2.2 POWER7+ processor modules
The Power 720 and Power 740 server chassis house POWER7+ 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 POWER7+ processors in the system must be the same frequency and have
the same number of processor cores. POWER7+ processor types cannot be mixed within
a system.
