Lenovo System x3850 X6 Product Manual page 14

One processor
A total of 24 DIMM slots, 12 on each side of the book
Two hot-swap dual-motor fans that are mounted on the front of the book
The x3850 X6 supports two or four Compute Books. Three Compute Books are not supported. A
configuration of one Compute Book is only supported in standard models 6241-A4x and 6241-D5x.
Each Compute Book is installed in the front of the server, as shown in the following figure.
Figure 4. Compute Book
The following table shows the processor options, grouped as follows:
E7-4800 v4 processors in Compute Books with TruDDR4 support
E7-8800 v4 processors in Compute Books with TruDDR4 support
E7-4800 v3 processors in Compute Books with DDR3 support
E7-8800 v3 processors in Compute Books with DDR3 support
E7-4800 v3 processors in Compute Books with TruDDR4 support
E7-8800 v3 processors in Compute Books with TruDDR4 support
Each option includes the processor installed in a Compute Book. Compute Books with one of the E7-4800
family of processors are supported only in a four-socket x3850 X6 server and cannot be used in an x3950
X6 server. All Compute Books installed in a server must be identical.
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.
