5 Processors

5.1 Overview

The AMD Opteron™ 6100, 6200, and 6300
server applications. These G34 processors feature up to sixteen-core processing to maximize
performance and performance/watt for data center infrastructures and highly dense deployments.
The G34 processor also features AMD Opteron micro-architecture and AMD64 architecture for
flexibility in 64-bit and 32-bit applications and operating
The G34 processor utilizes a 1944-contact Organic Land Grid Array (OLGA) package that plugs into a
surface-mount socket (Socket-G34). The PowerEdge R815 provides support for up to four G34
processors. See Table 7.
