2. You cannot mix compute books that support E7-x8xx v2 series microprocessors and compute books
that support E7-x8xx v3 or v4 series microprocessors. All compute books in the server must support the
same series microprocessor.
The following are notes and information that you must consider when you install the compute book in the
server:
Note: The information and installation procedures in this documentation apply to both the 4-socket and the
8-socket configurations of the server, unless otherwise specified. Most of the illustrations in the
documentation show the 4-socket configuration of the server.
• The compute books should be installed from left to right (facing the front of the server).
• A minimum of two compute books must be installed in the 4-socket (x3850 X6) server.
• A minimum of four compute books must be installed in the 8-socket (x3950 X6) server.
• Each compute book must have a minimum of one microprocessor and one DIMM installed.
• The 4-socket (x3850 X6) server supports compute book configurations of two or four. These are the only
configurations supported. The following tables list the installation sequence for the supported compute
book configurations.

• The 8-socket (x3950 X6) server supports compute book configurations of four, six, or eight. These are the
only configurations supported. The following tables list the installation sequence for the supported
compute book configurations.
