X10SRL-F User’s Manual

Notes:

•Be sure to use memory modules of the same type and speed 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.
