1.2.1.2
Mobile Intel Arrandale system memory support
The Integrated Memory Controller (IMC) supports DDR3 protocols with two, independent, 64-bit wide channels
each accessing one SO-DIMM. It supports a maximum of one, unbuffered non-ECC DDR3 SO-DIMM per-
channel thus allowing up to two device ranks per-channel. DDR3 Data Transfer Rates: — 800 MT/s (PC3-6400),
and 1066 MT/s (PC3-8500)
¾
DDR3 SO-DIMM Modules:
— Raw Card A – double-sided x16 unbuffered non-ECC
— Raw Card B – single-sided x8 unbuffered non-ECC
— Raw Card C – single-sided x16 unbuffered non-ECC
— Raw Card D – double-sided x8 (stacked) unbuffered non-ECC
— Raw Card F – double-sided x8 (planar) 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.
