Memory Configuration PRIMERGY RX300 S7
Each CPU offers 12 Slots for DDR3 Memory Modules organised in 3 Banks and 4 Channels.
If you need more than 12 Slots you have to configure the 2nd CPU.
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 and LRDIMM
UDIMM / RDIMM / LRDIMM offer different functionality. Mix of UDIMM / RDIMM / LRDIMM is not alloved.
If 1.5V and 1.35V DIMMs are mixed, the DIMMs will run at 1.5V

Capacity
Min. Memory per CPU
Max. Memory per CPU
Max. Memory per System 16/24 Modules / System
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
by CPU
Voltage setting (BIOS)
CPU with 1600MHz DDR3 Bus
CPU with 1333MHz DDR3 Bus
CPU with 1066MHz 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
Bank III green 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
Bank II on CPU 1/2
Bank III on CPU 1/2
- See below and next page for a detailed descriptions of the memory configuration supported.
