This chapter describes the interfaces supported by the processor.
2.1 System Memory Interface
2.1.1 System Memory Technology Supported
The Integrated Memory Controller (IMC) supports DDR3 protocols with two
independent, 64-bit wide channels each accessing one or two DIMMs. The type of
memory supported by the processor is dependant on the PCH SKU in the target
platform. Refer to Chapter 1 for supported memory configuration details.
It supports a maximum of two DDR3 DIMMs per-channel; thus, allowing up to four
device ranks per-channel.
• DDR3 Data Transfer Rates
— 1066 MT/s (PC3-8500), 1333 MT/s (PC3-10600)
• DDR3 SO-DIMM Modules
— Raw Card A – Dual Ranked x16 unbuffered non-ECC
— Raw Card B – Single Ranked x8 unbuffered non-ECC
— Raw Card C – Single Ranked x16 unbuffered non-ECC
— Raw Card F – Dual Ranked x8 (planar) unbuffered non-ECC
• Desktop PCH platform DDR3 DIMM Modules
