Replacing or adding memory
The Synchronous Dynamic Random Access Memory (SDRAM) Dual Inline
Memory Modules (DIMMs) supported by your system board conform to the
following standards:
■
64 MB, 128 MB, 256 MB, and 512 MB ECC DIMMs.
■
PC133-compliant, registered, parity, ECC SDRAM.
Memory is installed in four banks (slots) on the system board. When you are
selecting and installing DIMMs, keep the following in mind:
■
Registered DIMMs should not be combined with unbuffered DIMMs.
■
Memory must be installed in reverse order, from right to left (from
bank 3, through bank 0).
■
No jumper settings are required for the memory size or type because the
BIOS automatically detects this information.
■
2 GB maximum system memory.
To replace DIMMs:
1 Turn off the system and disconnect the power cord, modem cord (if
installed), and all external peripheral devices.
2 Observe all safety and static electricity precautions. (See “Preventing static
electricity discharge” on page 22.)
3 Remove the bezel. (See “Removing the bezel” on page 25.)
4 Remove the left side cover panel. (See “Removing the side cover panel”
on page 26.)
