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 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.
