 DIMM slots on any memory channel must be filled following the “farthest fill first” rule.
 A maximum of 8 ranks can be installed on any one channel, counting all ranks in each
DIMM on the channel.
 DIMM types (UDIMM, RDIMM, LRDIMM) must not be mixed within or across processor
sockets.
 Mixing ECC with non-ECC DIMMs (UDIMMs) is not supported within or across
processor sockets.
 Mixing Low Voltage (1.35V) DIMMs with Standard Voltage (1.5V) DIMMs is not
supported within or across processor sockets.
 Mixing DIMMs of different frequencies and latencies is not supported within or across
processor sockets.
 LRDIMM Rank Multiplication Mode and Direct Map Mode must not be mixed within or
across processor sockets.
 Only ECC UDIMMs support Low Voltage 1.35V operation.
 QR RDIMMs may only be installed in DIMM Slot 1 or 2 on a channel.
 2 DPC QR Low Voltage RDIMMs are not supported.
 In order to install 3 QR LRDIMMs on the same channel, they must be operated with
Rank Multiplication as RM = 2.
 RAS Modes Lockstep, Rank Sparing, and Mirroring are mutually exclusive in this BIOS.
Only one operating mode may be selected, and it will be applied to the entire system.
 If a RAS Mode has been configured, and the memory population will not support it
during boot, the system will fall back to Independent Channel Mode and log and display
errors
 Rank Sparing Mode is only possible when all channels that are populated with memory
meet the requirement of having at least 2 SR or DR DIMM installed, or at least one QR
DIMM installed, on each populated channel.
 Lockstep or Mirroring Modes require that for any channel pair that is populated with
memory, the memory population on both channels of the pair must be identically sized.
4.2.2.3 Publishing System Memory
The BIOS displays the “Total Memory” of the system during POST if Quite Boot is disabled in
the BIOS setup. This is the total size of memory discovered by the BIOS during POST, and is
the sum of the individual sizes of installed DDR3 DIMMs in the system.
The BIOS displays the “Effective Memory” of the system in the BIOS setup. The term Effective
Memory refers to the total size of all DDR3 DIMMs that are active (not disabled) and not used
as redundant units.
The BIOS provides the total memory of the system in the main page of the BIOS setup. This
total is the same as the amount described by the first bullet above.
If Quite Boot is disabled, the BIOS displays the total system memory on the diagnostic screen at
the end of POST. This total is the same as the amount described by the first bullet above.
4.2.2.4 RAS Features
The server board supports the following memory RAS modes:
