Pros: I've only had it for It's unanimous, this is a gorgeous board! Very careful details were taken that only builders would enjoy like an attractive glossy push button for the onboard power button instead of the standard simple mechanical switch. And a cap on the firewire header so it doesn't get mistaken for a USB header. USB headers are clearly labeled and onboard power button is located in a much more accessible location than normal. Little details like that. Beautiful glossy coating over everything. I just set it up this morning and everything's working perfectly! Good separation between the NB and top GPU slot. More rear connectors than you can shake a stick at. Tons of storage options with 10 onboard SATA ports, 2 eSATA ports at rear, onboard firewire header, firewire ports at rear, IDE, & floppy. the connectivity is endless! Great BIOS options and a slew of utilities. Looking forward to seeing how this overclocks my Ci7 920 D0. I switched from an evga X58 and I couldn't be happier.

Cons: As it was mentioned before, the IDE and floppy connectors can be hard to get to at the bottom edge but they don't used much anymore anyway. 3-Way SLI seems impossible unless you used single-slot cards (or watercool the bottom card). The bottom slot is the third PCIe GPU slot so if you have a 2-slot cooler it'll hang off the bottom of the board and odds are your case will not have an extra expansion slot for the cooler. My P183 doesn't. With 2 GPU's installed, the SATA ports, POST code LED's, IDE, and Floppy connectors are alomst impossible to access but this will be the case with many X58's using SLI. All my "con"s are fairly minor. I wish they would've just gone for 2-way SLI/CF only and put an extra expansion slot between the GPU's for better cooling but this is how most of the X58's are designed.

Overall Review: I've only had the board for a day but I just hated seeing the only 2 reviews available were both defective 1-egg reviews so i had to post my initial experience. I'll write another review if anything changes with the board. I'm happy to answer any questions about the board if I can. Just email me at bdewitt82 at live dot com.

Pros: This is an update on my initial post from the perspective of 13 month of GA-X58A-UD5 ownership. As noted in my initial review, the GA-X58 board has great features and has not presented with any problems at build time.

Cons: I have dealt with three failed GA-X58-UD5 series board across two systems (two GA-X58-UD5’s and the current GA-X58A-UD5). The boards failed between 13 and 18 months and RMA’s have been per Gigabyte support recommendations (i.e., replacing the motherboards fully resolved the problem). The boards were never over-clocked and environmental conditions are excellent… Technical support has been hit-or-miss by phone and consistently slow and unhelpful by email. On three consecutive occasions, Gigabyte has returned the same respective non-bootable motherboard that I sent to them for warranty replacement. The first two boards were replaced under a second RMA with free shipping but a pattern of immediately returning the first RMA is apparent based on my experiences. I am not certain if returning a clearly defective product is policy, incompetence and/or if Gigabyte is just trying to detour warranty replacements.

Overall Review: I have been a longstanding patron of Gigabyte and I predominately replaced the most recent defective boards with the same model/series based on blind brand loyalty. Regrettably, mindboggling poor warranty support and poor product reliability are forcing me towards other manufacturers. I simply do not have the time and energy to deal with such poor product support. At present, I cannot recommend this board secondary to poor reliability and I will no longer blindly recommend or patronize the Gigabyte brand secondary to poor technical support, and poor and seemingly evasive warranty support.

Pros: Great when it works.

Cons: Non-existent support. This is what originally happened: So, I owned this board for 6 months almost to the day before it crapped out. Began with blue-screens and then went to a verifying DMI pool hang. After following all troubleshooting and forum help it was determined there was a fault in the board itself. After double testing all my ram, g-card, HDs etc in another system I was 100% sure it was the motherboard. After putting in the RMA on January 20th and I received absolutely no response. Even after the 16 calls, 8 messages and 10 emails I sent to the company to follow up. On february 8th after I posted a bad review here on newegg I finally got a response through a comment response. I sent in my card and waited for 2 weeks for them to send it back to me. I received it today, and you wont believe what happened.

Overall Review: They did not even open the anti static bag that I sent the board in! They literally took it out of the box I sent it to them in, put it in another box, and sent it right back to me! How do I know? I put a label to seal the bag which you have to tear to open the bag, this wasn't torn, hell it wasn't even wrinkled! I also used an aftermarket bag which was too large for the board, I put an extra fold in the side so it would be snug and taped it with another DIFFERENT label. In order to remove the board you would need to remove the label, this label was not moved. The same DMI pool hang is there, and now it wont even recognize the graphics card (which has been tested and works) Run from this company, they are shisty, their products are poor quality and do not follow through on their warranties.

Pros: Like I said in my first review, its a beautiful board. The components are 1st class, better than the ASUS P6X58D. The large power button on the motherboard and the Reset CMOS button on the back of the motherboard are very handy for overclockers. The heat sinks and heat pipes are also much better than the ones found on the ASUS P6X58D.

