Installing Memory
Exercise extreme care when installing or removing memory modules
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 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, 2 GB* and 4 GB* memory modules are supported.
*With Opteron 246 C-stepping CPUs and above.
Support
The H8DAR-T 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).
