Interfaces
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 protocols with two
independent, 64-bit wide channels each accessing one DIMM. It supports a maximum
of one unbuffered non-ECC DDR3 DIMM per-channel; thus, allowing up to two device
ranks per-channel.
• DDR3 Data Transfer Rates
— 1066 MT/s (PC3-8500), 1333 MT/s (PC3-10600), 1600 MT/s (PC-12800)
• DDR3 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
• DDR3 DRAM Device Technology
Standard 1-Gb, 2-Gb, and 4-Gb technologies and addressing are supported for x16 and
x8 devices. There is no support for memory modules with different technologies or
capacities on opposite sides of the same memory module. If one side of a memory
module is populated, the other side is either identical or empty.
Notes:
1.
System memory configurations are based on availability and are subject to change.
2.
Interface does not support ULV/LV memory modulates or ULV/LV DIMMs.
