Gigabyte GA-Z77X-UD3H - In The Box
Over the past several motherboard generations, I have not been that impressed with Gigabyte's offering in terms of extras - this is because in order to hit a price point, sometimes the extras in the box are not the focus of the product. With the Z77X-UD3H, we are hoping for at least some good stuff here.
Driver CD
User Manual
IO Shield
Four SATA Cables
One long SLI bridge
Voltage Readings
Using OCCT we monitor the voltage change of the motherboard under load. This represents the direct correlation between the Load Line Calibration and how the processor/motherboard deals with voltage requests while under load. This is not to be confused with the quality of power delivery, but more an indication of how aggressive the default LLC settings are on a motherboard.
The response of the Gigabyte board under load is fantastic. No ripple at all and a lower average voltage than the ASUS P8P77-V Pro.
Overclocking
Note: Ivy Bridge does not overclock like Sandy Bridge. For a detailed report on the effect of voltage on Ivy Bridge (and thus temperatures and power draw), please read Undervolting and Overclocking on Ivy Bridge.
The Gigabyte GA-Z77X-UD3H has a variety of overclocking tools at the disposal of the user. Automatic overclocks are through EasyTune6, where we experienced a rather good result with our chip with Gigabyte's auto tuning software, and manual overclocks are either performed through the BIOS (with a series of menu jumps which should have been more carefully laid out), or using a new Gigabyte tool called TweakLauncher. I have not previewed TweakLauncher here, as it is primarily for sub-zero overclockers wanting real-time access to changes in performance while under extreme temperatures. It forgoes the usual GUI interface and sliders with something more amenable to the competitive overclocker - it is not suitable for the majority of users.
Auto Overclock: Using the Auto Tuning option in EasyTune6, the software pulled up a large screen and offered a confirmation of a stress-tested overclock. When clicked yes, the system would stability test a range of BCLK and Multipliers until the board resets or the system finds it unstable. When this had finished, the board offered me a 46x104.5 overclock (4810 MHz). I discovered that turbo modes still applied, so this speed was the single thread speed, and the CPU would reduce the multiplier by two for multithreaded loads, giving 4589 MHz). This gave 1.236 volts at load, which could be a little high, but due to the lower speed under multithreaded load, the CPU only reached 84ºC under PovRay and was completely stable. I enjoyed this result a lot from an automatic overclock!
Manual Overclock: Due to the way Ivy Bridge behaves with increased voltage, for a manual overclock, I am testing the peak overclock at a variety of voltages as well as the temperatures at that voltage. On the Gigabyte board, the CPU load line calibration was set to Extreme and Intel Speed Step was disabled. One interesting thing to note was that Gigabyte set this board to 100.9 MHz default on the BCLK, rather than 100.0 MHz. When the multiplier is pushed above 44x, this is reduced to 100.0 MHz.
At 1.100 volts, the highest multiplier that was stable was 45x, giving 4.5 GHz. This gave 70ºC at load with PovRay, and showed a load voltage of 1.116 volts.
At 1.150 volts, the highest multiplier that was stable was 46x, giving 4.6 GHz. This gave 75ºC at load with PovRay, and showed a load voltage of 1.164 volts.
At 1.200 volts, the highest multiplier that was stable was 47x, giving 4.7 GHz. This gave 82ºC with PovRay, 86ºC with OCCT, and a load voltage of 1.212 volts.
At 1.250 volts, the board successfully booted at 4.8 GHz, with 1.272 volts under load and 89ºC with PovRay - but this was not stable due to the memory errors in PovRay, suggesting more voltage is required. Given the current load temperature, I was unwilling to push the voltage further.
In terms of memory, when attempting to overclock a G.Skill 2x4 DDR3-2666 kit, which performed 2950 MHz on the ASUS P8Z77-V Pro, it would not boot at the DDR3-2800 strap despite all the correct timings being entered.

