Pushing your PC to its limits has obvious inherent dangers; overclocking your CPU can definitely bust your rig if you push it too far. That being said, reasonable overclocking doesn’t actually carry too much risk – normally. Right before Christmas, one overclocker’s Gigabyte GA-X79-UD3 mobo crashed, then burned (literally) in the midst of a lightweight stress test. After he posted the video on YouTube, Gigabyte looked into the problem, and apparently, it wasn’t a case of crap luck. Yesterday, Gigabyte’s Chinese branch announced the faulty CPU VRM is a widespread issue and recalled all GA-X79-UD3, GA-X79-UD5, GA-X79-UD7 and G1.Assassin 2 mobos. US users, meanwhile, get a critical BIOS update.
