23
FB-DIMM Memory
The Xserve (Late 2006) has 8 memory slots. The systems come with at least 1 gigabyte (GB) of
memory on two fully-buffered dual inline memory modules (FB-DIMMs). To improve performance
and capacity, you can install additional DIMMs for a total of up to 32 GB of memory. The 8
memory slots are labeled DIMM 1 through DIMM 8.

You can use the following memory in the Xserve (Late 2006):
667 MHz DDR2 ECC FB-DIMMs •
512 MB, 1 GB, 2 GB, or 4 GB in matching pairs (optimal, 4 or 8 identical DIMMs) •
36 devices per DIMM, maximum •
Error-correcting code (ECC) •
Important: Apple recommends that you use Apple-approved FB-DIMMS. Other FB-DIMMs might
degrade the performance of the Xserve. DIMMs from older Xserve systems are not compatible
with this Xserve.
Note: Before you purchase DIMMs other than those recommended by Apple, make sure that
the memory manufacturer conforms to the Joint Electronic Device Engineering Council (JEDEC)
specification. Make sure that the DIMMs support the correct timing modes and that the Serial
Presence Detect (SPD) feature has been implemented in accordance with the JEDEC specification.
To check DIMM compatibility, see the Macintosh Products Guide on Apple’s website at www.
