Memory
- There are 8 memory slots per CPU for max.
128GB RDIMM (8x 16GB dual rank)
32GB UDIMM (8x 4GB)
=> max. 256GB per node
- The memory area is divided into 4 channels per CPU with 2 slots per channel
- Slot 1 of each channel belongs to memory bank 1, the slot 2 belongs to memory bank 2
Registered, LR DIMMs and unbuffered memory modules can be selected
No mix of registered, load reduced and unbuffered modules allowed.
Memory can be operated at 1.5V or 1.35V, even if the modules are of low voltage type.
In a 2 DIMMs per channel configuration, following frequencies are supported:
- 1.5V - 1600MHz max (depending on CPU, special memory modules)
- 1.35V - 1333MHz max (depending on CPU)
SDDC (Chipkill) is supported for registered / load reduced memory modules only (not unbuffered)
"Independent Channel Mode" is following configuration possible
- Each slot can optionally be equipped with any registered or load reduced or unbuffered DDR3 modules:
No mix of registered, load reduced and unbuffered modules allowed.
"Performance Mode" configuration
- In this configuration, the memory module population ex factory is spread across all channels.
The BIOS is set to the max. performance for memory.
Minimum configuration is: 4x identical modules per CPU
"Rank Sparing Mode" configuration
The Spare Rank is held in reserve and is not available as system memory
For the effective memory capacity, please refer to the spreadsheet below.
The BIOS is set to the rank sparing setting.
Minimum configuration is: 2x 1R, 2x 2R or 1x4R DDR3 module per channel
This mode is not supported by unbuffered memory modules
"Mirrored Channel Mode" is following configuration possible
- Each memory bank can optionally be equipped with 4x registered or load reduced or unbuffered DDR3 modules
In each memory bank channel A and B / C and D of CPU 1 or channel E and F / G and H of CPU 2 have to be
equipped with identical modules for mirrored channel mode.
In channel B / D is always the mirrored memory of channel A / B of CPU 1
In channel F / H is always the mirrored memory of channel E / G of CPU 2
Minimum configuration is: 4x identical modules
This mode is not supported by unbuffered memory modules

Performance Mode Installation
Number of memory modules is always 4 / CPU, so all channels are populated and the max. memory performance can be achieved.
Four identical memory modules will be equipped in one memory bank to achieve highest memory performance. All four modules are active
and full capacity can be used.
1x per CPU Multiple of 4 identical modules to be configured per CPU
S26361-F3694-E10
Independent Mode
Independent Channel Mode allows all channels to be populated in any order. No specific Memory RAS features are defined
Requires min 1 memory Module per CPU
S26361-F3694-E1 Rank Sparing Mode Installation
BIOS Setup factory preinstalled to this mode. One Rank is spare of other ranks on the same channel. Spare Rank is not shown in System Memory.
For effective capacity within a channel, please have a look below.
Supported for RDIMM only.
Requires min 2x 1R/2R or 1x 4R modules per CPU
S26361-F3694-E3 Mirrored Channel Mode Installation as soon as available
BIOS Setup factory preinstalled to this mode. Four identical memory modules are always equipped in one memory bank to use the
Mirrored channel Mode. Only two modules contain active data, the remain two modules contain mirrored data
Supported for RDIMM only.

Max. DDR3 memory speed depends on the memory
configuration. (No of mem modules per channel)
as well as on the CPU type.
The memory channel with the lowest speed defines
the speed of all CPU channels in the system, also for
the channels of the second CPU if configured.
For real memory speed (depending on memory type /
population), please check the spreadsheet "Memory
speed" below
