This model offers native DDR2 600, eliminating the bottleneck when overclocking both the CPU and memory. With current processors supporting 800MHz FSB, ASUS motherboards, the only solutions with native DDR2 600, will provide superior performance for the most demanding applications. FSB/MEM (freq.) ASUS Other brands 800/600 (Native) V Hyper Path2 - Shorten Memory LatencyThe innovative ASUS Hyper Path2 significantly shortens the latency time between the CPU and memory and improves memory performance without sacrificing stability. Support Both DDR and DDR2 for Superior Memory FlexibilityThe P5GDC PRO supports the latest DDR2 as well as the current DDR, offering flexibility for users who need different memory performance and future upgrade option. And of course, the P5GDC PRO leveraged AI Proactive features, unique innovations on ASUS motherboards, that diagnoses LAN connection, and dynamically overclocks the system according to CPU loading. Intel 915P chipset The Intel 915P chipset supports the latest PC technologies such as LGA775 Pentium 4 CPU, dual-channel DDR2&DDR memory architecture, and PCI Express x16 graphics card interface. The ICH6R Southbridge further provides integrated 4-port SATA RAID controller, PCI Express x1 interfaces and 8 high-speed USB 2.0 ports. Intel LGA775 Pentium 4 CPUThis motherboard supports the latest Pentium 4 CPU from Intel in LGA775 package. 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&DDR2This motherboard supports 4 DDR and 2 DDR2 DIMM slots to provide ultimate flexibility for system upgrade. The dual-channel architecture allows the widest memory bus bandwidth of 6.4 GB/s for DDR, or 8.6GB/s for DDR2. 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 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. Serial ATA RAIDThe onboard Intel ICH6R southbridge provides the complete solution to your RAID requirements on different disk array standards. The Intel ICH6R supports RAID 0, 1 and Intel Matrix Storage Technology on 4 Serial ATA ports. ASUS Q-Fan TechnologyASUS Q-Fan technology intelligently adjusts fan speeds according to system loading to ensure quiet, cool and efficient operation.
