2.4.3Memory sparing technology

The Intel® Seab���urg �������chipset ��������supports ���the ������memory �������sparing �����������technology. �����Refer ��to ���the below sections:

Memory Sparing :

At configuration 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.
