Figure 5-3. Installing a DIMM into a Slot
To Install: Insert module vertically
and press down until it snaps into
place. Pay attention to the bottom
notch.
Memory Support
The X7DBR-8 supports up to 32 GB of ECC FBD (Fully Buffered DIMM) DDR2-
667 or DDR2-533 SDRAM. The memory is an interleaved confi guration, which
requires modules of the same size and speed to be installed in pairs. You should
not mix DIMMs of different sizes and speeds. See Figure 5-3 for installing memory
modules.
Note: Notch
should align
with its
receptive point
on the slot

Notes: i. DIMM slot# = DIMM slot to be populated; “---“ = empty DIMM slot. ii. Both
FBD 533 MHz and 667MHz DIMMs are supported; however, you need to use
memory modules of the same speed and type on a motherboard.
iii. Interleaved
memory is supported when pairs of DIMM modules are installed in both Branch 0
and Branch 1 . However, Interleaved memory is not available if only 2 DIMMs are
installed on the motherboard. iv. For memory to work properly, you need to follow
the restrictions listed above.
