Gigabyte H77-D3H Motherboard Core i3/i5/i7/Pentium/Celeron Socket LGA1155 Intel H77 Express ATX RAID Gigabit LAN

Product Overview


3rd generation Intel Core processors are based on the 3rd generation Intel Core processor architecture, manufactured using the latest 22nm process to create a visually optimized processor platform. Based on the mature LGA 1155 socket, 3rd generation Intel Core processors feature up to four high-performance 64-bit processor cores and 8MB of L3 cache Smart Cache, and overall performance when you need it most. GIGABYTE 7 series motherboards take advantage of the latest connectivity and expansion bus technologies available on the Intel platform. The 3rd generation Intel Core processor platform debuts the new PCI Express gen. 3.0 expansion bus, allowing users to take advantage of the next generation, high-bandwidth discrete graphics card solutions. Intel Rapid Start Technology gets your device up and running faster from even the deepest sleep. This means users will be able to experience almost zero power draw from their PC, but be able to resume Windows 7 is a few seconds without having the PC go through a full system boot. With Intel Rapid Start Technology the previous session resumes to the exact as it was, so that applications are still in the same state and no application data is lost. Intel Smart Connect Technology means that your email, favorite apps, and social networks are continually and automatically updated even when the system is asleep. No more waiting for the latest world news or friends' updates to be delivered-just press the 'on' button and you're up-to-date and ready to go. The GIGABYTE EZ Smart Response utility is a simple application that allows users to quickly and easily configure their system for Intel Smart Response Technology. In the past, enabling Intel Smart Response meant users needed to enter the BIOS in order to configure their system for RAID mode, which then required a complete reinstall of the operating system. Once that processes was complete, users then needed to install the Intel Rapid Storage Utility as well as configure Intel's Smart Response Technology. GIGABYTE EZ Smart Response does all of this automatically, without users having to perform a complicated install process. This allows them to quickly and effortlessly enjoy a significant boost in system performance.


GIGABYTE EZ Setup is an exclusive application that allows GIGABYTE 7 series users to more easily configure and setup three important Intel Technologies on their new system; Intel Smart Response, Intel Rapid Start and Intel Smart Connect. GIGABYTE EZ Setup makes it far easier to enjoy these technologies by greatly reducing the number of steps involved to install setup and configure your system. GIGABYTE 7 series motherboards feature an onboard mSATA slot allowing users to easily take advantage of advanced SSD-based technologies like Intel Smart Response and Intel Rapid Start. Mounting an affordable, low capacity mSATA SSD directly onto your motherboard can enhance your PC's performance with better overall desktop responsiveness, faster boot times and faster system resume from 'Suspend to Disk' and 'Standby' modes. GIGABYTE motherboards boast SuperSpeed USB 3.0 technology made possible through an additional onboard host controller. With superfast transfer rates of up to 5 Gbps, users are able to experience a theoretical 10x improvement over USB 2.0. Additionally, backwards compatibility with USB 2.0 assures users of long term use of their legacy USB 2.0 devices. GIGABYTE motherboards are High-Speed SATA Revision 3.0 compatible, delivering superfast 6Gbps link speeds for twice the data transfer rates of SATA Revision 2.0 (3 Gbps). When used in RAID 0 (Stripe) mode, they offer even faster data transfer rates of up to a theoretical 4x the speed of current SATA interfaces. GIGABYTE motherboards feature a 3x USB power boost, delivering greater compatibility and extra power for USB devices. GIGABYTE's unique USB power design is also able to efficiently regulate output over the full voltage range, which greatly enhances USB device compatibility. In addition, dedicated lower resistance fuses ensure lower voltage drops, and provide more stable and plentiful power delivery. GIGABYTE LAN Optimizer is designed to allow the user to manage different types of network traffic so that data streams such as HD media, web browsing or online gaming can be prioritized, taking precedence over large data downloads that tend to strangle overall network bandwidth.
