Memory Support
The X7DBE+/X7DB8+ supports up to 64 GB of FBD (Fully Buffered DIMM) ECC
DDR2-667/533. Populating with pairs of memory modules that are of the same
size and same type will result in interleaved memory.
Note: Due to OS limitations, some operating systems may not show more than 4
GB of memory. To optimize memory support, follow the table below for memory
installation:

Notes: i. DIMM slot# specified = DIMM slot to be populated; "---" = DIMM slot not to
be populated. ii. Both FBD 533 MHz and 667MHz DIMMs are supported, however
you need to use memory modules of the same speed and type. iii. Interleaving
memory is supported when pairs of DIMM modules are installed in both Branch 0 and
Branch 1. Interleaving memory is not available if only 2 DIMMs are installed. 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
notches.
To Remove: Use your thumbs to gently push each release tab outward to free the DIMM from the
slot.
