It works perfectly well, but like all models of this series from Gigabyte, there sometimes has the bug of "boot loop" = during a cold start after a few hours / days of non-use, the PC will sometimes restart loop 5-6 times (it goes off altogether, restarts etc.) before finally start ...
Solutions exist but they are complex to implement for the "non-yourselfer".
For the geeks: It seems that there is a concern under voltage RAM / her sometimes when the controller bootloop, and sometimes recovery backup BIOS etc .... I put (!) months to understand that this was not a concern related to overclock etc; there VERY MANY topics related to this specific concern with the Gigabyte Z77 chipset (and perhaps Z79) and the only solution I have found after many hours of research / reading, is to go through a modded BIOS and it is necessary to increase the voltage of the RAM (1.6 ... even 1.65v on the non overclocked RAM @ 1.5v), and the memory controller, so sometimes quite pronounced. The bug is random, it takes quite some time to get to know if the machine is finally stabilized. I would add that if like me you have a server with 8 connected disks, 5-6 cycles of ignitions / brutal extinctions is REALLY NOT acceptable .....
I conclude by saying that Gigabyte is a brand that I really like, I set up half a dozen PC motherboards with this brand, I bought personally from without problems, but on this series, although now I have a stable PC and I know why I had these worries, it is a pity that Gigabyte has not provided or found a solution, despite the many calls for help from users on the Web ....
CONCLUSION:
-> If you are not computer handyman, I do not recommend the series Z77 / Z79 of this brand, due POSSIBLE bug "loop start" and you will find your happiness equivalent from ASUS / ASROCK / MSI / .. ..
-> If you are geek and ready to settle the concern of bootloop if you are unfortunate enough to have it, it's a great addition for motherboard, perfectly stable, I am typing this comment on while the machine encodes the video, and 1TB of data during disk to disk copy on a core i5 2500K overclocked to 4.7 Ghz.
