Adding or replacing memory modules

The computer has two memory module slots (or 4 memory module slots if there are quad core processors). The capacity of the computer can be upgraded by adding a memory module to the vacant expansion memory module slot or by upgrading the existing memory module in the memory module slot.

WARNING! To reduce the risk of electric shock and damage to the equipment, unplug the power cord and remove all batteries before installing a memory module.

CAUTION: Electrostatic discharge (ESD) can damage electronic components. Before beginning any procedure, ensure that you are discharged of static electricity by touching a grounded metal object.

NOTE: Computers with dual core processors have 2 slots. Computers with quad core processors have 4 slots.

NOTE: To use a dual-channel configuration when adding a second memory module, be sure that both memory modules are identical.
