GIGABYTE Touch BIOSTM (Patent Pending)

An Innovative New Way to Modify BIOS Settings

Navigating through the BIOS to change system settings can be a daunting task for users not familiar with control "F" functions and mouse-less navigation. While some EFI BIOS try to address this with a mouse friendly environment, many implementations still lack a certain ease-of-use necessary for most people. With GIGABYTE Touch BIOSTM, GIGABYTE engineers have completely re-imagined how users can interact with their BIOS, allowing for a more intuitive user experience. In fact, with a touch screen monitor, GIGABYTE Touch BIOSTM is as easy to use as most apps on your iPhone.

Supports Intel® Smart Response Technology

Faster than HDD-only system

GIGABYTE Z68 series motherboards are equipped with the much anticipated Intel® Smart Response Technology, allowing users to experience system performance similar to SSD only systems. Intel® Smart Response technology works by using intelligent block-based caching of frequently used applications to improve system performance and responsiveness. In fact, GIGABYTE Z68 motherboards with Intel® Smart Response Technology are able to outperform hybrid drive systems by more than 2X (PC Mark Vantage) and HDD-only systems by as much as 4X (PC Mark Vantage).

Built-in Visuals

Built-in Visuals GIGABYTE Z68 motherboards offer support for several 2nd generation Intel® CoreTM Built-in Visual Features.

Intel® Quick Sync Video

Up to 2X faster media processing than any other solution for incredibly fast conversion of video files for portable media players or online sharing.

Great product July 22 2011
By Randy Meyer - Published on
Verified Purchase
I was using the GA-H55M-USB3 version MotherBoard with a Core i7-860 just before this. I installed this MB with the Core i7-2600k and it just rocks.

One thing to note, the SATA ports are at an angle. If you have a small case you'll need to watch out for that. I am also using a Cooler Master 212 cpu cooler with a Noise Blocker 120mm Cpu cooling fan. I have one for a case fan as well and I can't ever hear the thing even when rendering in Premier Pro. This combination is unbeatable for the price.

I have Virtual Box and VMware Player installed with WHS 2011 and several other virtual machines and they run just as fast as a native install on any machine I have ever had.

I am also using it as a Hackintosh with Lion Server. Works great!

I would highly recommend this product to anyone I know. No installation problems whatsoever with Windows 7 64 bit.

It runs cool and blazing fast, nothing even makes it burp. Get one, you won't have any regrets.

Great Micro ATX board with perfect Mac OSX compatibility Sept. 7 2011
By Jonathan - Published on
Verified Purchase
Okay, first off, I bought this motherboard knowing it would work perfect with a "hackintosh" system aka run Mac OSX Lion/SL on it and pretty much get out of box support.
My rig:
Intel i5-2500k
nvidia GTX 570 ECS
8gb g. skill 1600
Lian Li v354 mico ATX case
Antec 620 h20 cpu cooler
OCZ 700w modXstream PSU

I think those are the basics. Anyway, only had to mod a few files for the GTX 570 to work (up to AMD 6870 will work without hassle). The mobo has some good overclocking tools, I just did a very basic OC to the 2500k by upping the multiplier to 4.2Ghz and the vcore to 1.32 and that's all ya need to do to get good OC out the CPU/mobo. Anyway, solid board, made of military grade stuff.

Comes with 4 SATA cables I think, two are right angled and 2 are straight through, really nice for the options. This board has a ton of options, but like I said I was most concerned about full compatibility with Mac OSX and I dual boot into Windows to game as well.

Only complaint is the CMOS battery is in between the main PCI-e 16x slot so when I screwed up some overclock setting when I was first doing it, I had to reset cmos but i was basically under my huge GPU so I had to remove that to remove the battery to reset CMOS.

But great board, no complaints everything is fairly standard fair on it. Also if you want to SLI/cross fire note that is it the top PCI-e slot and the bottom PCI-e slot that will do 8x and not the middle one, that one is 4x.

Don't order Gigabyte if you hate downtime. Sept. 27 2011
By osx86lover - Published on
Verified Purchase
I received this board last week and installed it, configured it, and after a little trial and error had OSX Lion and Windows 7 x64 running side by side. It worked fine for a few days, and then suddenly when I went to turn the computer on one day, it was stuck in an endless boot loop. Well I googled around and found that Gigabyte boards are notorious for this failure, and it's been rampant for several years!

