1-5 Installing an Expansion Card

Read the following guidelines before you begin to install an expansion card:

• Make sure the motherboard supports the expansion card. Carefully read the manual that came

with your expansion card.

• Always turn off the computer and unplug the power cord from the power outlet before installing an

expansion card to prevent hardware damage.

Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.

1. Dual Channel mode cannot be enabled if only one memory module is installed.

2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of

the same capacity, brand, speed, and chips be used for optimum performance.
