V1.0 Vig644M Motherboard Manual

Processor

The motherboard is designed to support the Intel Core i7, Intel Core i5, Intel Core i3, and

Intel Pentium processors in an LGA1155 socket.

Other processors may be supported in the future. This board is designed to support

processors with a maximum TDP of 95 W.

Chipset

The Intel H61 Express Chipset consisting of the Intel H61 Platform Controller Hub (PCH)

provides interfaces to the processor and the USB, SATA, LPC, audio, network, display,

and PCI Express. The PCH is a centralized controller for the board’s I/O paths.

Memory

The motherboard has two DDR3 DIMM sockets and supports the following memory

features:

 Two independent memory channels with interleaved mode support

 Supports 1.2 V – 1.8 V DIMM memory voltage

 Support for non-ECC, unbuffered, single-sided or double-sided DIMMs with x8

organization

 16 GB maximum total system memory (with 8GB memory technology).

 Minimum total system memory: 1GB using 1GB x8 module

 Serial Presence Detect

 DDR3 1333MHz and DDR3 1066MHz SDRAM DIMMs

NOTE: To be fully compliant with all applicable DDR SDRAM memory specifications, the

board should be populated with 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 DIMMs may not function under the

determined frequency.

Memory Configurations

The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors support 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 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 DIMM speeds 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

DIMM is installed or the memory capacities are unequal. Technology and device
