Memory Configuration PRIMERGY CX272 S1
Each CPU offers 8 Slots for DDR3 Memory Modules organised in 2 Banks and 4 Channels.
Depending on the amount of memory configured you can decide between 4 basic modes of operation (see explanation below).
There are 3 different kinds of DDR3 Memory Modules available: UDIMM / RDIMM
UDIMM / RDIMM offer different functionality. Mix of UDIMM / RDIMM is not alloved.
If 1.5V and 1.35V DIMMs are mixed, the DIMMs will run at 1.5V

Memory-Speed:
Max. DDR3 memory speed depends on the memory configuration on one memory channel and the speed of the CPU
The memory channel with the lowest speed defines the speed of all CPU channels in the system
Mem. Speed provided

Voltage setting (BIOS)
CPU with 1600MHz DDR3 Bus
CPU with 1333MHz DDR3 Bus

1R - Single Rank
2R - Dual Rank
4R - Quad Rank
1DPC = 1 DIMM per Channel
2DPC = 2 DIMM per Channel
3DPC = 3 DIMM per Channel
Configuration hints:
- The memory sockets on the systemboard offer a color coding:
Bank I
black sockets
Bank II
blue sockets
- A so called Bank consits of 1 memory module on every Channel available on one CPU (examples see below)
Bank I on CPU 1/2
up to 4 memory modules connected to Channel A - H on the 1st/2nd CPU
Bank II on CPU 1/2
up to 4 memory modules connected to Channel A - E on the 1st/2nd CPU
(can not be populated by UDIMM or 4R RDIMM memory modules)
- See below and next page for a detailed descriptions of the memory configuration supported.
