Functional Description
populate or not to populate any rank on either channel, including either degenerate
single channel case.
Flex Mode
This mode provides the best performance flexibility. The lowest DRAM memory is
mapped to two channel operation and the top most , if any, DRAM memory is mapped
to single channel operation. The drawbacks of Flex mode are that the system designer
must populate both channels of memory to get the benefits of flex mode, and there
will be multiple zones of Dual/single channel operation across the entire of DRAM
memory.
