Install a Memory Riser Card
Supported DIMMs and DIMM Population Rules
This section describes the supported DIMM configuration and population rules for memory
risers in the system. Use only Oracle supported DIMMs in the system.
Supported configurations:
■
Minimum supported configuration:
■
Two or Four-CPU system:
Two DDR3 (Double Data Rate 3) 16 GB low voltage RDIMMs (Registered Dual In-
Line Memory Modules) installed in each memory riser, slots D0 and D3.
■
Maximum supported configuration:
■
Two-CPU system:
Up to 48 DDR3 low voltage RDIMMs
or LRDIMMs (Load Reduced Dual In-Line
Memory Modules) are supported.
■
Four-CPU system:
Up to 96 DDR3 low voltage RDIMMs
or LRDIMMs are supported.
Supported DIMM types and sizes available from Oracle:
Note - DIMM system performance speed maximum is 1600 MHz in one or two DIMM per
channel configuration, or up to 1333 MHz in three DIMM per channel configuration (even if
the DIMMs are rated higher).
DIMM Size Type Organization
16 GB DDR3-1600 LV RDIMM Dual-rank by-4 (2Rx4)
32 GB DDR3-1600 LV LRDIMM Quad-rank by-4 (4Rx4)
Population rules:
■
Only one type and size DIMM is supported in the system at any time. Mixing DIMMs of
different size or technology (such as RDIMMs and LRDIMMs) is not supported.
■
When upgrading to a different size DIMM, replace all DIMMs in the system to match the
new capacity.
■
All memory riser cards must be populated identically.
■
Install DIMMs in the following sequence for each memory riser card (refer to the
illustrations that follow for additional details):
