PT800-AL supports single channel memory interface. Data will be
accessed in chunks of 64 bits from the memory channels.
PT880-AL suppor ts dual channel memory interface. The three
DDR DIMM sockets are divided into 2 channels:
Channel A - DDR 1 and DDR 2
Channel B - DDR 3
Data will be accessed in chunks of 128 bits from the memory
channels. Dual channel provides better system performance be-
cause it doubles the data transfer rate.
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.
DIMMs of the same memory configu-
ration are on different channels.
