Introduction to the Gigabyte P67A-UD4 Socket 1155 Motherboard

With the whole P67 technology for Sandy Bridge upon us, every motherboard manufacturer has pulled out all the tricks to get the buyers to decide in their favor. We have seen it all over the web as companies have sent out sample motherboards, even long before the processors were released. For anyone who was fortunate enough to receive a Sandy Bridge processor before launch, could not release any performance numbers, specifications or pricing anyways. So, until now all we could do is go by manufacturer’s press releases and the word of a few hardware websites.

One company that we saw some interesting samples for was Gigabyte. A long time top tier manufacturer of motherboards, Gigabyte has released some of the best performing motherboards on the market. Many have even broken a few world records. Yet for many of us it’s not about broking records, it’s about how well the motherboard is going to perform for us on a daily basis.

Closer look

The first thing that you can't help but notice about this new P67A-UD4 (henceforth referred to as UD4) motherboard is the complete change in color scheme. Gigabyte decided to move on to a black theme for the P67 line-up, though the H67 line still maintains the blue theme we are accustomed to. Many like the fact that Gigabyte's board has a true black PCB, not a black-like color like that of some the competitors. The reason for that black-like (almost brown in certain light) is because, as we all know, motherboards incorporate a lot of copper and it's all those copper-orange traces which cause that brown hue when painted over by black. What Gigabyte has seemingly done is added a top PCB layer just for the black matte color, thus preventing the copper's color imposing a brown hue in places.

Being the mainstream model of the series, the UD4's CPU power section are cooled with decently sized heatsinks for the MOSFET voltage regulation circuit. You shouldn't have any issues with mounting a large CPU cooler given the ample amount of room provided. The UD4 uses 12+2 power phase configurations to distribute adequate power to the CPU and its integrated memory controller. One of the advantages Gigabyte uses to promote their motherboards is ‘2 oz copper’, which means Gigabyte incorporates 2 oz of copper for both the power and grounding layers. This not just helps by providing an increase in power efficiency, but aids in the cooling as well, which combined result in stable operation at a potentially higher overclock.

The UD4 comes equipped with dual full length PCIe 2.0 slots. When using a single GPU the top slots runs at the full x16, and in an XFire or SLI configuration the bandwidth drops to x8/x8. Which yes, you read correctly, this motherboard supports both CrossFire and SLI for a better gaming experience. There are also three x1 PCIe and two standard PCI slots on the motherboard, which one of each will be rendered unusable if running two graphic cards.

The Sandy Bridge processor has a default [native] integrated memory controller speed of  1333MHz DDR3, but no worries as the motherboard itself can support up to 2133MHz memory when overclocked. Through the four DIMM slots the motherboard there is support for up to 16GB of ram when using 4GB memory modules. The motherboard does support Intel’s XMP, so the input of the correct timing parameters is easier as the end user only needs to enable this feature.

The UD4 has a total of six SATA ports with two being SATA III, with the remaining four being SATA II, and support the more popular forms of RAID: 0, 1, 5 and 10. These six ports are directly through the CPU’s PCH chip, which is cooled by the heatsink in the background of the first shot shot below. The second photo shows the internal USB 3.0 header for an addition two connectors. This is nice as many of the new cases coming out are equipped with front connectors and this should help eliminate the need for running a USB3 cable out to the back panel. Missing from the boards is the floppy and IDE controller which are not supported by the chipset and so are optional add-on features. (Editor's Note: Speaking of add-on features... The PCI slots you see are also not natively supported by the P67 and are run off an integrated bridge adapter through a PCIe x1 lane, and is provided by the ITE chip off to the right of the PCI slots. You can actually see it on the left side of the USB3 header shot, to the left of the two silver/blue capacitors . So if you start to see an influx of boards without PCI slots, it isn't due to the manufacturers leaving out features the P67 supports, but simply because it actually doesn't. Just a friendly FYI!)

Gigabyte put some time and thought into this, and gave the UD4 motherboard a nicely laid out rear I/O panel. There are a total of eight USB 2.0 ports, two are at the far left and sit above the combo-PS/2 port. Next to them are optical and coax digital audio, then four more USB2 and two powered eSATA for external storage. There are two of the typical blue colored USB 3.0 ports, controlled via an onboard Renesas (aka NEC) chip. The onboard Gigabit network port comes next, followed by the remaining two USB2 ports. Finally are the 7.1 Surround and Mic/Line-In connections that come by way of the Realtek ALC892, which is Dolby certified and should offer some decent sounding digital audio.


The BIOS of the UD4 is something that most of us are familiar with. As of now there is UEFI interface like on the ASUS(P8P67, Pro, H67 M-EVO) and ASRock(Pro3) motherboards we have reviewed. Not quite as fancy as the UEFI interface, but the nice thing is that we knew just where to go to set up everything we needed to get the benchmark session going.

Gigabyte has packaged the P67A-UD4 with some rather fancy features. They lead the field with their 24 Power Phase motherboards, which help by supplying the CPU and memory controller with enough power to operate stably at even the highest overclocks. The UD4 may seem as though it is not as high end  with only 12+2, there are a few things to consider. First is the easiest and that is the fact the UD4 is not exactly an "enthusiast grade" motherboard. While it is by all means a high end product, it is still aimed at the mainstream market, and so such a feature isn't entirely necessary; however, that is where the second part comes in.

