DIMM_ERROR_OVERFLOW_STATUS
This 12-bit field is the per dimm error overflow status bits. The organization is
as follows:
If there are three or more DIMMS on the channel:
Bit 0 = DIMM 0 Channel 0
Bit 1 = DIMM 1 Channel 0
Bit 2 = DIMM 2 Channel 0
Bit 3 = DIMM 3 Channel 0
Bit 4 = DIMM 0 Channel 1
Bit 5 = DIMM 1 Channel 1
Bit 6 = DIMM 2 Channel 1
Bit 7 = DIMM 3 Channel 1
Bit 8 = DIMM 0 Channel 2
Bit 9 = DIMM 1 Channel 2
Bit 10 = DIMM 2 Channel 2
Bit 11 = DIMM 3 Channel 2
If there are one or two DIMMS on the channel:
Bit 0 = DIMM 0, Ranks 0 and 1, Channel 0
Bit 1 = DIMM 0, Ranks 2 and 3, Channel 0
Bit 2 = DIMM 1, Ranks 0 and 1, Channel 0
Bit 3 = DIMM 1, Ranks 2 and 3, Channel 0
Bit 4 = DIMM 0, Ranks 0 and 1, Channel 1
Bit 5 = DIMM 0, Ranks 2 and 3, Channel 1
Bit 6 = DIMM 1, Ranks 0 and 1, Channel 1
Bit 7 = DIMM 1, Ranks 2 and 3, Channel 1
Bit 8 = DIMM 0, Ranks 0 and 1, Channel 2
Bit 9 = DIMM 0, Ranks 2 and 3, Channel 2
Bit 10 = DIMM 1, Ranks 0 and 1, Channel 2
Bit 11 = DIMM 1, Ranks 2 and 3, Channel 2
