Intel C602-J Chipset Overvew - Intel MFSYS25V2 Specification

Functional Architecture
3.4.4.4 Mirrored Channel Mode
In Mirrored Channel Mode, the memory contents are mirrored between Channel 0 and Channel 2
and also between Channel 1 and Channel 3. As a result of the mirroring, the total physical
memory available to the system is half of what is populated. Mirrored Channel Mode requires
that Channel 0 and Channel 2, and Channel 1 and Channel 3 must be populated identically with
regards to size and organization. DIMM slot populations within a channel do not have to be
identical but the same DIMM slot location across Channel 0 and Channel 2 and across Channel
1 and Channel 3 must be populated the same.
3.4.4.5 Lockstep Channel Mode
In Lockstep Channel Mode, each memory access is a 128-bit data access that spans Channel 0
and Channel 1, and Channel 2 and Channel 3. Lockstep Channel mode is the only RAS mode
that allows SDDC for x8 devices. Lockstep Channel Mode requires that Channel 0 and Channel
1, and Channel 2 and Channel 3 must be populated identically with regards to size and
organization. DIMM slot populations within a channel do not have to be identical but the same
DIMM slot location across Channel 0 and Channel 1 and across Channel 2 and Channel 3 must
be populated the same.
