4 out of 5 eggsupdate

Pros: Not sure why my name is showing up as NA, like not sure from idiocracy? anyway to update my original post gigabyte called me next business day, offering to help offer support and ask for more details on what was wrong. AWESOME!!! I originally setup hackintosh, the board came with BIOS f7 on it. Hackintosh worked except i never got sound at all and usb was quirky (the usb device would work as long as it was plugged in prior to boot, otherwise it would crashs sytem) and I had random powering issues with it. so i used it with 16 gig sandy i7 quad core to save me 6000$ from Apple and rendered like a beast while at home from work. finally i had it and built a new hackintosh and installed 7 ultimate on this and at first ... you get my first post about restarting issues and random shutting down issues. after a few updates and such - it is working GREAT! for the past week.

Cons: After ultimate 7 install i installed DVD drivers that came with the board.. as any expert knows... not always to be trusted. the power / energy saver crashed the system (even more random shutdowsn and restarts) I installed some other software from the dvd(same issue) so I uninstalled the software from the dvd - installed only the required drivers for network and chipset and ran all windows updates. had one or two issues wthile running steam Black OPSII i hit esc to pause went to pick up my wife from the train station came back to my UPS with a consistent beep and the system shutdown. had to power off my UPS my system and restart???? that is when i wrote my first review.

Other Thoughts: It has been 1 week since my initial review and my system has been running like a champ, so what changed? not sure(idiocracy) the only change was I ran the video card update from Steam for my Radeon 6800 series card since then not an issue or power flux. SOOOOO be aware that there is some sort of PCIE issue potential with motherboards, ... add it to potential ram issues and potential PowerSupply issues. this one though strictly Video Card or so far it seems Gigabyte still rocks for the professional looking for top notch ... on a side note, what notice will you see between 3.9 quad core and 4.6 quad core over clocked? 2 things one nothing and two your overclocked will die needlessly sooner. If you wnat a faster system... BUY A FASTER SYSTEM

2 out of 5 eggsFinally got around to trying to use this

Pros: Bought for recommend Hackintosh, had boot issues from the beginning, tried a different power supply, but still same issues. the sytem ran great when it did post and load os. very fast, very very fast.

Cons: when it did post! it would sometimes just power off during post and forget restarting it just shuts down all together. It does load 1 in three boot attempts. and will stay running as well it it seems fine, but have only had windows 7 ultimate installed for a few hours,

Other Thoughts: Gigabyte seems to be so close and very possibly capable of making some great boards, not sure what it is, but just make it work. they seem to be slacking lately hope my latest z77x-up5th runs osx better multi-beast here i come

4 out of 5 eggsUPDATE

Pros: The board is tough and can take a beating. I have experimented with several different setups and overclocks and this board has handled it like Ali handled Foreman back in '74 in Zaire (this board rope-a-doped my efforts to overclock the CPU). I cannot believe how tough this board is. There were a couple of scary times but I was able to press and hold down the power button to start the PC and then have it shutdown and restart again to force the backup BIOS to kick in.

I also discovered the ALT+F12 method to overwrite the backup BIOS with what is in the main BIOS. This helps me keep the backup BIOS up-to-date with the latest stable version of the BIOS. I hate having the backup BIOS rewrite the main BIOS with an older version of the BIOS.

One of the cons from my previous review actually turned into a pro. This involves my madman rant about the orientation of the SATA ports and how all the board manufacturers should orient the ports orthogonally with the board like they used to...well, I take that back. I see clearly now that this orientation of stacking them and making them parallel to the board is beneficial for slightly better cable management and slight better airflow.

Cons: The other two cons from my previous review still remain and a new con surfaced:

1 - You will lose a PCI-E x1 slot and a PCI slot when running SLI or CrossFireX. This forced me to install my sound card into the other PCI slot and caused poor airflow to my top GPU. I rectified this problem by getting an updated sound card that was PCI-E x1 but I had to install it into the bottom PCI-E x4 slot which then left me the same problem of poor airflow to a GPU, this time with the bottom GPU. This leads me to the second con.

2 - The top PCI-E x1 slot is completely useless unless running a wi-fi card. This is because the heatsink that covers the PCI-E lane switching controller is too tall and is directly behind the said PCI-E x1 slot.

3 - The CPU power connection is still a pain in tight areas.

Other Thoughts: Still a great board with many features at-that-time.

4 out of 5 eggsGood But Not Great

Pros: 1.) Board has excellent features.
2.) This board makes overclocking easy and there are a lot of options in the BIOS.
3.) The quality of parts used is excellent considering that I've tried so many setups with the rig that I thought I may have destroyed the board.
4.) Board is cool even under overclock.
5.) Many ports - I use many external devices and the hybrid usb/eSATA is convenient.
6.) The reset and clear CMOS buttons are convenient (especially for my extreme overclocking tendencies). Many times I thought "I'm pushing it too far and I'm going to pay the price for it." However, the board just keeps working and the reset switch has bailed me out when the board wouldn't post.
7.) One option under memory voltage allows for you to drop voltage to something ridiculously low and this allowed me to buy another 16 GB of 4x4 PC12800 DDR3 RAM that operates at 1.35 volts to actually run at 1.35 volts instead of 1.45 or higher as with many other boards. This has helped me overclock more n

Cons: 1.) The poor orientation of the SATA ports - you will understand if you've worked on any z68 chipset board. I do not know why Gigabyte AND other manufacturers are doing this. There is plenty of surface area to fit traditional SATA ports that are orthogonal to the surface. This trend with "stacking" SATA ports and facing them sideways (parallel to surface) is unsatisfactory. Gigabyte is not the only one to blame as I've worked with other boards from different manufacturers that do this as well.
2.) The CPU power connection is too close to the large Northbridge heatsink and makes plugging into it a pain IF you are working in a small volume of space.
3.) If you are running a dual-graphics card setup, you WILL lose access to one of the PCI slots and you might be able to squeeze a skinny PCI card in the other. I was barely able to squeeze my sound card in there. You will also lose access to one of the PCI-Express slots (x1 lane) with any of the newer cards (that cover up slots).

