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 / DDR3L 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.
Note: The processor supports only JEDEC approved memory modules and devices.
Note: The IMC supports a maximum of two DIMMs per channel; thus, allowing up to four
device ranks per channel.
Note: The supported memory interface frequencies and number of DIMMs per channel are
SKU dependent.
Note: There is no support for DDR3L DIMMs/DRAMS running at 1.35 V.
• DDR3 / DDR3L at 1.5 V Data Transfer Rates
— 1333 MT/s (PC3-10600), 1600 MT/s (PC3-12800)
• DDR3 / DDR3L at 1.5 V 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 platform DDR3/DDR3L at 1.5 V UDIMM 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
Note: The processor supports memory configurations that mix DDR3 DIMMs / DRAMs with
DDR3L DIMMs / DRAMs running at 1.5
V.
