Gigabyte GA-Z77X-UD3H WiFi—Visual Inspection
Black and blue seems to be the order of the day when it comes to mainstream boards, as indicated by some of the previous boards but also with the Gigabyte GA-Z77X-UD3H WiFi. Perhaps there is a sale on black PCBs and blue heatsinks?
Joking aside, Gigabyte intends to release two high- end boards initially—the Z77X-UD5H and the Z77X-UD3H, both in regular and WiFi variants. The WiFi variant comes with a PCIe x1 WiFi card to be used in the first PCIe slot on the board, and aerials for the outside of the case.
We have the Z77X-UD3H WiFi in to review for the launch of Ivy Bridge, which should retail for around $160 MSRP. Gigabyte has chosen a few different directions regarding which controllers are on the motherboard. This should provide interesting results when it comes to performance.

The VRM power delivery weighs in at 6 + 4 phase, which is by no means substantial (remember the ASRock Z77 Extreme4 was 8 + 4 and less expensive), and comes paired with a relatively small blue heatsink next to the socket. I’ve noticed that Gigabyte tend to have their memory closer to the socket than most other manufacturers, presumably in the name of performance due to shorter interconnects, but the downside is that it can restrict big air coolers. Nonetheless, it all still conforms to Intel specifications, and there is actually a large gap to the south of the socket.
In terms of fan headers, there are only two within reach of the socket. We have a 4-pin CPU header at the top near the memory slots, and another near the power/reset/ClearCMOS buttons at the top right of the board. The other three headers on board are found at the bottom—one 4-pin beside the SATA ports, one 4-pin next to the USB headers and another 4-pin beside the TPM.
Along the right hand side of the motherboard, Gigabyte has given us a different style of power/reset/clear CMOS button that I have not seen before. The power button is big and red, whereas the other two are relatively small. These will be of use to reviewers and overclockers, however having the ClearCMOS the same size and shape as the reset button may lead to several bad fumblings for the right button followed by several four-letter expletives.
Further down is another style choice—an additional power connector for the PCIe and system, but this case it is a SATA power connector. I prefer this to the awkward molex connectors we see on other products. Below this are the standard six SATA ports from the PCH—two SATA 6 Gbps and four SATA 3 Gbps. Below this is the handy two-digit debug display.

Along the bottom of the board, from left to right, we have the front panel audio, SPDIF header, a 4-pin fan header, the TPM header, three USB 2.0 headers, and another fan header. At the top of the PCIe is our mSATA connection, useful for mSATA SSDs and boot drives to save case space. In terms of PCIe, Gigabyte has installed a little nugget of common sense, giving enough space between the first two full-length PCIe for GPUs. However, in the x1, x16 (x8 in multi-GPU), x1, x1, x8, PCI, x4 setup, only the first two full length PCIe are for graphics output—the final one is a PCIe 2.0 x4 connector. This would be better served if it were a slightly different color to the other PCIe x16/x8 connectors. Also with two full length GPUs on board, the user will have access to two PCIe x1 connectors but the PCI connector is blocked.

I know Gigabyte will make a few people jump with joy in relation to the back panel layout—no USB 2.0! From left to right, we have a PS/2 combination port, two USB 3.0, D-Sub, DVI-D, an Optical SPDIF output, HDMI, DisplayPort, two more USB 3.0, two eSATA, gigabit Ethernet, a final two USB 3.0, and audio outputs.

One of the odd choices of Gigabyte is their network and audio controllers. On near every board I have reviewed, we get either a Realtek, an Intel or a Broadcom for the network, and a Realtek or Creative audio solution. Gigabyte has decided to jump in with an Atheros network controller, and a Via VT2021 audio. It will be interesting to see if this has an effect on our test capabilities.

