With 800MHz FSB, 1 MB L2 cache, Hyper-Threading Technology and core-speeds up to 3.6GHz and beyond, Intel's LGA775 Pentium 4 is one of the fastest desktop processors to date."Attention!! CPU Installation" Dual-Channel DDR&DDR2DDR2 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. Intel Graphics Media Accelerator 900 The new Intel Graphics engine has new capabilities that provide a significant increase in graphics performance. DirectX 9 hardware acceleration, 333MHz core clock, and large video memory all together provide a full-value, high performance graphic solution to you. Through a dual-independent display technology, different content can be displayed on each monitor or stretched across both displays for more workspace. 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. 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. AI NET2 Diagnose LAN connection before entering OS!Network problems are often caused by bad cable connection. AI NET2 remotely detects cable connection the second you turn on the system, and any faulty connections are reported back up to 100 meters at 1 meter accuracy. High Definition Audio Enjoy high-end sound system on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature, retasking functions and multi-streaming technology that simultaneously sends different audio streams to different destinations. You can now talk to your partners on the headphone while playing a multi-channel network games. All of these are done on one computer. The Dolby Digital Live technology from Dolby Lab encodes the multi-channel audio source into AC-3 bit-stream and outputs it to S/PDIF port in real time.
