I have Gigabyte's P67A-UD7 (upgraded from my P55A-UD7).
The flagship Gigabyte boards are STELLAR
. In my experience, the bios tweaking requires a bit more fine-tuning to achieve stability; that said, a stable Gigabyte overclock is rock-steady. Researching the component selection, engineering choices, and even the single pipe aluminum VRM/chipset/nf200 (though irritatingly impeding the x1 pci-e slot) paints a picture of exemplary development & advancement delivered in a solitary generation of progress.

Regarding the club, after a very frustrating night of very meticulous adjustment, I've managed to accomplish with 1.49 volts dialed into the bios a brilliantly solid 4.9+100.2 bclock. It's so reliable with 1830 MHz RAM i'm paranoid to jinx myself so early in my 2600K experience. Definitely gonna tread carefully before pushing further. Props to those of ya'll who've eclipsed the standard & earned a position in this club, though!
