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. Also note that the memory is inter-
leaved to improve performance (see step 1).
1. The memory scheme is interleaved so you must install two modules at a time,
beginning with DIMM #1A, then DIMM #2A and so on. For optimal performance,
install four modules at a time of the same type and same speed. See the Memory
Installation Table on the following page.
2. Insert each DIMM module vertically into its slot. Pay attention to the notch
along the bottom of the module to prevent inserting the DIMM module incor-
rectly.
3. Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules (see step 1 above).
Note: Each processor has its own built-in memory controller, consequently each
CPU has a four-slot memory bank associated with it. (Memory installed into a
bank with no CPU present cannot be accessed.) 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.
Notes: the external SCSI port is included on the 6015X-8 only.
The external SAS port is included on the 6015X-3 only.
