The Intel socket LGA2011 motherboards have not been out for real long, and if you picked one up to try out the Sandy Bridge-E CPUs, you may be running a Gigabyte motherboard. The problem with that, is Gigabyte has issued a recall notice for three of its LGA2011 motherboards: the GA-X79-UD3, GA-X79-UD5, and G1.Assassin 2 X79. All three motherboards' VRM cannot keep up with the stresses of overclocking, and even a fairly mild overclock can cause the VRMs to go up in a puff of smoke. The issue could relate to bad firmware or just bad VRMs in general. Gigabyte has issued a BIOS update that will throttle the CPU under extreme stress, which elimnates overclocking basically, or you can send the motherboard in to get a replacement once a fix is available. You can send in motherboards that have already suffered from the problem or perfectly functioning ones, but your free replacement will not arrive until there is a fix. Gigabyte will also pull all afflicted motherboards from retail outlets until there is a fix, likely putting a small dent in overall sales until then.
