Dual-Channel Symmetric mode, also known as interleaved mode, provides maximum 
performance on real world applications. Addresses are ping-ponged between the 
channels after each cache line (64-byte boundary). If there are two requests, and the 
second request is to an address on the opposite channel from the first, that request can 
be sent before data from the first request has returned. If two consecutive cache lines 
are requested, both may be retrieved simultaneously since they are ensured to be on 
opposite channels. Use Dual-Channel Symmetric mode when both Channel A and 
Channel B DIMM connectors are populated in any order, with the total amount of 
memory in each channel being the same.

When both channels are populated with the same memory capacity and the boundary 
between the dual channel zone and the single channel zone is the top of memory, IMC 
operates completely in Dual-Channel Symmetric mode. 

The DRAM device technology and width may vary from one channel to the other. 

In all modes, the frequency of system memory is the lowest frequency of all memory 
modules placed in the system, as determined through the SPD registers on the 
memory modules. The system memory controller supports only one DIMM connector 
per channel. The usage of DIMM modules with different latencies is allowed. For dual-
channel modes, both channels must have an DIMM connector populated. For single-
channel mode, only a single-channel can have a DIMM connector populated.
