Memory Subsystem

3.2.1
Intel
QuickPath Memory Controller
®
®
®
The Intel
Xeon
Processor 5500 series and Intel
integrated memory controller, the Intel
memory controller supports DDR3 1333/1066/800 ECC registered DIMMs (RDIMMs) and ECC
unbuffered DIMMs (UDIMMs).
3.2.1.1
Intel
Compute Module MFS5520VI Supported Memory
®
®
The Intel
Compute Module MFS5520VI has 12 DIMM sockets and supports the following
memory features:
Six DDR3 memory channels (three per processor socket) with two DIMMs per channel,
thereby supporting up to 12 DIMMs with dual-processor sockets
DDR3 1333 MHz and DDR3 1066 MHz memory modules
Single–Rank (SR) and Dual–Rank (DR) ECC Registered (RDIMMs) or ECC Unbuffered
(UDIMMs) DDR3 memory modules
Quad–Rank (QR) ECC Registered (RDIMMs) DDR3 memory modules
Maximum memory capacity of 192 GB with two processors installed
Use of identical DIMMs in the compute module is recommended
The following configurations are not validated or supported with the Intel
MFS5520VI:
Mixing of RDIMMs and UDIMMs is not supported
Mixing memory type, size, speed and/or rank on this server board is not validated and is
not supported
Mixing memory vendors is not validated and is not supported on this server board
Non-ECC memory is not validated and is not supported in a server environment

Publishing Compute Module Memory

The BIOS displays the "Total Memory" of the compute module during POST if Display
Logo 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 compute module 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 compute module in the main page of the
BIOS setup. This total is the same as the amount described by the first bullet above.
If Display Logo 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.