Well that's not THAT big of a deal; I'll just call tech support right? WRONG! There IS no tech support number! You have to log on to their website and play 20 emails with someone in order to get an answer, and they take HOURS to respond. I sent an email 2 days ago tell the person what happened and I told them that I unplugged everything and removed all but one stick of ram and rebooted, and even tried clearing the CMOS, and it still is stuck in an endless boot, and what does he tell me to do? put it on a piece of cardboard and do everything I'd already done. I'm STILL waiting for a follow up. So yesterday I got tired of waiting and assumed that I'm going to get an RMA anyway, so I filled out an RMA request form. Today I get an email that it's being reviewed and I should here back in TWO DAYS!

So at this point, I've had a broken board longer than I've had a healthy one, and I have a feeling I won't be back on my computer by mid october. I thought that Gigabyte was one of the better made companies, but this customer service is HORRENDOUS! It's not like a bought a cheap board! I give them 3 stars only because when the board DID work, it did so well and it suited my needs for a reasonable price. Now I think I'm going to find an ASUS board that is DSDT compatible.

-UPDATE- They actually DO have a tech support at their main number een though the manual says they don't, and the guy was very helpful. After determining that it was either my board or CPU, he told me to contact Amazon and they would replace it. I hope my new board doesn't have this problem.

Perfect for Hackintosh! March 6 2012
By Ciaran - Published on
Verified Purchase
I purchased this motherboard for a OSX Lion/Windows 7 dual boot and so far I have been VERY happy!

At first, I thought all was lost when I put in my i7 and 16GB of RAM and it was cycling the boot process incessantly. A quick call to Gigabyte (FAST to answer customer service calls) and I reset the CMOS and we were good to go! I set the memory profile to 1600mhz and the bios to AHCI and I had nothing else to set up!

Inside the box was motherboard, manuals, SATA cables including eSATA and of course the I/O shield.

It has enough OC options to satisfy most moderate users like myself. A quick adjustment and I had a .7ghz increase on air with my i7!

One of the more popular hackintosh websites has a DSDT (motherboard driver basically) for this board, and it took me all of 10 minutes to research and download everything I needed to install OSX lion from the retail USB. Feel free to contact me via the comments for easy instructions on how to build a Mac with this board, or head over to for a tutorial!

Gigabyte gets a bad rep for their boards some time, but I have never had an issue nor a need to RMA. Their boards are stable, without too many problems, and they are always coming out with BIOS updates, which shows their dedication not only to R&D, but to current line development too!

Highly recommended! 5/5!

beware of ETRON USB 3.0 chip on this motherboard Feb. 7 2012
By Handyman - Published on
Verified Purchase
I purchased 4 of SIIG's USB 3.0 HUB with card reader and none worked with this gigabyte motherboard, so I decided to dig a little deeper and what a surprise !! It turns out the problem lies with the ETRON USB 3.0 controller chip used on many of the motherboards (regardless of nama brands)

A quick google serach on the Asus, Gigabyte, Asrock motherboard forum shows many users having compatibility issues with this specific ETRON chip and I can testify to that problem myself.

I tried Patriot USB 3.0 flash drives, SIIG USB 3.0 Hubs and Eagle Tech external USB 3.0 hard drives. NONE worked reliably on this motherboard'd usb 3.0 port !! It is a shame Gigabyte chose to go with this inmature ETRON USB 3.0 chip because all other aspects of this motherboard are excellent. As of this writing, etron only offers driver update version 1.05 but it is still plagued with stability issues. All the usb 3.0 products I tried will get detected like only 10% of the time, the other 90% of the time they simply show up as a yellow exclamation mark under Window's device manager and are not usable. When they do get detected, they will quit working after I copied 2GB or so of data. My gosh, i have never seen such a unstable USB 3.0 chip before. My other gigabyte GA-Z68XP-UD5 motherboard uses the more mature NEC/RENESSA usb 3.0 chip and has no such problems.

All other aspects of this motherboard has been working great. Its just the USB 3.0 port that really let me down.
Hope you all amazonians find this review useful. Don't get stuck with this poorly designed etron usb 3.0 chip. You might want to consider other motherboards that incorporate the more mature USB 3.0 controller chip by NEC/Renessa or buy a separate USB 3.0 card.
