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.

Quote: Native USB 3.0The other long awaited addition found on Panther Point is the native implementation of USB 3.0 that comes directly from the chipset. The chipset will only provide two USB 3.0 ports,
------- end quote
I think Z77 natively support 4 USB 3.0 ports

When you write sentences like this:"ASUS have a lot to live up to with its Ivy Bridge Pro board."
You do realize that you're mixing a plural verb and singular pronoun for the same damn thing...Asus in this case. First, you use a plural verb talking about Asus and then use a singular pronoun for Asus in the same sentence. You cannot do both; well, I guess you can, but you show you have no clue about English grammar and look like you dropped out of third grade.
Get a copy editor! How can anyone take this site a professional when the writing borders on illiterate?

@C'DaleRider -You do realize that... you're the illiterate one, don't you?
"ASUS have" is perfectly legitimate English, and is in fact what you will hear in England itself. "ASUS" is a company of people and can be taken as singular or plural.
For me, the AT editors just made major points right in this set of comments by correcting another ignoramus, who was misusing "begs the question".
Now, can we get back to fan headers?

no, there are errors STILL all over the place in this article... it's horrid... when your site is 99% words, please make them as easy as possible to comprehend...PLEASE LEARN TO WRITE LIKE ANAND, THX!
Anand, for the love of god, pay a little more to hire a little more education (SEE WHAT I DID THAR??)

"Biostar have unfortunately put much effort in here, with only three to play with..."Should be a "not" in there I suppose.

I do not understand why non express PCI slots are still on boards. The only one to see the light is MSI, and if they had a bit better performance I would switch from ASUS for my next mobo in a heartbeat. Also, why do these boards have a VGA connector (D-sub)? Intel HD graphics can only support 2 displays max, and if you have more than you should get a dedicated graphics card anyway, and probably already have. I don't see the point.Another thing, when will OEMs start putting the USB hub at the bottom of the board facing down and not away from the board. If you have multiple cards on the board then you can get really cramped really fast when you are trying to use those.
I'm sorely tempted to just wait another year or so till there is a board with these features and over 50% SATA 6G/s, but we'll see if that even comes out in that short of time.

1) Some customers are asking for them. Customer demand was why a few boards started sporting floppy controllers again last summer. Legacy PCI demand is almost certainly much higher.2) Intel doesn't have enough PCIe lanes on the southbridge for well featured ATX boards.
2.1) This means a bridge chip of some sort.
2.2) PCIe devices are used to being able to count on the full 250/500MBps bandwidth.
2.3) Legacy PCI devices are used to sharing their bandwidth (133MBps).
2.4) 2.2 and 2.3 combined mean there's less risk of compatibility problems in filling out a few slots with legacy PCI slots.
This is probably going to remain an issue until either:
A) Intel increases the number of lanes they offer on their boards by a half dozen or so (bridges are also used for on board devices).
B) Intel integrates a lot more stuff into the southbridge so it doesn't need PCIe lanes: More USB3, Sata6GB, audio, ethernet.
C) A new version of PCIe allows sizes other than powers of two. Fitting everything on would be much easier if a board maker could fall back on just offering 13/1x or 7/7x on the main gfx slots.

GReat to see Asrock finally stepping up with the warranty, great products.James5mith - Monday, April 9, 2012 - link
Something I realized by reading this roundup:Almost all of the current motherboards are using PCI connected Firewire chips. Even the ones that have PCIe connected firewire use TI chips, which in turn are still PCI firewire, with an internal PCI to PCIe translator.
After some research the only native PCIe firewire controller I've found is from LSI. Does anyone else know of another solution? This is an interesting "dirty secret" that I never really paid any attention to.
