Chapter 2 Installing or Replacing Components 35
Installation Rules
You must install DIMMs in pairs, and the DIMMs in each pair must be identical. The first
pair is installed in slots 1 and 2. Install the next pair in slots 3 and 4. Subsequent pairs
go in slots 5 and 6, and then slots 7 and 8.
For Best Performance
For the best possible performance, install eight identical DIMMs in slots 1–8. If you
don’t have eight matching DIMMs, install four identical DIMMs in slots 1–4 and a
second set of four identical DIMMs in slots 5–8.
Always fill slots 1–4 before you install DIMMs in slots 5–8. After you fill slots 1–4, add a
full set of four DIMMs in slots 5–8 instead of just a pair in slots 5 and 6.
