5 out of 5 eggsNice little motherboard

Pros: AM3 and AM3+ socket which makes it still up to date with AMD technology.
Plenty of USB ports.
Decent enough onboard sound for the price.
Plenty of SATA ports.
USB 3.0.
3 PCI Express ports.

Cons: No Parallel port, but that is dead technology anyway.
6 Sata ports I quickly used up since this is my main build, but it is easy to add a controller card and 6 is the standard in most desktop motherboards.

Other Thoughts: Still going strong after 3 years. It is my primary gaming machine motherboard and it can handle everything from AM3+ to SLI and Crossfire.

5 out of 5 eggsBeen working since 2011

Pros: I don't even want to start because at the end of the day it's just a motherboard that did exactly what i wanted it to do and is very reliable. I purchased it in 2011 and it is now 2014 and is working flawlessly.

Cons: - Not enough fan headers

- Only one PCI-E X16 (X16, X8, X4) that only matters if you are using Crossfire but even then it's not that big of a deal.

- The looks might be a con. It depends on your taste.

- I originally had a Phenom X6 1055T @4.0Ghz and when i swapped to my FX-8320 the bios update went fine and everything but when i put in the FX-8320 it would boot but i got no display. After a LOT of troubleshooting i put back in my old Phenom and went into the bios and set "Load as Fail-safe defaults". Before i clicked "load optimized defaults") to reset the OC on my X6 before swapping. That is literally the only problem i've ever had with this mobo.


Other Thoughts: I don't even think this motherboard is available to buy anyone but i feel i should do the justice of writing it a good review since it's been good to me.

If you are looking for a AM3+ motherboard pickup the Gigabyte 990FXA-UD5. It addressed both of my cons, It's black and looks great and has two PCI-E X16 lanes in case you want to do crossfire. It's also priced about $20 higher than what i paid for this but it's definitely worth it.

1 out of 5 eggsSomehow worse than garbage

Pros: Looks great.
Apparently has good features?

Cons: Installed 3 graphics cards, refuses to make it past the Windows 7 boot screen.

Updated BIOS, no revision of which does anything.

2nd Gigabyte motherboard that fails to support even the most basic of hardware, I even switched from Intel to AMD!

Currently waiting on the RMA of my first board, clearly Gigabyte does not care about their customers or they would make products that would function properly.

Nothing short of a brand new motherboard; that functions as it is advertised, free of any kind of charges (shipping or otherwise), would suffice to make this right.

Other Thoughts: Buy a motherboard from ANY OTHER manufacturer.
Stay away from Gigabyte branded ANYTHING.

They are in the business of peddling broken items, which they then make you pay to replace!

5 out of 5 eggsGreat Mobo

Pros: The backup bios and how easy it is to update the bios is great. On-board tweaking is quite easy too.

Cons: I have yet to notice any throughout my time having this.

Other Thoughts: though it has 3 pcie's they are spaced so that only two are for gfx cards but i use 2 cards and the third for my SSD awesome performance that way still.

Pros: It was fine till it stopped working.

Cons: I started to get random bluescreens after 6 months. At first I thought it was my RAM or my video card, but that wasn't the case.

2 out of 5 eggs poor support from gigabyte

Pros: Fine while it worked...

Cons: Had this mobo for not even a year and diagnosed down to a bad dimm 1 slot. Emailed gigabyte with my findings and this was their reply:
Gigabyte: Dear Cody martin,

Thank you for your kindly mail and inquiry. Because there are too many kinds of memory modules available in the retail market, it is very difficult to test all of the modules with our MB products.

Thus, if possible, we suggest you can test your system with other memory, or the memory listed on the memory support list from our website to see if there's a memory or motherboard problem, for memory support list, please click HERE.

But, if the problem still occurs with other or supported memory, then a further testing or examination to your system might be required. We suggest you to contact your motherboard supplier or nearest distributor and see if they help you to test your system directly.
I have since bought an msi gd80v2 and ram problem solved.

Other Thoughts: Waiting on their reply if they will offer some sort of compensation for their faulty mobo.

