Memory Support
The X7SB3-F supports 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 DIMM1A and DIMM1B and/or DIMM2A and
DIMM2B 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
Insert each DDR2 memory module vertically into its slot, starting with DIMM 1.
#1A. Pay attention to the notch along the bottom of the module to prevent
inserting the module incorrectly.
Gently press down on the DIMM module until it snaps into place in the slot. 2.
Repeat for all modules. (See support information below.)
To enhance memory performance, install pairs of memory modules of the 3.
same type and of the same, beginning with the blue slots (DIMM1A and
DIMM1B) and then the black slots (DIMM2A and DIMM2B).
Notes
Due to OS limitations, some operating systems may not show more than 4 GB of
memory.
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.)
!
CAUTION! Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage.
