Installing Memory
CAUTION! Exercise extreme care when installing or removing DIMM
!
modules to prevent any possible damage.
Memory Support
The X7SBi supports dual or single channel, ECC/Non-ECC unbuffered DDR2-
800/667 SDRAM. Both interleaved and non-interleaved memory are supported,
so you may populate any number of DIMM slots. (Populating DIMM#1A/DIMM#2A
and/or DIMM#1B/DIMM#2B with memory modules of the same size and type will
result in two-way interleaved memory, which is faster than single channel, non-
interleaved memory.) Note that when ECC memory is used, it may take 25-40
seconds for the VGA to display.)
Installing Memory Modules
1.
Insert each DDR2 memory module vertically into its slot, starting with DIMM
#1A. Pay attention to the notch along the bottom of the module to prevent
inserting the module incorrectly.
2.
Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules. (See support information below.)
3.
To enhance memory performance, install pairs of memory modules of the
same type and of the same, beginning with DIMM #1A and DIMM #2A, then
DIMM #1B and DIMM #2B.
Notes
Due to a chipset limitation, 8GB of memory can only be supported by the following
operating systems:
•
32-Bit: Windows 2000 Advanced Server, Windows Server 2003 Enterprise Edi-
tion;
•
64-Bit: Windows Server 2003 Standard x64 Edition, Windows XP Professional
x64 Edition, Windows Server 2003 Enterprise x64 Edition
Some old-versions of DDR2-667 may not match Intel's On-Die Temperature require-
ment and will automatically be downgraded to run at 533 MHz. If this occurs, contact
your memory vendor to check the ODT value.
Due to memory allocation to system devices, memory remaining available for
operational use will be reduced when 4 GB of RAM is used. The reduction in
memory availability is disproportional. (Refer to the Memory Availability Table
below for details.)
