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:
— ECC and non-ECC un-buffered DIMMs. No support for mixed ECC and non-ECC
DIMM configurations.
DDR3 Data Transfer Rates:
— 800 MT/s (PC3-6400), and 1066 MT/s (PC3-8500)
• DDR3 DIMM Modules:
— Raw Card A – single rank x8 unbuffered non-ECC
— Raw Card B – dual rank x8 unbuffered non-ECC
— Raw Card C – single rank x16 unbuffered non-ECC
— Raw Card D – single rank x8 unbuffered ECC
— Raw Card E – dual rank x8 unbuffered ECC
— Raw Card F - dual rank x16 unbuffered non-ECC
• DDR3 DRAM Device Technology:
— Standard 1-Gb, and 2-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.
