The four memory riser cards that you received with your computer are connected together in sets of two. Do not attempt to disconnect the memory riser cards
from each other. Each memory riser card is numbered in the upper left hand corner. These numbers indicate which DIMM slot on the system board each riser
card must be inserted into. Only the DIMM_1-4 slots (the slots with the white securing clips) on the system board can be used with the riser cards. The other
slots (DIMM_5-8) must be left vacant.
