1.3 Processor
The board has a soldered-down Intel Core i5-3427 processor with Integrated Graphics
Technology and integrated memory controller.
NOTE
This board has specific requirements for providing power to the processor. Refer to
Section 2.5.1 on page 56 for information on power supply requirements for this board.

Product Description

1.4 System Memory
The board has two 204-pin SO-DIMM sockets and supports the following memory
features:
•1.5 V DDR3 SDRAM SO-DIMMs with gold plated contacts
•Support for 1.35 V Low Voltage DDR3 (new JEDEC specification)
•Two independent memory channels with interleaved mode support
•Unbuffered, single-sided or double-sided SO-DIMMs
•16 GB maximum total system memory (with 4 Gb memory technology). Refer to
Section 2.1.1 on page 41 for information on the total amount of addressable
memory.
•Minimum recommended total system memory: 1024 MB
•Non-ECC SO-DIMMs
•Serial Presence Detect
•DDR3 1600 MHz and DDR3 1333 MHz SDRAM SO-DIMMs
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with SO-DIMMs that support the Serial Presence Detect (SPD)
data structure. This allows the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory
is installed, the BIOS will attempt to correctly configure the memory settings, but
performance and reliability may be impacted or the SO-DIMMs may not function under
the determined frequency.
Table 4 lists the supported SO-DIMM configurations.

1.4.1 Memory Configurations
The processor supports the following types of memory organization:
•Dual channel (Interleaved) mode. This mode offers the highest throughput for
real world applications. Dual channel mode is enabled when the installed memory
capacities of both SO-DIMM channels are equal. Technology and device width can
vary from one channel to the other but the installed memory capacity for each
channel must be equal. If different speed SO-DIMMs are used between channels,
the slowest memory timing will be used.
•Single channel (Asymmetric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single SO-DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed SO-DIMMs
are used between channels, the slowest memory timing will be used.
