1.2 Interfaces
1.2.1 System Memory Support
• Two channels of DDR3 Unbuffered Dual In-Line Memory Modules (UDIMM) or DDR3
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 DDR3 data transfer rates of 1333 MT/s and 1600 MT/s. The DDR3 data
transfer rates supported by the processor is dependent on the PCH SKU in the
target platform:
— Desktop PCH platforms support 1333 MT/s and 1600 MT/s for One DIMM and
Two DIMMs per channel
— All In One platforms (AIO) support 1333 MT/s and 1600 MT/s for One DIMM
and Two DIMMs per channel
• 64-bit wide channels
• System Memory Interface I/O Voltage of 1.5 V
• DDR3 and DDR3L DIMMs/DRAMs running at 1.5 V
• No support for DDR3L DIMMs/DRAMS running at 1.35 V
