This chapter describes the interfaces supported by the processor. 

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 

 for supported memory configuration details.

It supports a maximum of two DDR3 DIMMs per-channel; thus, allowing up to four 
device ranks per-channel.
