System Memory Support
System memory features include: 
• One or two channels of unbuffered DDR3 memory with a maximum of two UDIMMs 
per channel
• Single- 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 Intel 5 Series 
Chipset SKU in the target platform:
— Desktop Intel 5 Series Chipset platforms only support non-ECC unbuffered 
DIMMs and do not support any memory configuration that mixes non-ECC with 
ECC unbuffered DIMMs 
— Workstation Intel 3400 Series Chipset platforms support ECC and non-ECC 
unbuffered DIMMs. The platforms do Not support any memory configuration 
that mix non-ECC with ECC unbuffered 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
