For information about… Refer to: Memory Configuration examples htm Product Description Figure 3 illustrates the memory channel and DIMM configuration. Figure 3. Memory Channel and DIMM Configuration Intel Desktop Board DQ67SW Technical Product Specification 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 If using a processor with integrated graphics, the board will support only two of the integrated graphics interfaces simultaneously: DisplayPort, DVI-I, DVI-D. 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 DisplayPort* DisplayPort is a digital communication interface that utilizes differential signaling to achieve a high bandwidth bus interface designed to support connections between PCs and monitors, projectors, and TV displays. DisplayPort is suitable for display connections between consumer electronics devices such as high definition optical disc players, set top boxes, and TV displays. DisplayPort output can also be converted to High-Definition Multimedia Interface* (HDMI*) using a DisplayPort-HDMI converter. DisplayPort’s maximum supported display resolution is 2560 x 1600 at 60 Hz refresh with a 16:10 aspect ratio (WQXGA). DisplayPort 1.1 adds support for High Bandwidth Digital Content Protection (HDCP) version 1.3. HDCP support enables viewing of protected content from Blu-ray Disc* and HD-DVD optical media over DisplayPort 1.1 connections. For information about Refer to DisplayPort technology 1.7.1.2 Digital Visual Interface (DVI) The DVI-I port supports both digital and analog DVI displays. The maximum supported resolution is 1920 x 1200 at 60 Hz refresh (WUXGA). The DVI port is compliant with the DVI 1.0 specification. DVI analog output can also be converted to VGA using a DVI-VGA converter. The DVI-D port supports only digital DVI displays. The maximum supported resolution is 1920 x 1200 at 60 Hz refresh (WUXGA). The DVI-D port is compliant with the DVI 1.0 specification. Product Description 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. For information about Refer to PCI Express technology 1.8 USB The board supports up to 12 USB 2.0 ports and two USB 3.0 ports. The Intel Q67 Express Chipset provides the USB controller for the 2.0 ports. The two USB 3.0 ports are provided by the NEC* UPD720200 controller. The port arrangement is as follows: • Two USB 3.0 ports are implemented with stacked back panel connectors (blue) • Four USB 2.0 ports are implemented with stacked back panel connectors (black) • Eight USB 2.0 front panel ports implemented through four internal headers All 14 USB ports are high-speed, full-speed, and low-speed capable. The USB 3.0 ports are super-speed capable. NOTES Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use a shielded cable that meets the requirements for full-speed devices. In order to use supported USB 3.0 features, you must first install the USB 3.0 drivers. Operating system installation may be interrupted if keyboard and mouse devices are connected to the SuperSpeed USB 3.0 ports (blue) during installation due to the lack of native USB 3.0 driver support from the operating system. For information about Refer to The location of the USB connectors on the back panel Figure 9, page 46 The location of the front panel USB headers Figure 10, page 47 Obtaining USB 3.0 software and drivers Section 1.3, page 16 Intel Desktop Board DQ67SW Technical Product Specification 1.9 SATA Interfaces The board provides six SATA connectors through the PCH, which support one device per connector: • Two internal SATA 6 Gb/s ports (blue) • Two internal SATA 3 Gb/s ports (black) • Two backpanel eSATA 3 Gb/s ports for external connectivity (red) The PCH provides independent SATA ports with a theoretical maximum transfer rate of 6 Gb/s for two ports and 3 Gb/s for four ports.
