IBM System x3950 X6

The following table shows the processor options. Each option includes the processor installed in a
Compute Book.
Note
s:
Compute Books with E7-4800 v2 processors are supported only in a four-socket x3850 X6 server and
cannot be used in an x3950 X6 server.
For models with E7-8850 v2 processors, eXFlash DIMMs are supported but currently can only be
ordered as options and not part of a configure-to-order configuration.
The table also shows the maximum memory bus speed each processor supports plus which server
models have each processor standard. If there is no corresponding
where-used
model for a particular
processor, this processor is only available through CTO.

† The processors support two memory modes, RAS mode (also known as lockstep mode) and Performance mode
(also known as independent mode). In Performance mode, the SMI2 link operates at twice the memory bus speed
shown.
