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 dependent on the Intel 5 Series Chipset SKU in 
the target platform:

• Desktop Intel 5 series Chipset platforms support non-ECC unbuffered DIMMs only 

and do not support any memory configuration that mixes non-ECC with ECC 
unbuffered DIMMs.

• Server and Workstation Intel 3400 Series Chipset platforms support ECC 

unbuffered DIMMs. Workstation Intel 3400 Series Chipset platforms also support 
non-ECC unbuffered DIMMs. Workstation Intel 3400 Series Chipset platforms do 
not support any memory configuration that mixes non-ECC with ECC unbuffered 
DIMMs.

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