GIGABYTE 3D Power (patent pending)
GIGABYTE Z77 series motherboards take advantage of an exclusive All Digital PWM controller array, to deliver power to the board's 3rd generation IntelR Core processor. Using entirely digital controllers means that more precise power delivery to the motherboard's most power hungry and energy sensitive components is possible. These components include the CPU, VTT, processor graphics and memory, without doubt the most important components on your motherboard. This All Digital Power system, with Precise Auto Voltage Compensation, provides you with exceptional control over the component power delivery on your GIGABYTE 7 series motherboard.

GIGABYTE 3D Power: Digital Voltage, Frequency and Phase Control
Utilizing an exclusive All Digital controller array, GIGABYTE's 3D Power features precise Auto Voltage Compensation to deliver a steady flow of power to the system, no matter the loading. With digital controllers for the CPU (Vcore), VTT, processor graphics and memory (DDR), users can make real-time adjustments with the exclusive GIGABYTE 3D Power Utility, that include settings such as OVP (Over Voltage Protection), Load-line Calibration and on-the-fly PWM frequency adjustment.

GIGABYTE 3D Power(patent pending) Utility
Users can now enjoy a fully interactive 3D utility that facilitates adjustment of the 3 dimensions that control the power delivery to your CPU and Memory: Voltage, Phase and Frequency. These parameters are crucial to how the digital PWM supplies power to critical areas of the motherboard and can help users quickly obtain the highest, most stable overclock.

3D Power: Voltage Control
Voltage parameters can be modified within 3D Power, including load line calibration the of CPU. By adjusting load line calibration, Vdrooping can be avoided, maintaining optimal voltages levels despite increasing current levels. OVP (over voltage protection) can also be adjusted to change default protection range of the CPU, memory controller, VTT and system memory.

3D Power: Phase Control
Users can calibrate OCP (Over Current Protection) for the CPU, integrated memory controller and system memory power levels. This allows the Phase control to deliver even more power to the system when needed.

3D Power: Frequency Control
GIGABYTE's digital PWM allows for adjustable frequency control via the International Rectifier (IR3567) PWM controller. 3D Power frequency control allows users to change the PWM controller frequency so that the CPU VRM can adjust power delivery speeds more quickly. Users can also adjust the PWM spectrum or maximum and minimum overall frequencies

Updated Review. October 2014

The following corrections at the bottom of the page fixed all of the issues... I am using win 7 pro 64 bit. Bios F8.

Were do I start....This board has no issues with sandy bridge processors. Ivy bridge is a different story.

There is a reason why I am giving this item 5 stars. However now 4 stars.

With ivy bridge processors currently all versions of the Bios has issues. Even the Beta F8a version. However F8a is usable and stable though.
You have to call Gigabyte and ask for it to get it. This version is not available on their website.
Versions F5-F7 will cause BSOD when the computer goes into sleep mode with the ivy bridge family of processors.
Bios F7-F8a has a hard time to get into the Bios. You have to hit delete 50 times or so when you start the computer.
Sometimes you have to reset the cmos on the motherboard to get into the bios. Once you save changes to the bios that is when it becomes difficult to
enter the bios. The boot menu has the same problem. Hard to access.

However windows performance is excellent and gigabyte support is great. The engineers actually email you for tech support. They are very knowledgable.
When you call gigabyte they answer the phone in an average time of 2-3 minutes. They are very helpful and they do not read you script.
I am using core i7 3770k along with a gtx 480 gpu. 16gb ram.

They asked for the components of my system and are going to build my system in their lab to find out what is causing the issues.

I give a rating of 5 stars for the exceptional customer service. They release new versions of the bios in days not months.

Eventually all issues will be resolved. This is a very good company.

I've had this board up and running for about a week now to replace my good old faithful Core 2 Quad. Had it not been for my old motherboard failing I would still have been happy w/ the Core 2. Once the prices of Ivy Bridge come down I intend to upgrade and pass the 2600k along to the kiddies.

I was originally waiting for the release of Ivy Bridge but I saw a great deal on the 2600k so I decided to go with it. The install went well. High quality materials and great build quality. This is my first board w/ a graphical BIOS and it was ok to me. (kind of like dragging someone out of the DOS world into Windows 3.11). The BIOS felt a little clumsy to navigate through but I think that it was just me having to adjust coming from a text only BIOS.

Admittedly I don't have much patience anymore for researching proper vcore, multiplier, etc for overclocking and the stock speeds were just fine but the BIOS made it so simple to overclock that I opted to try for a mild 4.1 ghz OC. With ambient temp of 70f the CPU runs great at idle temp of 30c and after 30 minutes on prime95 63c.

Benchmarking my SSD using the Intel SATA controller and ATTO yielded a read/write of 550/515 MBs/s respectively. On a MSI z68 board with a 3rd party SATA 3 controller I was using for testing only yielded a 300/250 MBs/s read/write so I am defintiely pleased with the results of the Intel SATA controller on this board.

It's a good upgrade from a P67. If you already have an i7 sandy bridge already and realize that the IVY bridge is not much better and overheat when attempt to overclock pass the limit of the previous generation, BUT still feel the NEED of Spending your money on a new piece of tech(like me), then just upgrade your mother board to the Z77 . It is definitely a worthy purchase, in my opinion even if you already have the z68. Why?

You already know most of the features this board offers. They all work right out of the box, well after I put the system together of course. The M-sata slot is a cool little feature to show off inside a windowed case. You might have watched more than a few video unbox on youtube so am not gonna mention anything more about the feature. Except that the new placement of front audio connection port makes so much sense now than it used to be (next to the front USB ports rather than on the mid left side).

I thought the blue VRM heat sinks gonna look bad but it grew on me. Anti-static dust and humidity protection PCB makes it an appealing feature for a fairly open case. I chose to go with gigabyte because of those features. I'm not too keen with the fancy features such as thermal armor from asus or the 3 and 4 ways SLI features that higher end boards (G1 sniper, Republic of gamers). Since 2 ways is all I need, especially with my 2600k(doesn't support pcie 3.0). However this board has pcie 3.0 therefore if intel release better Ivy bridge version with better thermal output then you'd be ready to slap that new cpu on ur MB.

3D bios kinda cool I played with it a little bit. You have the 3d model of the board that you can use ur mouse to click on every parts to check or adjust the settings.
