Cisco UCS B440 High Performance Blade Server Installation and Service Note

OL-22475-01

Memory and Performance

Note

This server does not support odd numbers of DIMMs in a channel, or a configuration of 6 DIMMs per
CPU. These are the only three supported DIMM configurations. The DIMMs are sold in matched pairs
which must be installed in the pairs shown in

Table 8

. Mixing pairs , even otherwise identical sets, within

a CPU will lead to memory errors.

Figure 15

shows a logical view of the channels.

Figure 15

Logical Representation of Channels

DIMMs can be used in the High-performance blade server using the slot pairs described in

Table 8

Memory Performance

When configuring your server, consider the following.

•

DIMMs within the blade server can be of a different size, but mixing 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. If two CPUs are used, both must be of
the same type.