The UD4 comes with a new "Driver MOSFET" that will help increase the output and efficiency of the VRM circuit. To give a basic idea how things went before is you had a High side and a Low side MOSFET, and then a single driver for both. That is in addition to the ferrite chokes and capacitors as well, but all in all you basically end up with one Phase (channel). Then you do that, so many times, until you have your desired configuration. Take fore example the Gigabyte 890GPA-UD3H with it's 10 Phase (8+2) design. Basically means you are ending up with a rather healthy number of MOSFET, choke, capacitors and drivers for ONE Phase! Now multiply that by ten, and I think you'll see where we're going. Point is, Gigabyte go away from that now and they run the Driver MOSFET. Whats that means? Well the switching can occur much faster, no more passing energy between a high-side and low-side, thus allowing for a quicker transferal of energy to the CPU. This new bit of silicon has the MOSFETs and driver all rolled into one nice packaging, and so is aptly named Driver MOSFET.  As we all know, when you are able to put more critical components together into a single piece of silicon, the efficiency will increase as a result. Which that efficiency in turn offers more than one may think; heat output. An example of those two things: The integration of the memory controller onto the CPU which greatly increased bandwidth, and the increased efficiency of a power supply results in a far cooler operating temperature. Not only has additional space been opened up by requiring fewer components to complete the same task, but manufacturing costs come down as well. 

To summarize: Less components = less Heat which = better overclocking potential. The greater efficiency equates to getting the same output capability, while not having to use as many phases. We're not saying 12=24, but it bring it closer! So you can imagine how well the P67A-UD7 with 24 Driver MOSFET phases will perform!

By now we are all familiar with Gigabyte's patented Dual BIOS feature, which as the name implies means the motherboard physically has two BIOS chips. This is a very helpful feature for both the newbie and enthusiast, which 'enthusiast' in this case would be a BIOS modder. To relate that to a user experience, say you've done some hard core BIOS setting tweaks and well, they just didn't work out. Instead of a CMOS reset, the second BIOS will kick in and allow you to POST, go in, and not lose all your settings. Sure, the competition can do that with one chip, but that's where the latter comes in. If you've made a BIOS modification and it went south, with a single chip you'd need to do what they call a "hot flash", which only then is possible if your BIOS chip is socketed! If it is soldered on, well you've got a corrupted chip and a new one (preferably already flashed) will need to be soldered on; not fun, not at all. With Gigabyte's Dual BIOS you needn't worry. The second one will kick in just like before, but this till it will detect a corrupted primary chip and flash it back to working order, automatically! We don't recommend modding a BIOS, but it is a nice peace of mind, given a bad flash can easily occur during a manufacturer released BIOS. As the saying goes: Sh...stuff happens! 

Ultra Durable 3 is another feature Gigabyte has been employing for at least a year now. Plainly put it means a motherboard with that label comes equipped with USB 3.0, 3X USB power (higher current output) and SATA 3.0 (6Gb/s). It was such a successful naming convention that even the other companies have picked up and incorporated their own variations. "Competition breeds innovation" they say, and it is true.

Cloud OC is a fairly new tool. With the software it allows the user the ability to overclock the system through any web connected device. So a Smartphone, tablet, netbook, et all, if it's connected to the internet and you're running Cloud OC then you have complete control. We see it as a novelty for the standard user, but quite a useful tool for the competition overclocker where in a multi-person team. One could be say, pouring the LN2, where the other is standing out of the way and overclocking from a tablet.

Overclocking the Gigabyte P67A-UD4

The Gigabyte P67-UD4 is the ideal match for the more popular i5 2500K. In our testing we managed an incredible 4700MHz using a retail version CPU, not an engineer sample which consumers do not have access to. This speed was done using a modest 1.4V on the CPU, and 1.65V for the DDR3.

Tech ARP x264 HD 3.15
Simply put, it is a reproducible measure of fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It's nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other.

We have here another fine example of what Gigabyte is doing for the DIY computer building community. For either the gamer, enthusiast or overclocker the P67A-UD4 is a great motherboard that offers a lot in the form of features that are unique to Gigabyte. Honestly, what surprised us was the change in color combination on the motherboard. Gone is the light blue that have adorned Gigabyte's boards for many years, and replacing it is a beautiful black PCB, one that is truly black and not some brownish-black.

One of the wonderful aspects of the P67 chispet, and reasons people from even higher end predecessors are changing from, is the overclocking ability and increased memory bandwidth. Both are fun to play with as well as benefit us while gaming, benching or doing routine tasks. Yes, we can rely on the Intel SpeedStep to take our CPU to the next level but the fun is pushing the envelope with this board, either by using the EasyTune software or the old fashion way in the BIOS.

In the case of this motherboard we took a retail version i5 2500K and pushed it to 4.7GHz with ease. Sure, more could possibly be gained with additional tweaking and time, but even with just playing around in the BIOS we have never been able to do this with air using older chipsets, short of some kind of golden CPU that was touched by the Gods of computing.

The UD4 is placed in the middle of Gigabyte's P67 lineup. Priced at roughly $190, the UD4 should be a great seller for Gigabyte but we would have liked to see at least one added feature at that price point: onboard power, reset, and CLR CMOS button. The UD4 will be on the bench table of a lot of users and these buttons would be very handy.
