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

Mode Configuration Application

SDDC (chipkill) support any no no yes detect multi-bit errors

Independant Channel 1, 2 or 3 Modules per Bank yes yes yes offers max. flexibility, upgradeability, capacity

Mode

use UDIMM modules for lowest cost

Mirrored Channel Mode *) 4 identical Modules / Bank no no yes offers maximum security

Performance Mode 4 identical Modules / Bank yes yes yes offers maximum performance and capacity

Rank Sparing Mode *) min. 2 Ranks / Channel no no yes

balances security and capacity

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

Max. Memory per System 16/24 Modules / System 64GB 384GB 768GB if second CPU is configured

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

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 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

Bank III 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.
