RMC 7130
1U Rackmount System
Memory Support
The X8STi/X8STi-LN4 supports up to 24 GB of unbuffered ECC or non-ECC DDR3
1333/1066/800 in 6 DIMM slots. Populating the DIMM slots with a pair (or pairs) of memory modules of
the same type and 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 op-
erational use will be reduced when 4 GB of RAM is
used. The reduction in memory availability is disproportional. Refer to the table below.
