2-4 Installing DIMMs
Note: Check the Supermicro web site for recommended memory modules.
Warning: Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage. Also note that the memory
is interleaved to improve performance (see step 1).
Memory Support
This motherboard supports up to 8 GB Unbuffered DDR3 Non-ECC up to 1333 MHz
in 4 DIMMs or DDR3 Non-ECC 1600 MHz upto 4GB in up to 2 DIMMs memory
(See notes 2 and 3). Populating DIMM 1A, DIMM 2A, and/or DIMM 1B, DIMM 2B
with memory modules of the same size and of the same type will result in dual
channel, two-way interleaved memory which is faster than the single channel, non-
interleaved memory.
Notes:
Due to the OS limitations, some operating systems may not show more than 1.
4 GB of memory.
Both Unbuffered ECC and Non-ECC memory modules will boot up. How- 2.
ever, ECC functionality is not supported on this board.
X7SBU supports DDR3 up to 1600 MHz;. You can only install up to two 3.
1600 MHz modules with one module in DIMM1B slot or DIMM2B slot or
with two modules in both DIMM 1B and DIMM 2B slots
Due to memory allocation to system devices, memory remaining available 4.
for operational use will be reduced when 4 GB of RAM is used. The reduc-
tion in memory availability is disproportional.
For Microsoft Windows users: Microsoft implemented a design change in 5.
Windows XP with Service Pack 2 (SP2) and Windows Vista. This change is
specific to the Physical Address Extension (PAE) mode behavior which im -
proves driver compatibility. For more information, please read the following
