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 dependent on the Intel 5 Series Chipset SKU in
the target platform:
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.
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.
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.
four device ranks per channel.
