a. Requires full processors in order to install and use all memory.
b. Requires that the memory mezzanine board is installed along with processor 2.
c. For the x3690 X5 and x3850 X5, additional backplanes might be needed to support these numbers of drives.
d. Depends on the model. See Table 3-2 on page 64 for the IBM System x3850 X5.

1.3.1 IBM System x3850 X5 and x3950 X5

The System x3850 X5 and the workload-optimized x3950 X5 are the logical successors to the
x3850 M2 and x3950 M2. The x3850 X5 and x3950 X5 both support up to four processors
and 1.024 TB (terabyte) of RAM in a single-node environment.
The x3850/x3950 X5 with the MAX5 memory expansion unit attached, as shown in
Figure 1-2, can add up to an additional 512 GB of RAM for a total of 1.5 TB of memory.

Two x3850/x3950 X5 servers can be connected for a single system image with a max of eight
processors and 2 TB of RAM.
Table 1-9 compares the number of processor sockets, cores, and memory capacity of the eX4
and eX5 systems.
