The following table shows the maximum memory speeds that are achievable based on the installed
DIMMs and the number of DIMMs per channel. The table also shows the maximum memory capacity at
any speed that is supported by the DIMM and the maximum memory capacity at the rated DIMM speed. In
the table, cells that are highlighted with a gray background indicate when the specific combination of
DIMM voltage and number of DIMMs per channel still allows the DIMMs to operate at rated speed.
Note: The quantities and capacities are for one server (that is, half of the x222). The maximums for the
entire x222 (both servers) is double these numbers.

* The maximum quantity that is supported is shown for two installed processors. When one processor is installed,
the maximum quantity that is supported is half of that shown.
Install DIMM fillers in all empty DIMM sockets to ensure proper airflow.
The following memory protection technologies are supported:
ECC
Chipkill (for x4-based memory DIMMs; look for "x4" in the DIMM description)
Memory mirroring
Memory sparing
If memory mirroring is used, then the DIMMs must be installed in pairs (minimum of one pair per
processor), 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 to be 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.
