Memory Support
The X7DB3 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 and removing
memory modules.

Number of Bank 1
DIMMs (Channel 0)
2 DIMMs 1A
4 DIMMs 1A
8 DIMMs 1A
Notes: i. DIMM slot# specified = DIMM slot to be populated; "---" = DIMM slot not to
be populated. ii. Both 667 and 533 MHz FBD DIMMs are supported, however, you
must 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. iv. For memory to work properly, you need to follow the
restrictions listed above.
To Install: Insert module vertically and press down until it snaps into place. Pay attention to
the bottom notch.
To Remove: Use your thumbs to gently push each release tab outward to free the DIMM from
the slot.
