5-5 Installing
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, so the CPU2 DIMMs
cannot be addressed if only a single CPU is installed. 256 MB, 512 MB, 1 GB, 2
GB and 4 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 H8DMU+ supports single or dual-channel, DDR2-667/533/400 registered ECC
SDRAM. Both interleaved and non-interleaved memory are supported, so you
may populate any number of DIMM slots (see note above and chart on following
page). The CPU2 DIMM slots can only be accessed when two CPUs are installed
