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

identical sets within a channel, will lead to memory errors.
Figure 14
shows a logical view of DIMMs and Channels.
