2 DIMMs per channel 1333 MHz 1600 MHz 1600 MHz
3 DIMMs per channel No support No support 1066 MHz
* The maximum quantity that is supported is shown for two processors installed.
The following memory protection technologies are supported:
ECC

Chipkill (for x4-based memory DIMMs)

Memory mirroring

Memory rank sparing

If memory mirroring is used, DIMMs must be installed in pairs (minimum of one pair per each CPU), and
both DIMMs in a pair must be identical in type and size.
If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank
DIMMs must be installed per populated channel (the DIMMs do not need being identical). In rank sparing
mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank
varies depending on the DIMMs that are installed.
