Overview

Introduction The EX58-UD5 is the latest high performance X58 Series motherboards of GIGABYTE, designed from the ground up to unleash the awesome power of Intel’s new Core i7 processors. Equipped with a host of new features including the new QPI interface, 3 channel DDR3 support, 3 Way SLI™ and CrossFireX™ support, Ultra Durable 3 technology and the industry’s most extensive range of overclocking features, the EX58-UD5 is bringing excitement back into the high performance motherboard industry.     Intel® Core™ i7 Processor and X58 Chipset support The EX58-UD5 was designed specifically to take advantage of the raw power of the next generation Intel® Core™ i7 processors and the Intel® X58 Express chipset, whose new evolution in computing architecture is able to deliver an amazing performance break through from past processor generations. Replacing the Front Side Bus is the new Quick Path Interconnect, or QPI, whose 25.6 GB/sec transfer rate (double the bandwidth of the 1600MHz FSB) eliminates the communication bottleneck between the processor and chipset. Intel® Core™ i7 processors also feature an integrated memory controller inside the processor die and support 192bit 3-channel DDR3 memory that delivers a 50% memory bandwidth enhancement and lower memory latency for incredibly fast memory access. Additionally, The EX58-UD5 features Intel® Turbo Boost Technology, which is able to power down idle processor cores and dynamically reroute the power to the active cores for significant performance boosts, and at the same time, maintain greater energy efficiency.   Integrated Memory Controller Intel® Core™ i7 Processors feature triple channel DDR3 support Intel Core™ i7 processors feature the memory controller integrated directly into the processor die, rather than as part of the Northbridge as in previous generations, allowing for faster memory performance. Core™ i7 processors also provide additional memory support including.   QPI , QuickPath Interconnect Replacing the role of FSB Intel uses the QPI to connect internal components of Core™ i7 processors , and to connect the CPU itself to the Northbridge and banks of memory. QPI delivers: Up to 25.6GB/sec of bandwidth between Core™ i7 processors and the rest of the system,providing exactly double the bandwidth of 1600 Hz FSB   Intel Turbo Boost Technology Dynamically reroutes power to improve performance For situations when all cores are not needed for a particular workload, Intel Turbo Boost Technology powers down the idle cores and dynamically reroutes the power to the active cores, boosting their performance without wasting power. This allows the active cores to achieve significant overclocks.   Multi-display support with 3 way CrossFireX and 3 way SLI™ Flexible graphics capabilities - Up to 3 VGA cards are supported for either 3 way CrossFireX™ or 3 way SLI™ action, delivering the ultimate in graphics performance for gaming enthusiasts who demand the highest frame rates without compromising on resolution.     Ultra Durable 3 GIGABYTE Ultra Durable 3 design, featuring 2 ounces of copper for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. GIGABYTE’s Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2oz Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking.   Benefits of 2 oz Copper PCB • Cooler than traditional motherboards • Enhanced durability • Improved energy efficiency • Greater margins for overclocking     2X Lower Impedance In addition, doubling the amount of copper lowers the PCB impedance by 50%. Impedance is a measure of how much the circuit impedes the flow of current. The less the flow of current is impeded, the less amount of energy is wasted. For GIGABYTE Ultra Durable 3 motherboards, this means total PCB electrical waste is reduced by 50%, which also means less heat is generated. 2 ounces of copper also provides improved signal quality, providing better system stability and allowing for greater margins for overclocking.   50,000 Hours Japanese Solid Capacitors GIGABYTE Ultra Durable motherboards are equipped with solid capacitors developed by leading Japanese manufacturers. With an average lifespan of 50,000 hours, these solid capacitors provide the stability, reliability and longevity essential to meet the power needs of high-end processors and other components running today's most demanding applications and games.   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 6-Gear* Switching. With support for VRD 11.1, GIGABYTE’s DES Advanced allows the motherboard to switch to 1 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. * The 6-Gear feature may vary by model. Gear 1 phase switching requires 45nm processors with PSI signal enabled.   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.   2 Gigabit LAN High Velocity 2X Bandwidth Boost   Hardware OverVoltage Control IC - Enabling Extreme Overclocking GIGABYTE Hardware Overvoltage Control ICs featuring more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control, which means there is no delay compared to the GPIO controller in past implementations. In addition, GIGABYTE’s Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.   Visible Overvoltage Reminder Debug LED Embedded post code LED display simplifies motherboard signals and indicates system status   OV-Alert LED 4 sets of OV-Alert LEDs indicate the overvoltage level of the CPU, Memory, North Bridge and South Bridge to prevent component damage.   Visible Overclocking Reminder OC-Alert LED indicates the level of CPU overclock from low to high.   Visible Temperature Reminder Two sets of Temperature Alert LEDs indicate the current temperature level of the CPU and North Bridge     Onboard Quick Switches Onboard Power, Clear CMOS and Reset buttons allow for quick and easy tweaking for power users working in an in chassis environment.   EasyTune6 GIGABYTE has completely redesigned EasyTune6 from the ground up to make it easier than ever to manage and monitor your hardware resources as well as tweak your system settings in order to achieve maximum system performance. Whether you are an overclocking enthusiast, or a computer novice, EasyTune6 provides the tools you need to quickly and effortlessly fine tune your system.   Dolby Home Theater® - Enjoy a Rich Home Theater Surround Sound Experience Dolby Home Theater places listeners in the middle of the action, giving their PCs a powerful set of tools to deliver a cinema-style experience in vivid surround sound.
