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).
DIMM Installation (See Figure 5-3)
1. Insert the desired number of DIMMs into the memory slots, starting with slot
DIMM#1A and DIMM#2A. The memory scheme is interleaved so you must install
two modules at a time. See the memory confi guration chart below.
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 incorrectly.
3. Gently press down on the DIMM module until it snaps into place in the slot.
Repeat for all modules (see step 1 above).
Memory Support
The X7DBU supports up to 32 GB of ECC FBD (Fully Buffered DIMM) DDR2-667
