DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this configuration, 4 GB will
run as dual-channel and 1 GB will run as single-channel.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

IMPORTANT:
before adding or removing memory modules. Regardless of the power state, voltage is always supplied to
the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory
modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to
use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from
having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning
these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal
object. For more information, see the
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
