technologies such as Maximum Power Delivery technology, Dual CPU Power
technology and Ultra Durable 3™ design just to name a few, that ensure a
reliable and enjoyable computing experience.
Maximum Power Delivery
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.
12 Phase Power Design
GIGABYTE's cutting edge 12 phase power VRM design utilizes the
highest caliber components to provide unadulterated, smooth power to the
CPU.
The innovative 12 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 12
power phases, resulting in a cooler, more stable platform.
Dual CPU Power Technology
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.
New 100% Hardware VRD 12 Compliant CPU Power Design
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.
Driver MOSFETs - Integration of VRM Components

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.
108dB Signal-to-Noise ratio playback
GIGABYTE strongly believes that in 2011, HD audio playback is a
standard specification, and as such, we have made Blu-ray audio playback
a standard for all of our motherboards.
All of GIGABYTE's 2011 motherboards feature higher capability audio
solution with 108dB Signal-to-Noise ratio (SNR) playback quality to
deliver high-performance, multi-channel HD audio. SNR is a comparison of
the amount of signal to the amount of noise such as hiss present in the
signal (expressed in Decibels). A higher SNR equals a better audio
experience. For example, 108dB, is a high audio specification, as this
means the audio signal is 108dB higher than the level of the noise.
DualBIOS™ 3TB+ HDD Support (Hybrid EFI Technology)
Hybrid EFI Technology combines the benefits of GIGABYTE's mature BIOS
platform including stability and compatibility with 3rd party products
with 3TB+ HDD support from EFI technology, allowing GIGABYTE to offer
the best of both worlds through a quick and easy BIOS update using
GIGABYTE's @BIOS utility that is freely available from the GIGABYTE
website.
GIGABYTE DualBIOS™ is a patented technology that automatically recovers
BIOS data when the 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. In addition, GIGABYTE DualBIOS™ now supports 3TB+
(terabyte) hard drive booting without the need for partitioning, and
enables more data storage on a single hard drive.
Ultra Durable 3
The GIGABYTE Ultra Durable™ 3 design features twice the copper for both
the power and ground layers of the PCB, dramatically lowering system
temperature by efficiently spreading 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 2x Copper layer design also provides improved signal
quality and lower EMI (Electromagnetic Interference), providing better
system stability and allowing for greater margins for overclocking.
On/Off Charge Technology
GIGABYTE On/Off Charge technology allows you to charge your iPhone,
iPad and iPod Touch regardless of whether your PC is on, in standby mode
or even off. A derivative of GIGABYTE's highly acclaimed 3x USB Power
feature, On/Off Charge enables devices to draw more current from
GIGABYTE motherboard USB ports than standard USB ports allow, so that
charging from your PC can be as fast as with a charger...
