below sections:

Memory Sparing :

At conguration time, a DIMM rank is set aside to replace a defective DIMM rank.

When the error rate for a failing DIMM rank reaches a pre-determined threshold,

the memory sparing function will issue an interrupt and initiate a spare copy. At the

completion of the copy, the failing DIMM rank is disabled and the “spared” DIMM

rank will be used in its place.

• The DIMM rank with the largest size will be assigned as spare rank. Data

can only be copied from a smaller sized rank to a larger sized one.

• A DIMM can contain only one or two ranks. To support sparing function, a

DIMM channel should contain at least two ranks.

• When sparing function is enabled, the usable memory size will reduce then

size of the spare ranks.
