Memory
You can upgrade your system memory to a maximum of 8 GB by installing 533MHz or, when available,
667MHz fully buffered DIMMs (FBDs) in dual sets of 256-MB, 512-MB, 1-GB, or 2-GB. The memory
sockets are located on the system board beneath the rotatable hard-drive carrier. See Figure 6-2.
NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them
separate from any new memory modules that you may have. Use only 533 MHz or, when available, 667 MHz FBDs.
