Intel® Desktop Board DP55WG

Digital media is no problem on the Intel® Desktop Board DP55WG, designed for the previous generation Intel® CoreTM i7 processor in the LGA1156 socket. Extra over-clocking hardware like the post code LED and Back-to-BIOS switch will help you to reach new levels of over-clocking performance never before seen on a media series board. The new S/PDIF input and output ports and support for ATI* Crossfire and NVIDIA* SLI technology gives you the best audio and video options available.

Product and Performance Information


1. DDR3 1600 or higher memory support on this motherboard requires compatible Intel® Extreme Memory Profiles (Intel® XMP) enabled memory or advanced knowledge of BIOS and memory tuning; individual results may vary.

2. System resources and hardware (such as PCI and PCI Express*) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system.

3. Intel® High Definition Audio (Intel® HD Audio) requires a system with an appropriate Intel® chipset and a motherboard with an appropriate codec and the necessary drivers installed. System sound quality will vary depending on actual implementation, controller, codec, drivers, and speakers.
