Other Notes and Restrictions
•
For the memory modules to work properly, please install DIMM modules in pairs
(with even number of DIMMs installed).
•
All channels in a system will run at the fastest common frequency.
•
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 follow-
ing table for details.
