Dual-Channel DDR2 533DDR2 is the next generation memory technology to replace the current DDR. With initial speeds from 400 and 533MHz, DDR2 memory provides bandwidth up to 4.3GB/s. Doubled by the dual-channel architecture, the widest memory bus bandwidth 8.6GB/s is achieved on this motherboard. PCI Express ArchitecturePCI Express is the latest I/O interconnect technology that will replace the existing PCI. With a bus bandwidth 4 times higher than that of AGP 8X interface, PCI Express x16 bus performs much better than AGP 8X in applications such as 3D gaming. PCI Express x1 also outperforms PCI interface with its exceptional high bandwidth up to 500MB/s. The high speed PCI Express interface creates new usages on desktop PCs e.g., Gigabit LAN, 1394b, and high-speed RAID systems. AI Proactive Stack Cool™Cooler Overclocking and Quieter Operation!Heat causes instability and shortens system lifecycle, and motherboard power circuitry is a major thermal source. The patented Stack Cool?technology utilizes a mini PCB stacked against the main PCB to conduct heat away from power components, resulting in a 10?Celsius reduction. And voila! Cooler overclocking, quieter fan operation, greater stability and longer system life without you doing a thing. WiFi-g™onboard (optional)Wireless setup made affordable and easy!WEP? SSID? Building a home WLAN used to be a hassle with confusing acronyms and cryptic menus. With WiFi-g?and its one-touch setup wizard, high-speed wireless network is just a few clicks away. WiFi-g?serves as the access point of your network or if you already have an access point, it is also a wireless adapter for PCs to access existing WLAN.(WiFi-g™ compliant to IEEE 802.11g 54 Mbps data transfer) AI NOS™Boost performance when you need it the most!Applications such as 3D games and video editing demand a huge chunk of system resource. Inject "nitrous oxide" into your CPU! The patented AI NOS?(Non-delay Overclocking System) technology intelligently detects system load and automatically boosts performance for the most demanding tasks. Unlike other dynamic overclocking techniques, AI NOS?reacts much faster to satisfy your unending need for speeds.
