Memory Support
The X8STi 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.
Populating DIMMs
For memory to work properly, follow the table below for memory installation:
Memory Population (UDIMM Only Routing)

2 2 Unbuffered DDR3
(with or without ECC)

Maximum Memory Possible
Single Rank UDIMMs - 12GB (6x 2GB DIMMs), Dual Rank UDIMMs - 24GB (6x
4GB DIMMs)
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.
Due to OS limitations, some operating systems may not show more than 4 GB
•
of memory.
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. Refer to the table
on the next page.
