1.2 Interfaces
1.2.1 System Memory Support
• Two channels of unbuffered DDR3 memory with a maximum of two UDIMMs or SO-
DIMMs (for AIO) per channel
• Single-channel and dual-channel memory organization modes
• Data burst length of eight for all memory organization modes
• Memory DDR3 data transfer rates of 1066 MT/s and 1333 MT/s
• 64-bit wide channels
• DDR3 I/O Voltage of 1.5 V
• The type of memory supported by the processor is dependent on the PCH SKU in
the target platform
— Desktop PCH platforms support non-ECC un-buffered DIMMs only
— All In One platforms (AIO) support SO-DIMMs
• Maximum memory bandwidth of 10.6 GB/s in single-channel mode or 21 GB/s in
dual-channel mode assuming DDR3 1333 MT/s
• 1Gb, 2Gb, and 4Gb DDR3 DRAM technologies are supported
— Using 4Gb device technologies, the largest memory capacity possible is 32 GB,
assuming Dual Channel Mode with four x8 dual ranked unbuffered DIMM
memory configuration.
