Memory
CAUTION
Exercise extreme care when installing or removing memory modules
to prevent any possible damage.
1. Insert each memory module vertically into its slot, paying attention to the notch
along the bottom of the module to prevent inserting the module incorrectly (see
Figure 2-2). See support information below.
2. Gently press down on the memory module until it snaps into place.
Note:
each processor has its own built-in memory controller. 512 MB, 1 GB, and 2
GB memory modules are supported. It is highly recommended that you remove the
power cord from the system before installing or changing any memory modules.
Support
The H8SMU supports single or dual-channel, DDR2-800/667/533 unbuffered ECC/
non-ECC SDRAM.
Both interleaved and non-interleaved memory are supported, so you may populate
any number of DIMM slots (see charts on following page).
Populating two slots at a time with memory modules of the same size and type will
result in interleaved (128-bit) memory, which is faster than non-interleaved (64-bit)
memory. See charts on following page.
Optimizing memory performance
For best results, populate slots in the following order: slot 1A then 1B then 2A
then 2B.
Maximum memory
: 8 GB.