This is similar to what happened with the USB1->2 transition. The newer controller is significantly bigger (read more expensive) and very few people have more than one or two devices using it per computer. I suspect the 8x (Haswell) chipset will be mixed as well; simply because the total number of ports on the chipset is so much higher than it was a decade ago (vs older boards were all but the lowest end models added more USB from 3rd party controllers).ASUSTechMKT - Monday, April 9, 2012 - link
mSATA currently has very little penetration on the market and cost wise it is much lower to purchase a larger cache SSD for the same or lower cost. We would prefer to focus on bringing implementations that offer immediate value to users.As for the Intel nics all our launch boards across the board for ATX ( Standard and above all feature Intel lan ) we have been leading in this regard for a couple of generations.
In regards to USB 3 we offer more than the standard on many boards but keep in mind many users only have 1 USB3 device.

Maybe I missed something from an earlier post, but could someone please tell me why these don't have light peak? Are they waiting to go optical and it is not ready yet? Having my USB3 controlled by Intel instead of another chip is not enough to make me want to upgrade my Z68 board...repoman27 - Sunday, April 8, 2012 - link
Thunderbolt controllers are relatively expensive ($20-30) and their value is fairly limited on a system using a full size ATX motherboard that has multiple PCIe slots. Including two digital display outputs, an x4 and a couple x1 PCIe slots on a motherboard provides essentially all the same functionality as Thunderbolt but at a way lower cost.ASUSTechMKT - Monday, April 9, 2012 - link
Almost all of our boards feature a special TB header which allows for you to easily equip our boards with a Thunderbolt add on card which we will release at the end of the month. Expect an approximate cost of $40 dollars, this card will connect to the TB header and install in a X4 slot providing you with Thunderbolt should you want it. A great option for those who want it and for those who do not they do not pay for it.DanNeely - Tuesday, April 10, 2012 - link
Sounds like a reasonable choice for something that's still rather expensive and a very niche product.Am I correct in thinking that the mobo header is to bring in the DisplayPort out channel without impacting bandwidth available for devices?

I've made it this far on my venerable OC Q6600, but I can't wait any longer. I do wish they weren't so stingy on the 6 core as I could use it, but I just can't justify the price differential (w 3 kids that is.)androticus - Sunday, April 8, 2012 - link
USB 3.0 descriptions and depictions are contradictory. The platform summary table says there are 4. The Intel diagram shows up to 4 on front and back (and the diagram is itself very confusing, because there are 4 USB 3.0 ports indicated on the chipset, and then they show 2 going to hubs, and 2 going directly to the jacks.) The text of the article says there can only be 2 USB 3.0 ports.What is the correct answer?
mariush - Sunday, April 8, 2012 - link
I think there's 2 real ports (full bandwidth ports) and the Intel solution uses 2 additional chips that act like "hubs", splitting each real port into 4 separate ports.Basically the bandwidth of each real port gets split if there are several devices connected to the same hub.
Hub as far as I know means that what the hub receives sends to all four ports (and then the devices at the end of each port ignore the data if it's not for them).
This would be different than a switch, which has the brains to send the data packages only to the proper port.

DZ77GA-70K makes DX79SI looks like a bad joke (which it is really).LGA 2011 turns into an epic fail and DZ77GA-70K is the proof. I have 1366 system and I have zero will to get LGA 2011 system thanks to the crappy tech decisions somebody made there. Six cores is the top? Again? An old 32nm process? Really? Chipset with nothing new inside but troubles? Since 1366 something strange is going on and Intel fails to see it. The end user can get better manufacturing tech for the video card than for the CPU. First it was 45nm CPU with 40nm GPU and now 28nm GPU and 32nm CPU and Intel call that high end? Really?
Everything that DX79SI should have been you can find inside DZ77GA-70K.
1. DZ77GA-70K has high quality TI 1394 firewire controller, while DX79SI has cheap VIA one that no any audio pro would ever want to deal with.
2. DZ77GA-70K has next best after Intel SATA controller by Marvell to get 2 more SATA 6.0 and eSATA vs zero extra SATA and hard to believe no any eSATA on DX79SI.
3. Intel USB 3.0 vs crappy Renesas.
DZ77GA-70K has everything to impress, including the two Intel LANs vs the Realtek that everyone else is using.
DZ77GA-70K fails in only one thing - it had to be LGA 2011, not 1155 that will be just 4 cores like forever and has zero future.
Wake up INTEL!
