CONFIGURING the SERVER

(2) 4-CPU Configuration

32 DIMMs capacity total

■

Select two or four DIMM kits ( 4 or 8 DIMMs) per CPU. The DIMMs for each CPU will be placed

■

by the factory as shown in

per CPU

Notes . . .

1. Two UCS-MR-2X041RX-C, UCS-MR-2X082RX-C, UCS-MR-2X164RX-D, or UCS-MR-2X324RX-C DIMM kits per CPU

2. Four UCS-MR-2X041RX-C, UCS-MR-2X082RX-C, UCS-MR-2X164RX-D, or UCS-MR-2X324RX-C DIMM kits per CPU, or

one of these combinations: (1) Two UCS-MR-2X082RX-C and two UCS-MR-2X164RX-D DIMM kits per CPU, or (2)

two UCS-MR-2X082RX-C and two UCS-MR-2X324RX-C DIMM kits per CPU, or (3) two UCS-MR-2X164RX-D and two

UCS-MR-2X324RX-C DIMM kits per CPU.

Caveats

The only supported DIMM configurations are shown in

■

DIMMs are sold in matched pairs, which must be installed in pairs shown in the tables.

Switching out one of the DIMMs within the matched pair will lead to memory errors.

The B440 M2 server needs at least two DIMM pairs installed for each CPU for optimal

■

performance

DIMMs sold as kits are matched pairs and must remain together when installed in a particular

■

pair of same-colored (blue, white, yellow, or black) pairs of slots.

The DIMMs installed in slots for an absent CPU are not recognized.

■

Memory DIMMs should be installed evenly across the installed CPUs, though it is not a

■

requirement.

Mixing DIMM speeds will cause the faster DIMMs to run at the speed of the slower DIMMs.

■

Your selected CPU(s) can have some affect on performance. The CPUs must be of the same

■

type.
