5-6 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, beginning with CPU1 slot 1A,
then 1B, etc.. Pay attention to the notch along the bottom of the module to prevent
inserting the module incorrectly (see Figure 5-4). 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 CPU2 DIMMs can-
not be addressed if only a single CPU is installed. 128 MB, 256 MB, 512 MB, 1
GB and 2 GB* memory modules are supported.
*With Opteron 246 C-stepping CPUs and above.
Support
The H8DSR-8 supports single or dual-channel, registered ECC DDR400/333/266
SDRAM.
Both interleaved and non-interleaved memory are supported, so you may populate
any number of DIMM slots (see note on previous page). The CPU2 DIMM slots
can only be accessed when two CPUs are installed (however, the CPU2 DIMM slots
are not required to be populated when two CPUs are installed).
Populating two adjacent 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.