4 out of 5 eggsGood Board, but Fear the Rev 1.0's

Pros: -Good Board, Paired with my PII X6, it was unstoppable for two years, until... (See cons and other thoughts)
-Good Price for what it can do
-Many USB ports, including 3.0
-Nice BIOS setup, easy and quick to OC anything
-Q-Flash is amazing for BIOS updating, quick and painless
-Still going strong after 2 years
-Sexy blue design

Cons: -Rev 1.0 boards do NOT have LLC, which can make OC'ing and running come CPU's impossible to do without the dreaded V-Droop, and can cause instability
-Personal Quirk, but those SATA connectors are an annoyance
-Some of the FAN pins are in really inconvenient places
-The back pannel didn't match up with the mobo, cutting off the USB slots, and forcing me to cut it in places to compensate (prob an issue with mine, no biggie)
-The LAN driver needed to be installed, so new installations of windows needs to have the driver on hand before the internet will work
-Another personal quirk, so it won't take points off, but the other 1x slot gets cut-off with my 580 installed. This is bad because I use two 1x capture cards, and one of them is forced into the bottom PCI slot because. Which leads into...
-Bad SLI design, if you plug ANYTHING into the PCI X16 slot under the top one, it makes both run at PCI X8. I didn't know about this until I read about it on their website, since they mention it NOWHERE ELSE, and immediately switched it into the bottom slot, which fixed it. I understand design and limitations, but a friggen' warning would've been nice, besides the fine print on a page that I didn't even see for the first two years.

Other Thoughts: Story time, so brace for paragraphs. I do apologize for this.

I originally got this Board because my Previous board wasn't compatible with the then brand-new and amazing Phenom II X6. It ran perfectly with NO issue for two years, until I decided it was time to learn how to overclock. To my surprise, despite the reviews raving the easy overclock, I was finding difficulties getting a stable clock above 3.5Ghz. Bluescreens, blackscreens, you name it. I thought it was my inexperience and passed it off, until I finally decided it was time to upgrade to the FX-8350, something I needed for my internet gaming show (since streaming takes up so much CPU power). I didn't have the cash to make the switch over to a big intel, so I just up and purchased the FX chip, since my MOBO was compatible, and flashed the BIOS with the compatibility update.
When the FX chip got here, I tried it in the unit, and lo and behold, it worked. However, a few days into owning the new unit, something started to happen, under a lot of stress, the PC would just up and blackscreen into oblivion, then restart. This killed my server that I was running, and made my bad pretty sour. I then started running stress tests, and it was blackscreening pretty consistently, almost guaranteed. This was at default setting, stock everything. I read up and found out that the Revision 1.0 boards, which I had, didn't come with Load-Line-Control (LLC), and as a result would cause V-Droop during stress, which can cause a blackscreen. I tried to overvolt, but nothing, the V-Droop was too much and my PC was just unusable as a result. I tried all of the methods to fix the issue I could find online, but the only thing that saved me was underclocking it to 3.4Ghz, at 1.3V. It's barley more powerful than my X6, but it'll have to do.

I already bought a new MOBO, one that's built for the Piledriver, but I'd thought I'd share this little story, as an learning lesson to anyone that has any similar issues. It's always best to research these things, or else they'll come back to haunt you.

1 out of 5 eggsNope nope

Pros: Worked great for a good 10 months or so, easy to setup no problems for that time anyway.

Cons: Not too long ago I started getting lots of random blue screens. Then I couldn't start windows at all. Couldn't re-install windows and now can't even access BIOS. After extensive testing it cam down to the board itself. I was on the phone with Gigabyte tech support for awhile and they didn't seem to want to believe that anything was wrong with it. "Well you can send it in and we'll test it if you want, but I don't think anything is wrong with it. " It came back today after being gone for 2 weeks and it doesn't seem like they did anything to it. No notification of any testing or repair and I'm still having the same errors that I had before but now I can't even access the BIOS. I'm sure I can call them back tomorrow and have it sent back in, but that'll be another amount of $ that I'll have to pony up to send in on my own that may or may not fix anything in the first place, just like last time.
