48 IBM Power 770 and 780 (9117-MMD, 9179-MHD) Technical Overview and Introduction
2.2 POWER7+ processor card
IBM Power 770 and Power 780 servers are modular systems that are built with one to four
CEC enclosures. The processor and memory subsystem in each CEC enclosure is contained
on a single processor card. The processor card contains four processor sockets and 16 fully
buffered DDR3 memory DIMMs.
2.2.1 Overview
The IBM Power 770 processor card is populated with 3-core or 4-core POWER7+ processors.
This way enables a maximum system configuration of 64-cores, built from four CEC
enclosures.
The IBM Power 780 shares the same 4-socket processor card. The 780 processor cards are
populated with 4-core or 8-core POWER7+ processors, enabling a maximum system
configuration of 128 cores.
Figure 2-6 illustrates the major components of the 4-socket processor card.
