Hardware Installation

The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) from the memory
channels.
Dual Channel (DC)
Data will be accessed in chunks of 128 bits from the memory
channels. Dual channel provides better system performance because
it doubles the data transfer rate.

The table below shows the DIMM sockets that must be populated
with DIMMs for single or dual channel interface. We strongly
recommend that you strictly follow the memory configurations below.
Installing DDR2 DIMMs other than the recommended configurations
may cause system boot failure.

• DIMMs are on the same channel.
• DIMMs in a channel can be identical or
completely different. However, we highly
recommend using identical DIMMs.
• Not all slots need to be populated.
• DIMMs of the same memory configura-
tion are on different channels.
