2.2 processor modules
The Power 720 and Power 740 server chassis house processor single chip
modules (SCMs). Each SCM can access eight DDR3 memory DIMM slots.
The Power 720 server houses one processor module offering 4-core 3.6 GHz, 6-core
3.6 GHz, or 8-core 3.6 GHz configurations.
The Power 740 server houses one or two processor modules. Each processor module can be
a 6-core 4.2 GHz or an 8-core 3.6 GHz or 4.2 GHz. All of the installed processors must be
activated, unless they are factory deconfigured using FC 2319.
2.2.1 Modules and cards
Figure 2-7 shows the system planar highlighting the POWER7 processor modules and the
memory riser cards.

Note: All processors in the system must be the same frequency and have
the same number of processor cores. processor types cannot be mixed within
a system.
