RMC 7182
1U Rackmount System
Memory Support
The embedded system supports up to 16GB of DDR3 ECC UDIMM or up to 32GB of ECC DDR3
RDIMM (1333/1066/800 MHz in 6 DIMM slots.) Populating these DIMM slots with a pair of memory
modules of the same type and same size will result in interleaved memory, which will improve memory
performance.
When populating, install DIMMs to the "A" slots first. Install to the "B" slots only after all the "A" slots are
populated: 1A, 2A, 3A, 1B, 2B, 3B.
Maximum Memory Possible
Single Rank UDIMMs - 12GB (6x 2GB DIMMs), Dual Rank UDIMMs - 24GB (6x
4GB DIMMs)
o Both unbuffered ECC and non-ECC DIMM modules are supported by the motherboard. Using
ECC or non-ECC memory on your motherboard depends
on the CPU installed.
o Due to OS limitations, some operating systems may not show more than 4 GB
of memory.
o Due to memory allocation to system devices, the amount of memory that remains available for opera-
tional use will be reduced when 4 GB of RAM is
used. The reduction in memory availability is disproportional. Refer to the table below.
