2.0Interfaces

2.1System Memory Interface

•Two channels of DDR3/DDR3L Unbuffered Dual In-Line Memory Modules (UDIMM) or DDR3/DDR3L Unbuffered Small Outline Dual In-Line Memory Modules (SO- DIMM) with a maximum of two DIMMs per channel.

•Single-channel and dual-channel memory organization modes

•Data burst length of eight for all memory organization modes

•Memory data transfer rates of 1333 MT/s and 1600 MT/s

•64-bit wide channels

•DDR3/DDR3L I/O Voltage of 1.5 V for Desktop

•The type of the DIMM modules supported by the processor is dependent on the PCH SKU in the target platform:

—Desktop PCH platforms support non-ECC UDIMMs only

—All In One platforms (AIO) support SO-DIMMs

•Theoretical maximum memory bandwidth of:

—21.3 GB/s in dual-channel mode assuming 1333 MT/s

—25.6 GB/s in dual-channel mode assuming 1600 MT/s

•1Gb, 2Gb, and 4Gb DDR3/DDR3L DRAM device technologies are supported

—Using 4Gb DRAM device technologies, the largest system memory capacity possible is 32 GB, assuming Dual Channel Mode with four x8 dual ranked DIMM memory configuration

•Up to 64 simultaneous open pages, 32 per channel (assuming 8 ranks of 8 bank devices)

•Processor on-die VREF generation for DDR DQ Read and Write as well as

CMD/ADD

•Command launch modes of 1n/2n

•On-Die Termination (ODT)

•Asynchronous ODT

•Intel Fast Memory Access (Intel FMA):

—Just-in-Time Command Scheduling

—Command Overlap

—Out-of-Order Scheduling
