Because of chipset limitations

*To avoid the system being unable to start or the memory being incorrectly detected, if only one memory module is to be installed, we suggest that you install it on the DDR2_1 or DDR2_3 socket.
*To install two memory modules, we suggest that you install them on the DDR2_1 and DDR2_3 sockets, when the DDR2_2 or DDR2_4 socket is populated with a DDR2 1066 MHz memory module, the memory speed will be downgraded to 800 MHz).
*when using FSB 1333 MHz CPU with populating all DIMM sockets, memory frequency will be reduced from the original, and system instability or incorrect detection of memory module may be occur.


Overview
Dynamic Energy Saver Advanced
GIGABYTE Dynamic Energy Saver Advanced provides better energy saving capabilities and enhanced system performance. GIGABYTE Dynamic Energy Saver Advanced is the world's only motherboard energy saving technology with hardware-based Dynamic Switching. With support for VRD 11.1, GIGABYTE's DES Advanced allows the motherboard to switch to 2 Gear phase switching during idle, allowing for a dramatic increase in power savings.

GIGABYTE has also retooled Dynamic Energy Saver to allow overclockers to experience the benefits of multi-gear power phase switching while overclocking, providing ultra stable, ultra smooth overclocking performance.

DualBIOS™ - Patented Dual Hardware BIOS Protection
DualBIOS™ is a GIGABYTE patented technology that automatically recovers BIOS data when main BIOS has crashed or failed. Featuring 2 physical BIOS ROMs integrated onboard, GIGABYTE DualBIOS™ allows quick and seamless recovery from BIOS damage or failure due to viruses or improper BIOS updating.
SATA 3Gb/s storage interface
The SATA specification doubles bus bandwidth from 1.5Gb/s to 3Gb/s. Native Command Queuing is a new specification that enables out-of-order execution of commands for efficient retrieval of data. Hot Plug support allows users to insert and remove hard disk drives without shutting off power to the system.
Intel® High Definition Audio
Intel® High Definition Audio enables 8 channel premium digital sound in the PC for an immersive surround sound experience. In addition, Intel HD Audio delivers multiple audio channels in your PC so you can listen to two different streams simultaneously in two separate rooms
Gigabit LAN connectivity
The Gigabit network interface delivers a high speed LAN connection with data transfer rate up to 1000Mb/s, providing new generation connectivity for the broadband era. Gigabit LAN is ideally for seamless internet connection such as streaming audio and video contents
RoHS compliant
As a member of the global community to look after the environment, Gigabyte complies with the European Union's Restriction of use of certain Hazardous Substances (RoHS) directive which limits the use of lead, mercury, cadmium and other hazardous substances in electronic products. From components and material selection to production processes, make up of accessories, packaging/color boxes etc; GIGABYTE has carefully examined and designed this product to be 100% RoHS compliant. GIGABYTE will continue to develop RoHS compliant PC components and commit valuable resources to promoting and advancing RoHS directive goals and objectives.
