1.) In the "Independent Channel Mode" is following configuration possible
2.) "Performance Mode" configuration
Liquid Cooling supports Performance mode only
S26361-F3694-E10
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
1x per CPU
S26361-F3694-E2
BIOS Setup factory preinstalled for max. Performance, 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.
Multiple of 4 identical modules to be configured per CPU
E1
Memory
- There are 8 memory slots per CPU for max.
512GB LRDIMM (8x 64GB 4R)
256GB RDIMM (8x 32GB 2R)
CX25y0 M1:
=> max. 1.024GB for two CPU`s ( 512GB per CPU ), using LRDIMM
CX25y0 M2:
=> max. 1.024GB for two CPU`s ( 512GB per CPU ), using RDIMM or LRDIMM
- 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 and Load Reduced DIMMs can be selected
No mix of registered and load reduced modules is allowed.
Memory can be operated at 1.2V.
Depending on the CPU following memory speeds will be reached:
- 1DPC - 2133MHz max
within CX25y0 M1
- 2DPC - 1866MHz on RDIMM and 2133MHz on LR-DIMM
- 1DPC & 2DPC - 2400MHz max
SDDC (Chipkill) is supported for registered / load redueced x4 organized memory modules only
Channels can be populated in any order in Independent Channel Mode. All four
channels may be populated in any order and have no matching requirements. All
channels must run at the same interface frequency but individual channels may run at
different DIMM timings (RAS latency, CAS latency, and so forth)
No mix of registered, load reduced and unbuffered modules allowed.
No mix of registered and load reduced modules is allowed.
- 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 four identical modules per CPU