Other Thoughts: 1.) I did not have any alignment problems with the input/output template as others have noted. Maybe I got lucky.
2.) There are better boards for the price when it comes to overclocking; however, I am satisfied with paying the $200+ for this board considering it has many features of a $300 board. I have used a Zalman fan+heatsink and a Corsair H100 liquid cooling kit with very good results. With good parts, I was able to hit 50x multiplier on air and 51x with liquid on my Intel 2600k. I've read sites that have talked about being able to top out at 47 multiplier for this board with good cooling on the 2600k but I've managed higher and, don't know what the sites were doing...unless I just happened to get really lucky on cpu and board and methinks that is a low probabibility.
3.) No Quick Sync - but if you are interested in a board like this, you are probably going high end discrete graphics anyways.
4.) This board+2600k cpu+16 GB RAM+SSD+460 GTX SLI = getting anything done

2 out of 5 eggsGave Up

Pros: When it work it OC's very well.

Cons: The constant resetting coming out of sleep mode has finally made me give up on this thing. It would run fine for a few weeks then when you tried to come out of sleep it would do the constant reset.

Other Thoughts: This was my first Gigabyte MB. I had used Intel 100% before with no problems. I needed OC ability this time.
Going to try Asrock now.

4 out of 5 eggsGood, but not great

Pros: Black, all of it. Looks exceptional and functions great. Plenty of I/O connections to hook up a multitude of internal and external devices.

Cons: Only a couple of SATA III ports, would like to see more especially to go with the premium price tag. Standard outdated BIOS is kind of sad to see especially with all the other boards out there with UEFI, cost less and overclock better.

Other Thoughts: This board functions well, but unfortunately Gigabyte did not hook us up with the new BIOS and it gets old having to switch through a multitude of areas to adjust settings that could easily be placed in the same areas. Overall it's a good motherboard, but I would rather have an ASUS.

5 out of 5 eggsWorks great!

Pros: Very well built, everything works out of box.
Great for Overclocking.
Plenty of expansion slots.
Not a bad price for a motherboard like this.

Cons: None that I can think of.

Other Thoughts: The Rear IO ports do not line up perfectly with the rear io shied, but this is not a major issue, all the pugs still fit into the ports.

1 out of 5 eggsDead on delivery

Pros: Can't think of any

Cons: Received it dead on delivery. Communicated with Gigabyte, they suggested sending it back. Received an RMA and sent it back to newegg, ordering identical one at the same time. Received a new one, which works great so far. However, RMA has been rejected for a broken pin reason. First of all, I have been doing this since my first build in 1993 numerous times. Second, newegg has no proof that I have broken the pin. Third, same CPU works fine on another mobo. I am very frustrated by this: am never going to shop newegg again.

2 out of 5 eggsUpdating my last post ...

Pros: 1 of 3 boards is working like a champ.

Cons: So, I replaced this board through RMA ... thanks NewEgg!

No joy on the board only recognizing 12 of 16 GB of Corsair Vengeance RAM. Researched on Google, looked like a possible BIOS issue. Updated to F8, no joy.

Bought 16GB of new Corsair Vengeance RAM. No joy.

Discovered Corsair Vengance RAM (4GB sticks) is not on the approved list from Gigabyte. Bought 16GB of Kingston 4GB RAM from the approved list and the same issue persists. NO JOY!

More Google research indicates that this is a known issue. As a reminder, when I add the 4th 4GB stick, the mobo goes into an endless boot cycle and never posts. This is exactly the
same behavior the original RMA-ed board had.

Making this more frustrating, I have an IDENTICAL machine sitting next to this one which is running 16GB of Corsair Vengance without any issue. Research indicates that it is the exception, not the norm.

Other Thoughts: This is an update to my review on 08/12/11. If Gigabyte support is listening and want to ping me for some hand-holding, I would love to hear from them. I've tried everything I know to resolve it short of RMA-ing a second time.

I want be a happy Gigabyte owner.

3 out of 5 eggsMemory Issues

Pros: Solid board with lots of great features at a reasonable price. I own two.

Cons: As mentioned by another user, it has issues with newer ram. I am using 16GB of Corsair Vengance. I have bios updated to F7. On one machine, no issues. On the other, I cannot get it to play nice with more than 8GB of ram. It goes into an endless boot cycle. I RMA-ed one board thinking the board was the issue. NOPE. I ordered new RAM. NOPE. Looks like the issue is with the board and there is no resolution in site.

Other Thoughts: I really like Gigabyte tech. And, after Googling, it looks like this might be an issue with the Intel chipset and not the board. Either way, it is frustrating.
