4 out of 5 eggsGood Durable Board

Pros: Four 4 pin fan headers
3 year warranty
4 USB 3.0 ports and a USB 3.0 Header
Right angle SATA III connectors
Dual Bios that automatically takes over when failure occurs.
Has a temperature probe for their voltage regulators which is something I’ve never seen before.

Very durable features such as humidity protection, electrostatic protection, and surge protection.
Another interesting feature is the one fuse per USB port which is another way this board will protect itself from getting damaged as it prevents USB port failure by having a fuse for each port rather than one fuse for all of the ports.

3D Bios looks really cool and is a fairly intuitive way off going about changing settings in the bios. The only downside is that it is a little slow and lags along with the mouse cursor speed being way too slow and choppy.

The user’s manual has a helpful description of all of the RAID modes its supports, how they work, the benefits of each and how to set each of them up. Also features a very useful troubleshooting section at the back of the user’s manual for diagnosis hardware or boot related problems.

Cons: Gigabyte’s old ugly looking color scheme (New models don’t have this problem)
The SATA II connectors are not right angle

Poor USB 3.0 Read Performance:
Intel controller: Read = 213 MB/s Write = 145.7 MB/s
Etron controller: Read = 197 MB/s Write = 144.5 MB/s

USB device’s actual speed on different system:
Read = 247.7 MB/s Write = 143.2 MB/s

Mediocre built in audio with a tested dynamic range of 78.3 dB and a noise level (interference from surrounding parts) of -54.4 dB (Most motherboards I’ve tested get around -75 dB).

The Auto tuning feature is nice as it sets settings and then runs stability tests to ensure the system is stable but it tends to play it overly safe and overvolt the CPU. I would recommend using it as a starting point if you aren’t that good at overclocking and then take its number and just lower the voltage till it isn’t stable which I’m sure is a lot lower like mine was. CPU was an Intel 3770K.

• Auto Tuning OC @ 4.43 GHz
• Voltage: 1.38 volts on Vcore
• Load: 194 watts
• CPU Temperature: 180 °F
• Voltage Regulators: 136.4 °F

• Manual OC @ 4.5 GHz
• Voltage: 1.284 volts on Vcore
• Load: 171 watts
• CPU Temperature: 162 °F
• Voltage Regulators: 122 °F

Other Thoughts: There is a Beta bios and new audio driver that if both in place are supposed to improve the audio conditions but as the bios is a beta I did not test it but once they release a stable version hopefully the audio will improve.

I got the Revision 1.2 of this board in case any of it varies from others such as some getting an 8 pin supplemental CPU power connector whereas mine only has 4 pin.

5 out of 5 eggsLove this board

Pros: Lots of features, all the current tech, powerful and upgradable.

Cons: None. This is a great board

Other Thoughts: I had also been looking at the slightly higher model, GA-Z77X-UD3H, but in the end I found it unnecessary. I still have not used all the features on this board, so getting a higher one would be a waste. With 8GB ram at 1600 and a 650 ti Boost, loading screens for current games like Bioshock Infinite at max settings last just seconds at most.

There's nothing bad I can say about this board.

5 out of 5 eggsReliable

Pros: I bought an MSI board at the same time as this Gigabyte board, and the MSI failed. Gigabyte board has been rock solid. That's all I judge in a mobo, if it's working right I'm happy.

Cons: none

2 out of 5 eggsPoor driver/support/software, and bad USB support

Pros: This was included in the second machine I built from scratch, and between the knowledge I had from that build and the scarce instructions that came with this MB, I managed to get everything going pretty quickly. In general it runs pretty fast, no issues with compatibility (everything I bought worked out fine). But I feel like this should be a given for any Motherboard.

Cons: there are three major subjects I'd like to cover in the Cons category: USB, startup, and software/support.

1. USB.
- The keyboard/mouse are plugged in directly via USB 2.0 to the motherboard. About 25% of the time when the computer comes back from off or standby, the USB connection seems to be lost then regained after about 15 seconds - the keyboard (logitech G15) loses power and connectivity for no apparent reason. It then pops back on - after no physical intervention by the user.
- Also, the case's front-panel USB ports (USB 3.0) do not work at all.
- Furthermore, (probably related to the point above), there is often an error saying there is an unsupported device. What gives? It is plugged in to the correct port.

