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, 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. 128 MB, 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.
*With Opteron 246 C-stepping CPUs and above.
Support
The H8DCR-3 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. However, 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. See charts on fol-
lowing pages.
