Figure 7-39 MAX5 Memory Scaling option in System x3690 X5 UEFI
The MAX5 Memory Scaling setting provides two options to determine how the system will
present the memory capacity in the MAX5 unit to the running OS:
Non-Pooled
The default option splits the memory in the MAX5 and assigns part of it to each of the
installed processors.
Pooled
This option presents the additional memory in the MAX5 as a separate pool of memory
without its being assigned to any particular processor.

7.8.2 Operating system-specific settings

Determining what memory scaling option to use depends on the installed OS. The x3690 X5
only supports the x64 (AMD64/EM64T) version of the supported OSs in order to take
advantage of the server's memory expansion capability.
Windows Server setting
The following Windows Server versions are supported:
Windows Server 2008 R2
Windows Server 2008 x64 Edition
When running Windows Server on the memory-expanded x3690 X5, set the MAX5 Memory
Scaling option to Non-Pooled.