2. Startup. Again, roughly 25% of the time, when coming back from a shut-down or restart, the computer starting locks up at the BIOS "welcome" screen. No error shown or anything, just stops booting. Usually turning off the machine then turning it back on gets us past it, but that is pretty annoying.

3. Software/Support.
- The other two problems wouldn't really be problems much at all if this was handled better.
- Software: I expected a company like GIGABYTE which sells quite a few MBs to have a pretty robust suite of tools to control/monitor the machine from Windows. I assumed wrong. The @BIOS software is extremely minimal. There is no fan monitoring or any other sort of tool like that. It is impossible to see what version of the BIOS you currently have installed, or any information about your motherboard. The "About" page only talks about the @BIOS software version, which is not helpful. Looking there and in the BIOS itself, I still cannot determine if I have version 1.0 or 1.1 of the motherboard. Trying to update the BIOS using @BIOS is not straightforward, and an error pops up which causes me to scratch the process. 0/10, I would expect this in an off-brand discount motherboard, but not GIGABYTE.
- Support. The website has all the technical specs you would need when deciding to purchase this motherboard, but the support/downloads page is not very helpful. After looking around the internet, it seems like the USB issues I've found are pretty common, so I would expect GIGABYTE to have some information on how to fix it. No such luck. I'll probably put in a support request and see where I could get with that.

Other Thoughts: This purchase has turned me off from the GIGABYTE brand. The first machine I built has an Asus motherboard with similar features/cost, and it not only has no problems, especially with the built in ports, but it also has a great AISuite including fan support and ways to tweak/overclock the system if I wanted. I would not recommend this motherboard, or this brand (based solely on this purchase), to anyone that I cared about.

5 out of 5 eggsSupplemental Review

Pros: I have built two systems now with this board. Extremely easy--no difficulties with either. Fast, stable, great performer.

Cons: The only real con is the placement of two components: the 6 Gbps SATA ports come off the side of the motherboard, which is a bit awkward, and the PCIe X1 slots are clustered round the primary PCIe graphics card slot...any decent sized cooler will block the two on the right, and any card with a backplate will either block the one on the left or make it a very tight fit.

Other Thoughts: Some supplemental info: rev 1.0 boards have 4 pin supplemental power; rev 1.1 boards have 8 pin. I have one of each. The 1.0 board shipped with BIOS F16; the 1.1 shipped with BIOS F18.

I inquired of Gigabyte regarding the "On-Off Charge" function; per Gigabyte's response, the USB headers don't support this, only the USB ports on the back panel do.

2 out of 5 eggsDisappointing

Pros: feature-rich, with mid-range cost
USB3.0 header
six SATA ports (2 are SATA 6Gb/s)
UEFI graphical BIOS

Cons: reliability, no pre-POST diagnostics or status LEDs

Other Thoughts: My first board (ver 1.0) ran great for 6 months and then died without warning, locking up and now it won't even POST. No beeps, no indication why it is dead. It just doesn't work. The power supply fan runs for 5 seconds and then all shuts down. CPU, RAM and power supply work fine on an Intel board.

Gigabyte tech support responded to my online queries, but concluded I need to do a warranty RMA. They have no advance exchange program, so I'd be down for probably another 2 weeks. I bought a new one (ver 1.1) here to get back up faster, but then the new one was DOA!

Back to newegg it goes - I've returned exactly one item to them in all these years. I expect this return will be easy too - thanks newegg!

I can't keep wishing for a good board although every maker seems to have some problems. I've had probably a dozen or more stable builds with various Gigabyte boards and until now, they were my favorite.

4 out of 5 eggsCPU Power Connect Update: 8 pin

Pros: Confirming a prior review: The CPU power connector on this mobo is 8-pin, NOT 4. That's actually a good thing, higher end mobos deliver more power to the CPU. But Newegg or Gigabyte should update the product specs and the product photos. They are aged.

Cons: None, just received the mobo.

3 out of 5 eggsNew board

Pros: This board and a Core i7 CPU was intended to replace my old Core 2 system. Installation into my old box went smoothly. I like the menu-rich bios and the utilities. Still working on getting everything re-installed.

Cons: Unfortunately 2 of the PCIe slots do not work. The cards work fine, when I put them into the one PCIe slot they are recognized. Put them into one of the other two, they are not seen by the system.
