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.
Virtual Single Channel (VSC)
If both channels are populated with different memory configurations,
the MCH defaults to Virtual Single Channel.
Dual Channel (DC)
Dual channel provides better system performance because it doubles
the data transfer rate.
Dynamic Mode Addressing
This mode minimizes the overhead of opening/closing pages in
memory banks allowing for row switching to be done less often.
• DIMMs are on the same channel.
• DIMMs in a channel can be identical or
completely different.
• Not all slots need to be populated.
• DIMMs of different memory configura-
tions are on different channels.
• Odd number of slots can be popu-
lated.
• DIMMs of the same memory configu-
ration are on different channels.
• In single channel, requires even
number or rows (side of the DIMM)
populated. This mode can be enabled
with 1 SS, 2 SS or 2 DS.
• In VSC mode, both channels must have
identical row structure.
