Intel® Server System M50CYP1UR Family System Integration and Service Guide

•
Memory slots associated with a given processor are unavailable if the corresponding processor
socket is not populated.
•
Processor sockets are self-contained and autonomous. However, all memory subsystem support
(such as memory RAS and error management) in the BIOS Setup are applied commonly for each
installed processor.
•
For best system performance, memory must be installed in all eight channels for each installed
processor.
•
For best system performance in dual processor configurations, installed DDR4 DIMM type and
population for DDR4 DIMMs configured to CPU 1 must match DDR4 DIMM type and population
configured to CPU 0.
C.2 Intel® Optane
™
Persistent Memory 200 Series Module Rules
All operating modes:
•
Only Intel® Optane
™
persistent memory 200 series modules are supported.
•
Intel Optane persistent memory 200 series modules of different capacities cannot be mixed within or
across processor sockets.
•
Memory slots supported by the Integrated Memory Controller 0 (IMC 0) (memory channels A and B)
of a given processor must be populated before memory slots on other IMCs.
•
For multiple DIMMs per channel:
o
Only one Intel® Optane
™
persistent memory 200 series module is supported per memory channel.
o
Intel® Optane
™
persistent memory 200 series modules are supported in either DIMM slot when
mixed with LRDIMM or 3DS-LRDIMM.
o
Intel® Optane
™
persistent memory 200 series modules are only supported in DIMM slot 2 (black
slot) when mixed with RDIMM or 3DS-RDIMM.
•
No sup
port for SDRAM SRx8 DIMM that is populated within the same channel as the Intel® Optane™
persistent memory 200 series module in any operating mode.
•
Ensure the same DDR4 DIMM type and capacity is used for each DDR4 + Intel® Optane™ persistent
memory 200 series module combination.
Memory mode:
•
Populate each memory channel with at least one DDR4 DIMM to maximize bandwidth.
•
Intel® Optane™ persistent memory 200 series modules must be populated symmetrically
for each
installed processor (corresponding slots populated on either side of each processor).
App Direct mode:
•
Minimum of one DDR4 DIMM per IMC (IMC 0, IMC 1, IMC 2 and IMC 3) for each installed processor.
•
Minimum of one Intel® Optane™ persistent memory 200 series module for the board.
•
Intel® Optane™ persistent memory 200 series modules must be populated symmetrically
for each
installed processor (corresponding slots populated on either side of each processor).
