Refurbished Gigabyte GA-H67MA-UD2H-B3 GIGABYTE INTEL H67 S1155 AUDIO GIGALAN -- No Warranty

GIGABYTE motherboards support Intel 22nm processors.

The GIGABYTE motherboard is fully configured to provide gamers with the latest Gen.3 PCI Express technology, delivering maximum data bandwidth for forthcoming discrete graphics cards.

Like the pistons and cylinders of a car engine, the design of the motherboard Voltage Regulator Module (VRM), component quality and number of power phases greatly affects motherboard performance. GIGABYTE engineers were first to realize not only the importance of using the best quality components for this critical area, but also that with more power phases, there can be more power available to your CPU.

GIGABYTE 6 series motherboards with their new redesigned VRM, promise to deliver first class system performance and power stability. With only the best quality components and unique design, incorporating Dual CPU Power and Power Phase Boost with Multi-gear Switching, your CPU can enjoy better power than what was available from previous motherboards.

GIGABYTE's cutting edge 8 phase power VRM design utilizes the highest caliber components to provide unadulterated, smooth power to the CPU. The innovative 8 phase power VRM has been designed and engineered to deliver fast transient response times through quick and seamless power delivery during extensive CPU loading variations. In addition, heat from the VRM is effectively reduced by spreading the load between the 8 power phases, resulting in a cooler, more stable platform.

Imagine a workstation class redundant (duplicated) power design on a desktop motherboard. GIGABYTE's proprietary Dual CPU Power Technology allows CPU VRM power phases to split evenly into 2 sets of power engines that operate in tandem.

This allows 1 set of power phases to rest while the other is active, as opposed to a traditional power design, where all the power phases are always active. As such GIGABYTE Dual CPU Power effectively halves the amount of work done by each set of power phases to significantly increase motherboard durability and reliability.

GIGABYTE 6 series motherboards incorporate an Intel® approved Intersil PWM controller that is VRD 12 (Voltage Regulator Down) compliant.

This means that it offers new features that include SerialVID (SVID) which transfers power management information between the processor and voltage regulator controller, allowing more robust and efficient signaling control between the CPU and PWM controller – hence, delivering a more energy efficient platform.

A traditional Voltage Regulator Module (VRM) consists of a Choke, Capacitors, MOSFETs and a Driver IC. By incorporating the MOSFETs and driver IC in accordance with the Intel® Driver-MOSFET specification, we can achieve higher power transfer and increased efficiency at higher switching frequencies to satisfy the growing power requirements of today's processors. Driver-MOSFETs also help to reduce VRM real estate requirements in the CPU zone.
