Installing Memory
Memory Support
The X7DCL-3 supports registered ECC DDR2-667 or DDR2-533 SDRAM. The
memory scheme is interleaved, so you must populate two slots at a time, beginning
with slot 1A and 2A, then slots 1B and 2B and finally slots 1C and 2C. You may
populate any even number (2, 4 or 6) of DIMMs. See the chart below for optimizing
your DIMM installation. See web site for details on supported memory.
Installing Memory Modules
1. Insert the desired number of DIMMs into the memory slots, starting with
DIMM #1A. The memory scheme is interleaved, so you must install two
modules at a time, beginning with slots 1A and 2A, then slots 1B and 2B,
then slots 1C and slot 2C. See the Memory Installation table below.
2. Pay attention to the notches along the bottom of the module to prevent inserting it incorrectly.
3. Gently press down on the DIMM module until it snaps into place in the slot
(see Figure 5-3).

Notes: 1. DIMM slot# specified = DIMM slot to be populated. “---“ = DIMM slot to be left
unpopulated. 2. Both DDR2 533 MHz and 667MHz DIMMs are supported; however, you
need to use the memory modules of the same speed and type.
