2.1.2 Memory Modules
The RES-22XR3 supports memory according to Table 2-1 . Note the total memory
capacity varies according to the motherboard installed in the RES-22XR3.
When installing memory, follow these rules for best memory performance:
• Always start with P1-DIMM1A, the system will not boot if this DIMM Slot is
vacant. When populating DIMM modules always start with Channel 1 (P1-
DIMM1A and 1B) first. Always make sure total DIMM capacity meets the
minimal requirements of your OS.
• It is strongly recommended that you do not mix memory modules of different
speeds, sizes, voltages and vendors.
