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