1.4 Processor
The board 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. See the Intel web site listed below for the
most up-to-date list of supported processors.
For information about… Refer to:
Supported processors http://processormatch.intel.com
CAUTION
Use only the processors listed on the web site above. Use of unsupported processors
can damage the board, the processor, and the power supply.
NOTE
This board has specific requirements for providing power to the processor. Refer to
Section 2.6.1 on page 56 for information on power supply requirements for this board.

1.5 Intel® H61 Express 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.

Resources used by the chipset Chapter 2
1.6 System Memory
The board has two 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 4 Gb memory technology). Refer to
Section 2.1.1 on page 39 for information on the total amount of addressable
memory.
•Minimum total system memory: 1 GB using 1 Gb x8 module
•Serial Presence Detect
•DDR3 1333 MHz and DDR3 1066 MHz 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.

1.6.1 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 speed 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 DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the other. If different speed DIMMs are
used between channels, the slowest memory timing will be used.

1.7 Graphics Subsystem
The board supports system graphics through either Intel Graphics Technology or a
PCI Express 2.0 x16 add-in graphics card.
1.7.1 Integrated Graphics
The board supports integrated graphics through the Intel®Flexible Display Interface
(Intel®FDI) for processors with Intel Graphics Technology.
NOTE
The board will support up to two integrated graphics interfaces plus one PCI Express
Graphics card simultaneously with required changes to the BIOS setup.
1.7.1.1 Analog Display (VGA)
The VGA port supports analog displays. The maximum supported resolution is 2048 x
1536 (QXGA) at a 75 Hz refresh rate. The VGA port is enabled for POST whenever a
monitor is attached, regardless of the DVI-D connector status.
1.7.1.2 Digital Visual Interface (DVI-D)
The DVI-D port supports only digital DVI displays. The maximum supported resolution
is 2048 x 1536 at 75 Hz refresh (QXGA). The DVI-D port is compliant with the DVI 1.0
specification.
1.7.2 PCI Express x16 Graphics
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an
LGA1155 socket support discrete add in graphics cards through the PCI Express 2.0
x16 graphics connector:
•Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (500 MB/s) per lane. Maximum theoretical bandwidth on interface is
8 GB/s in each direction, simultaneously, when operating in x16 mode.
•Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (250 MB/s) per lane. Maximum theoretical bandwidth on interface is
4 GB/s in each direction, simultaneously, when operating in x16 mode.
