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
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
— Raw Card A - Single Ranked x8 unbuffered non-ECC
— Raw Card B - Dual Ranked x8 unbuffered non-ECC
— Raw Card C - Single Ranked x16 unbuffered non-ECC
