Desktop Board Features

Main Memory

NOTE

To be fully compliant with all applicable Intel® SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power up. The BIOS will attempt to configure the memory controller for normal operation.

The board has four DIMM sockets and supports the following memory features:

•Two independent memory channels with interleaved mode support

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

•16 GB maximum total system memory (with 2 Gb memory technology)

•Minimum total system memory: 1 GB using 1 Gb x8 module

•Serial Presence Detect

•DDR3 1333 MHz and DDR3 1066 MHz SDRAM DIMMs

NOTE

32-bit operating systems are limited to a maximum of 4 GB of memory. These operating systems will report less than 4 GB because of the memory used by add-in graphics cards and other system resources.

NOTE

When using a processor without Intel Graphics Technology, memory must be installed in either or both of the DIMM 0 (blue) memory sockets for the system to boot.

Graphics Subsystem

The board supports either integrated graphics (Intel Graphics Technology) or PCI Express 2.0 x16 graphics.

Integrated Graphics

The board supports integrated graphics through the Intel Flexible Display Interface (FDI) for processors with Intel Graphics Technology.

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 the POST whenever a monitor is attached, regardless of the HDMI and DVI connector status.
