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. "---" indicates an unpopulated DIMM slot. ii. All memory modules must be of the same speed
and type. iii. Interleaved memory is supported when pairs of DIMMs are installed in both Branch 0
and Branch 1. Interleaved memory is not available if only 2 DIMMs are installed.
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.
