2-4 Memory Installation
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 interleaved to improve performance (See step 1).
DIMM Installation
Insert the desired number of DIMMs into the memory slots, starting with 1.
P1-DIMM 1A. For best memory performance, please install memory modules
of the same type and same speed on the memory slots as indicated on the
tables below. (See the Memory Installation Table Below.)
Insert each DIMM module vertically into its slot. Pay attention to the notch 2.
along the bottom of the module to prevent inserting the DIMM module incor-
rectly.
Gently press down on the DIMM module until it snaps into place in the slot. 3.
Repeat for all modules.