Cons: The board layout is poor due to the PCI-E spacing. You will not have enough space to run two video cards with a PCI card. I wanted to use two video cards with a PCI TV Tuner card but there is not enough space. I could not get the board to boot until I flashed to Beta Bios F2 and changed out the Nvidia video card to an ATI card. Yes, I tested the Nvidia card to make sure that it was working properly. To be fair I have had this problem with Nvidia video cards in ASUS boards to.

Overall Review: This board is easy to work with due to the Power button and CMOS Reset button on the board. However, I have not been able to overclock my I7 920 DO more than I was able to on my original UD3R nor the ASUS P6X58D. If you compare the ASUS p6X58D vs the Gigabyte X58A UD5 it is not worth paying $40 more for the ASUS. Gigabyte seems to be making better quality boards then ASUS has since the P35 line of boards. ASUS releases BIOS updates faster than Gigabyte.

Pros: The board has a ton of USB and SATA ports. So if you think that you want to use the 6GB SATA controller or the Inte ICH10R, you'll have plenty of options. Overal the board supports all of the i7 first generation CPUs without issue (including 6 cores), and does will with DDR3 triple channel RAM. Frankly, with the top of the line parts installed (video card, CPU, RAM)... that latest Intel CPUs barely edge this rig out, and often are not faster.

Cons: The biggest issue I've had is that the board WILL NOT allow you to boot from an ADD-IN HOST ADAPTER (such as a 3Ware 9650 or an LSI 9750). If you install an SSD to use for a page file (swap space) and attach it to the Intel ICH10R, forget booting from a "SCSI" device. Additional, performance testing shows that the board's 6GB SATA controller is really not very good compared to either the Intel controller, or, especially add-in adapters, such as the 3ware/LSI units. In fact it's basically a waste to use it if you want perforance.

Overall Review: My configuration is: 1 x 3Ware 9650 SATA controller w/ 2 300GB Velociraptors, 1 x LSI 9750 SATA controller w/ 2 600GB velociraptors, 6 x 4GB Corsair DDR XMS3 RAM, i7-980X CPU (32nm, 6 cores), ATI HD 5870. What I've noticed is that the add-in RAID controllers pretty much destroy most of the SSDs I've tried with the velociraptors in RAID 0. The on-boad RAID does not come close in performance, as it's got no cache RAM. The Intel ICH10R with an Intel 120GB X-25M SSD operateds at about 175MB/sec, which is good, but not incredible, and not overall faster than the RAID 0 velociraptors.

Pros: Great Board. SATA 3 , USB 3.0, 2 Lan Ports Works great for hackintosh, linux, Win 7 (Yeah triple booting)!! Clear CMOS button on the back in case you really screw something up on settings. LCD display of current state for troubleshooting

Cons: Shares USB and eSATA Ports, so if you want to use eSATA you lose a USB. Is it too much trouble to keep them seperate?? well at least they give them to you. USB3 not recognized in MACOSX neither is SATA 3, but this isn't a problem with the board, but MAC OS. Heatsinks around the processor made me a little nervous that my cpu cooler wasn't going to fit, it did.

Overall Review: Big CPU Cooler like the Thermaltake one doesn't work with super tall memory, not really a con of the motherboard, but just wanted to mention it so that your aware if you get it, I had to put the CPU fan in more a pull than a push arrangment, doesn't work as good but gives room for up to 6 sticks of the tall ram. Pretty Lights. Flash your bios before doing your build, save you some heartache possibly later ( this is just smart practice) Can flash from a USB stick!! I swore up and down after my other Gigabyte board (Nvidia 680i), I would not buy another one, but this one was too tempting. So far not regretting it.

Pros: Bought this as a combo with my i7-920 and couldn't be happier! Plugged in everything and booted right up. Overclocking was very simple even for my first time. Just had to make sure to read as much as possible so I wouldn't mess anything up. Have not tried to SLI or use the 6Gb/s sata but will some day.

Cons: Like others have said the pata and floppy connectors are hard to get to but I use neither so it's not a problem. Also, the USB was a stretch and had to do some crazy rerouting in order to get the case USB plugged in. I have not tried to SLI but my EVGA GTX 275 seems rather close to the next PCI-e x16 slot, I'll cross that road when it comes though.

Overall Review: Gigabyte has never disappointed me and I recommend it to everyone I know.

Pros: What a beautiful motherboard, it has all the bell and whistles to justify the cost. Pros= SATA3.0 USB3.0,2x copper (heavy board),LED status lights, LGA1366. I read those reviews before mine and I still bought this MB because it has everything for now and the future. I read the manual, put everything where it belong and it boot first try no problems. : )

Cons: The other reviewers that have problems, It could be how you slot the triple channel memory wrong or how you connected the hard drive. well good luck to you all

Overall Review: I feel out of all the 1366 I7 slot Motherboard this one stands out. I been waiting years to upgrade and this past week I finally did 200GB 10K RPM HD 1GB 5870 6GB DD3 1366 I7 940
