Memory Configuration PRIMERGY RX200 S8
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
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.
Capacity Configuration UDIMM RDIMM LRDIMM Notes
Max. Memory per CPU 8/12 Modules / CPU with one CPU
Max. Memory per System 16/24 Modules / System if second CPU is configured
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
CPU with 1600MHz DDR3 Bus
CPU with 1333MHz DDR3 Bus
2R - Dual Rank
8R - Eight Rank
1DPC = 1 DIMM per Channel
2DPC = 2 DIMM per Channel
3DPC = 3 DIMM per Channel
- The memory sockets on the systemboard offer a color coding:
- 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
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.
