This motherboard is unable to sustain an overclock without throttling after a few seconds. This totally defeats the purpose of buying a Z68 motherboard. Any H67 mitx motherboard is cheaper and likely more stable than this mediocre motherboard with terrible bios. If you want a sff Z68 motherboard that overclocks then your only option is a good Asus, MSI or Gigabyte matx motherboard. I really like the Asus Maximus IV Gene-Z, It's a rock solid board that oc's like a champ.
