4.7.1
Independent Channel Mode
In independent mode, all three channels are operating independently. The ECC code appears
in each independent channel. Failure of the DRAM can be corrected. The correction capabilities
in independent mode are:
Correction of any x4 DRAM device failure.
Detection of 99.986% of all single bit failures that occur in addition to an x4 DRAM failure.
Detection of any 2-bit uncorrectable errors.
4.7.2
Spare Channel Mode
In Spare Channel Mode, Channel 0 and 1 are active channels and Channel 2 is the spare of the
other two channels. The spare channel is held in reserve and is not available as system memory.
The spare channel must have identical population to the channel being copied from. This
means that all three channels must have identical population with regards to size and
organization. DIMM slot populations. The Memory Controller will maintain correctable ECC
error counters for each DIMM in the system that can either trigger an SMI event or be
periodically polled by software to determine whether a high error rate is happening. SMI
software can then configure the Integrated Memory Controller to copy contents from one
channel to another.
4.7.3
Mirrored Channel Mode
The Integrated Memory Controller supports mirroring across channels. DIMM organization in
each slot of one channel must be identical to the DIMM in the corresponding slot of the other
channel. When mirroring is enabled, the memory image in Channel 0 is maintained the same
as Channel 1. DIMMs in Channel 2 are not used.
Uncorrectable errors are logged and signaled as correctable, but change the channel state to
"Disabled", and the working partner to Redundancy Loss.
