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.
apple.com/guide. You can purchase Apple-approved memory online from the Apple Store at
www.apple.com/store.
Installation Rules
You must install DIMMs in pairs, and the DIMMs in each pair must be identical (the same
size, speed, etc.). The first pair is installed in slots 1 and 2. Install the next pair in slots 3 and 4.
Subsequent pairs go slots 5 and 6, and then slots 7 and 8.

For Best Performance
For the best performance, use identical DIMMs in all slots and fill up slots 1 through 4 before you
install DIMMs in slots 5 through 8. If you don’t have eight identical DIMMs, install identical DIMMs
in slots 1 through 4 and a second set of four identical DIMMs in slots 5 through 8. If you can, after
you fill slots 1 through 4, add a full set of four DIMMs in slots 5 through 8 instead of just a pair in
slots 5 and 6.
Working Safely Inside the Xserve
Always touch the Xserve enclosure to discharge static electricity before you touch any
components inside the Xserve. To avoid generating static electricity, do not walk around the
room until you have finished working inside the server and have replaced the cover. To minimize
the possibility of damage due to static discharge, wear an antistatic wrist strap while you work
inside the Xserve.
Warning: Always shut down the Xserve and disconnect the power cords before opening
it to avoid damaging its internal components or the components you are installing. Don’t
open the server while it is turned on. Even after you shut down the Xserve, its internal
components can be very hot. Let it cool before you open it.
