Processor/Memory Subsystem

3.1Introduction

This systems provide an LGA 1155 (H2) socket supporting an Intel Celeron, Pentium Dual-Core, Core i3, Core i5, or Core i7 processor. These processors include an integrated dual-channel DDR3 memory controller (Figure 3-1) and support PC3-8500 and PC3-10600 memory modules. This chapter describes the processor/memory subsystem.
