5 out of 5 eggsBasementalism

Pros: This motherboard has everything you want for a budget. Seems to overclock very well and runs strong!

Cons: The only complaint i had was when trying to install windows 7 after initial boot i got several file not found error codes from windows. Got through those and it hasnt had any issues at all.

Other Thoughts: Read the specs. I used 1333 ddr3 not 1600 like a bunch of these people. Its not even a gimp that gives you a 7.5 on windows experience which isnt bad at all! I did some research and F3 seems to be the best bios for this right now and you CAN flash it from a usb not just a floppy like some reviewers say. Overall this mobo is an extremely good value despite the mediocore reviews. If you are tech savy enough to read the specs and know how to flash the bios this mobo is a good performer and a good price!

1 out of 5 eggsWhat gabage this mobo is

Pros: for me no pros what so even till it gets fixed!

Cons: I put this motherboard with my i5-750 and 4 gigs of G.skill ddr3 1333 and everything started just fine.Got it to post and boot up and install windows but 1st problem was my g15 to work but couldn't find the setting to have it to start when trying to boot from cd.and second problem is that the cpu is badly down clocked and wont go to the clock it is supposed when its out of game or in game to be at when the speed steeping and ce1 and eist is disabled/enabled and even Hpet

Other Thoughts: if this issue isn't solved by the time I get my tax rebate I am going with another company and never will by from gigabyte again.oh and I did updated the bios to f4 and still same thing.

1 out of 5 eggsPiece

Pros: Non.

Cons: I have built several computers over the years, and i have not seen such a bug ridden mother board in my life. It is auto turbo clocked from the beginning, and the bios are very hard to navigate. I tried installing windows 7 several times, and each time i recieved a different problem. NTLDR.dll did not load, BSOD, and several different errors that just made this board a pain in the you know what. Its kind of bizarre that this came from a trusted name such as gigabyte. Im going to RMA, and i suggest other people take my advice, and dont purchase this awful mother board.

4 out of 5 eggsExcellent Board for the Money

Pros: This board has all the usual features you will need and it's a proven overclock board..unlike other's that are out there Asus and Gigabyte are the ones to buy for I5-750.
Excellent features, nice audio, plenty of usb ports, all around worth the 100.00

Cons: Con's, loses a star for Bios, came with F1 Bios, there's a new F4 Bios but don't use either one. it underclocks your I5-750 or should say overclocks the default CPU speed to 2.8 and locks it there..Turboboost will not work. Turboboost should go up to 3.2 ghz with a 24x multi. it does not. Only works with F3 if you stuck at wondering why, i found out. F3 bios. don't need floppy so dont' listen to other reviewer. obviously doesn't know how to operate or install a bios. so don't worry about that. Again F3 Bios only for now..till they fix the F4 issue

Other Thoughts: Runs excellent as i said,
I5-750 had it overclock to 3.8ghz no problem, but not worth the speed increase, the chip is fast enough, nice to know that i can if i want,
Running with
corsair xm3 4gb @1333
1tb Western Digital
GTS250 1GB
Nice board, get will like it

3 out of 5 eggsI'm not sure yet

Pros: Definitely not the overclocking features(read cons)
Didn't catch on fire(like my first MSI P55-GD55 did)

Cons: I haven't actually checked the BIOS to make sure all the RAM speeds and voltages and everything else are correct. BUT, when you use this boards QuickBoost "feature" that is supposed to overclock your CPU at the push of a button (seems like an awesome feature, by the way) IT DOESN'T WORK. The reason I kept this board rather than an MSI P55-GD55 was because this one would not only cost me money to return to the store I bought it at, but claimed to have OC'ing capabilities close to that of the MSI board (they have OC Genie, which overclocks the CPU at the push of a button). No matter which setting I chose, I could check CPUID and BIOS and it was always at the stock 2.8Ghz. Talk about a bummer. Now I've got to stop being a n00b and figure out how to safely overclock the CPU the old fashioned way.

Other Thoughts: If you're looking for sweet overclocking features, I suggest you go MSI. A friend of mine has his i7-860 OC'd to 4 gigs on an MSI board. I'm actually going to put my P55-GD55 in my rig and see how it works out. Maybe I'm not keeping this motherboard after all..

IN WIN Maelstrom

This board w/ Intel Core i7-860
4 gigs G.SKILL Ripjaws Series PC3 12800
Zalman CNPS9900A Led heatsink
Corsair 750W PSU

Should you be interested in a rig like this, I took the front intake fan that came wit the case, switched it to make it the 2nd top exhaust fan, and added an Antec TwoCool Blue LED fan as the front intake, and my CPU idles in the high teens-low 20C. Hardly ever breaks 30C. It also helps that its probably only 60F down here in my basement.

5 out of 5 eggsIt's a Gigabyte....Buy It.

Pros: Priced on the low end of an LGA 1156 board, however has a little bit of everything one could expect. The software provided is excellent and without reading anything, was able to attach, plug-in everything to complete the build...easy. Over Clocking looks to be very easy with this board....Gigabyte. Spent hours comparing boards, went with a cheap priced good name board. Read the spec's this is a good board.

Cons: Auto loaded the drivers and the only thing that did not work was the lan. However did a windows search and it installed it itself using the boards disk.

Other Thoughts: This is my second Gigabyte board. The first one was Top end, this one is on the low end of pricing. My reasoning is to buy a cheap gigabyte board today and upgrade to an expensive gigabyte board in the future...may not need too. This one is a keeper. Using i5 750 chip.

3 out of 5 eggsMedicore

Pros: Easy to get OC'd, i5-750 was at 3.6 ghz with 212+ cooler in first try. Took a bit longer to push it to 4ghz, but temps were too high.

Cons: Claims to have Dual Bios... it doesn't.

Can only update bios from floppy, not from USB... latest bios is 2 megs... will not fit on 1.44 floppy... good job.

Forget the software, installing EasyTune6 did nothing: app installed but running the exe's did zilch, not even an error message. Latest version, just dl'd from Gigbyte's site. Running Windows 7 64 bit.

Other Thoughts: For 100 bucks, not bad, but really it should have the features it claims.. there's no Dual Bios...

Stuck with f1 bios, f4 will not fit on floppy, Windows software will not run... (even if I were to feel brave enough to try Windows bios flash)

5 out of 5 eggsWorks Great

Pros: Booted up first try no problems. Overclocked an i5-750 easily to 4.0Ghz.

Cons: none yet

Other Thoughts: I admit, I was a little hesitant when purchasing this mobo with the mediocre customer reviews that it received here on Newegg. But this board had everything I needed at a good price, plus it has the trustworthy Gigabyte name behind it. So, I decided to test my luck and go with this model and couldn't be happier.

1 out of 5 eggsLow Quality GigaByte, Unlike their better boards

Pros: Lots of SATA connections for an affordable board.
Latest F4 firmware resolves memory compatibility issues.

Cons: F3 BIOS firmware is unstable.
Front Audio panel connection is stupid spot.
Main GPU slot covers first SATA port with medium to long card.
Board is not very wide, doesn't make use of third row stand-offs.
No Firewire.

Failed working after a couple of weeks.

Other Thoughts: At first this bug ridden board seemed pretty decent after working through all its little issues. I had it working great for about a week. Then the disk controllers stopped working properly, started corrupting data, and eventually prevented Windows from booting or installing correctly. Tested extensively to resolve the issue, but couldn't realizing finally that the board became defective.

I bought this based on the fact that it was a Giga-Byte board and that I trusted their name, but their cheap board here just isn't up to the same quality as their higher priced counter parts.

It's being RMA'ed for a refund and being replaced with an ASUS P7P55D.
