Memory Configuration PRIMERGY BX920 S3

Each CPU offers 6 Slots for DDR3 Memory Modules organised in 2 Banks and 3 Channels.

If you need more than 6 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

Mode

SDDC (chipkill) support

Independant Channel

Mode

Mirrored Channel Mode *) 2 identical Modules / Bank

Performance Mode

Rank Sparing Mode *)

*) For the delivery ex works the system will be prepared with dedicated BIOS setting.

Capacity

Min. Memory per CPU

Max. Memory per CPU

Max. Memory per System 8/12 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

- See below and next page for a detailed descriptions of the memory configuration supported.
