5-5 Installing Memory
Note: Check the Supermicro web site for recommended memory modules.
CAUTION
Exercise extreme care when installing or removing DIMM modules
to prevent any possible damage.
1. Insert the desired number of DIMMs into the memory slots, starting with Bank1
of CPU1. Pay attention to the notch along the bottom of the module to prevent in-
serting the module incorrectly (see Figure 5-3). Note 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. 128 MB, 256 MB, 512 MB, 1
GB and 2 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. Using DIMMs of the same type and speed is recommended.
Note: the external SCSI port is included on the H8DMR-82 only.