Yes, it is a very important feature. The Ivy Bridge IGP can drive 3 monitors. 4 display outputs means 3 of them are digital.Discrete GPUs increase idle power consumption, an as of this post none of them have particularly good open source drivers. Some of us just want lots of screens, good compiz performance, and silence.

I have been building a series of matx htpc/gamer machines.I have one with the basic
Gigabyte GA-B75M-D3H mATX board
and one with the
Gigabyte Ga-h77m-d3h mATX board.
I want to decide between
the ASUS P8Z77- m pro mobo or
the ASUS p8z77-m board and
last but not least the
Gigabyte Intel Z77 LGA 1155 AMD CrossFireX/NVIDIA SLI DVI/HDMI/DisplayPort Dual UEFI BIOS mATX Motherboard G1.SNIPER M3 .
I am liking the two builds I did with the lowend gigabyte boards and some intel i5 t2500t cpus I want a better board but I don't have many reviews to go by.

It just doesn't make a whole lot of sense to me. Are most DIY'ers really opting for ATX? Should they? I'd bet most people only plug in a video card and maybe one other card such as wireless or even a tuner. Every other possible need they may have would not only be met by mATX but even ITX is pretty full featured these days.You'd think mATX would be what most boards are targeted at, and leaving ATX for extreme builds/bragging rights. It's just like those high end video cards, most people don't buy those, rightfully and importantly so. Those should be the premium prices, and mATX should have a lower price. The focus just feels off.

You mentioned people want mATX board. There by itself probably means that it can command higher prices, due to higher price tolerance of the purchasers.Caeric - Monday, May 7, 2012 - link
Enjoyed the review. I still have an old AMD dual core, and I'm considering a new system in the next couple of months so these help a great deal.I did find one error in the article, under the ASUS board:
"The ASUS P8Z77-V Pro retails at $225-$235, essentially $100 less than the ASRock Z77 Extreme4..."
It should say "...essentially $100 more than the ASRock..."

Curious as to this controllers' performance vs the ever present Marvell controllers. Does it use a pci-e lane or usb3 for it's bandwidth?FozzyofAus - Monday, May 7, 2012 - link
Great review.I'm leaning towards mATX as well for this build as I've never used more than four expansion slots and currently I'm only using 3 (one is USB3 which won't be needed in the new board).
I'd like to have a bit more room in my current case and the option to reuse this motherboard in a smaller case in future if I upgrade my main rig to Haswell next year.
Any chance of adding Asrock Extreme4-m to the next motherboard roundup?

Sorry guys but this review was a bit average. Comment on the various different controllers used by the motherboard manufacturers but don't offer any kind of review on them?The good additions: DPC latency and boot time.
The missing? Well everything else.
I was especially hoping for a comment on the VIA audio on the UD3H - it's been a while since I've seen VIA codecs on mainstream boards.
I'm also amazed that you didn't slam the ASUS board for it's price and lack of features. Realtek 892? On a board that's nearing twice the cost of the ASRock? Seriously?
No comment on the durability of the boards either? Hrm. No separation in testing of the different controllers on each board?
A bit lacking, sorry.

Perhaps you're commenting on the wrong review.As Ian stated multiple times throughout the review, Asus is using Intel NIC's on their boards, in this case, the Intel 82579V.
Durability is a function of time. Please point out the other motherboard reviews that covered durability.
spronkey - Thursday, May 10, 2012 - link
He stated ASUS were using Intel, sure. But didn't get into any details other than stating they exist about the fact that there are multiple USB3 controllers and SATA controllers on each board. No benchmarks comparing them etc.In fact does it even mention which controllers were tested?
And Durability is a function of construction quality and time. It would be nice to see comments on points such as board weight and flex, quality of soldering, quality of components used on the board (according to an electrical minded person on OCN, Gigabyte uses significantly higher rated MOSFETs than other manufacturers), temperatures of chipsets and VRM circuitry. These are things I can't easily find out by reading manuals.
