1 out of 5 eggsNot so ultra-durable

Pros: Cooling

Cons: Ergonomics of board layout. Gygabyte customer support is non-existent.

Other Thoughts: Board died after 3 years of use. The atx keeps shutting the system down. Started slowly approximately once a week and progressed to where it wont stay powered on at all.

5 out of 5 eggsGreat board

Pros: Great board with tons of OC options. Running my E8600 at 4.5Ghz stable daily. Dual bios works without a hitch. No problems whatsoever. Last board made with LGA775/DDR3 support.

Cons: None.

2 out of 5 eggsat least it looks cool

Pros: looks cool
3-year warranty

Cons: Ever since this was new, it would glitch the video and audio. Their EZ over-clocking utility thing is absolute junk and couldn't even OC .1GHz without crashing. Finally, after swapping EVERYTHING out with my MSI rig (which works perfectly BTW), I'm sending this back for a replacement because the audio and video skipping is simply intolerable.

Other Thoughts: For an 'ultra durable' board, it sure doesn't seem to be living up to its claims. I'm hoping they'll replace this with the new version 1.3 and that it will live up to their claims a lot better than this one did.

5 out of 5 eggsSo far so good

Pros: Very nice design, decent spacing and cooling for bridges. New build 12/2010 with new parts from
Utilities like OC Guru and EASY TUNE 6 are useful for monitoring system temperatures.

Cons: Takes some time to go through the amazing amount of BIOS settings available. Be really carefull in using EASY TUNE 6...

Other Thoughts: Did crash system after using EASY TUNE 6, tried the lowest setting and immediately got the BSOD. Had to pull the CMOS battery and re-do everything, again. Real issue may be with another GIGAGBYTE product, a GIGABYTE GV-NX96T512HP GeForce 9600 GT video card with passive cooling. It has been overheating since day 1?, but just discovered this after monitoring GPU temperatures after some gaming caused System Crashes. Might be the true cause of the BSOD...waiting for RMA of the card. Using the instruction manual for this MB gets easier every time that I try changing something or read about related MB issues. So far, all is working great. Need a PS2 keyboard on the bad days, as the USB keyboard is NOT recognized during hard shutdowns and restarts.

1 out of 5 eggsGood, but not great

Pros: Great features list and right out of the box I was able to up the speed with very little effort.

Cons: It has some issues that Giga doesn't seem to want to work on. When the disk drives are running it will pause like it has frozen only to come back to life with no problems. It does this OC'd as well as stock. I've reloaded windows and it still happens. All this hardware worked perfectly on the old P45 DDR2 board I had before this so the only item that has changed is probably the cause. Giga offered to RMA it for me, but I shouldn't have to RMA a board so they can claim it works with their equipment. I work in IT and this is an issue with the board and its BIOS. I think they just don't care to update it because the 775 socket is on the outs.

Other Thoughts: If Giga would just update the BIOS and give this board a little love I think this could be an awesome buy. As they don't seem to think the board has issues or conflicts I don't think they will be fixing it anytime soon. Well good thing bulldozer is around the corner, but bad for Giga I won't be buying their products due to this board.

2 out of 5 eggslast resort

Pros: It still works if I never shut it down- but still never promising.

Cons: I have to say that this board is not at all very stable. Bios is extremely buggy, gigabytes own raid controller is a joke, pwr/rst/hdd led's stopped working after a month. Both freezes/hangs on post. I have to just leave it on all the time, otherwise I dont know if I will have a working machine the next morning.

Other Thoughts: This was purchased as a last resort replacement. Not currently ready to upgrade, I bought something I thought I could rely on to hold me over. Sadly, with the bugs, and random errors this motherboard comes up with. I do not feel I can trust my hardware with it. However if you are were stuck like I was (775/DDR3) and do not tend to overclock it too much. It may work for you. I personally will never purchase a gigabyte product again.

1 out of 5 eggsDisappointed, DPC's are way too high

Pros: The board has a great feature set with support for DDR3, RAID, Firewire, and USB 3.0

Cons: With EIST and C1E settings turned on the board generates hi DPC levels.

I believe that this board is in serious need of a BIOS upgrade as green features are not usable if you need to get DPC's down to a reasonable figure. I don't see why Gigabyte would release a board with such obvious flaws.

Without a BIOS upgrade the buyer is not getting the quality and feature set that is advertised.

Other Thoughts: This board replaces an Abit IX38-QuadGT motherboard. I thought it would be nice to have a board that supported DDR3 and USB 3.0. My processor is a Q9650 CPU. I do not overclock.

I use the computer with my amateur radio. The radio uses the computer for real time digital signal processing of signals from the radio that are processed and converted into audio. The audio quality was terrible with clicks, distortion, and stutters. Sometimes the radio software would just hang.

Running DPCLAT.EXE revealed that DPC's would run as high as 6,000us, far too high to be usable for real time signal processing. I disabled as many devices through Device Manager as possible to no avail. My Abit board never had issues with DPC's but this board is a major disaster.

I found that disabling EIST and C1E in BIOS brings the DPC's down to the 100-to-200 us range. That is fine for my applications, but also prevents the ability to use power management features.

I am disappointed in Gigabyte.

5 out of 5 eggsI love it

Pros: 1) The dual copper really does make a cooling difference. I thought it was just a marketing ploy until I opened it up. I touched the back and it felt cold, very, very cold.
2) The board comes with heatsinks on the cpu mosfets, the north bridge and the southbridge. The cpu mosfets and northbridge sinks are connected through piping to help transfer heat around, is pretty helpful considering that people pump air out out sometimes through the back, sometimes up, and sometimes have no air hitting north bridge,
3) Mosfets seem to ensure reliable power.
4) Can run Xfire.
5) Couldn't overclock my Q9300 at all on previous mobo, with this one I got it up to 3.69 stable from 2.5. Even with
the exact same components and case throughout. Even then, overclocked, cpu ran cooler than on previous stock mobo.
6) Northbridge is stable with over voltages
7) Onboard audio exceeds desires for everyone but audiophiles.
8) Steady at a FSB that is 2000, that is frekin awesome for a 775 mobo.
9) Lots

Cons: 1) USB 3.0 cuts pci express x16 to x8, however, if you are running crossfire, it doesn't seem to cut into that x8.
2) Runs x8 x8 for crossfire, but not much of a concern, unless you are running something like dual geforce 470's, which would be really weird for a 775 socket mobo.
3)Bios settings have no explanations most of the time, so you have to do your home work or know what you are doing.
4)Bios does not recognize hardware native voltages, timings, frequencies consistently.

Other Thoughts: READ THIS

If you go with this mobo, it really is great, and will only be "doa" if you don't handle bios properly.


Inventory everything you plan on sticking on this, and when you start it, YOU HAVE TO hit the "delete" key for bios and enter everything MANUALLY.

cntrl-i for raid 0,1,5 setup

If you have a soundcard that is better then onboard, then diable azalia codec.

Disable green lan or any green option for that matter.

HPET is only for vista.

MCH voltage = Northbridge voltage

Disable USB 3.0 until you have a crossfire setup.

ALWAYS disable usb 3.0 turbo, the only truly defective thing I found about this board's hardware.

By manually set everything, that also means the advanced ram timings. Check your rams support forums for what are the optimum timings for your ram.
