It is a very detailed guide that had 5 motherboard brands with the necessary settings side by side. Extremely useful to me since it was the first time I had overclocked on a Gigabyte board, I've pretty much always had ASUS in the past.
Overclock.net has a new sticky up as well.
Also I have to say, the default overclock profiles they have are pretty darn close to what works. I pretty much settled on the exact voltage offset they had specified for 5.0Ghz. Any less and it was unstable. Was able to bump the uncore up to 4.5Ghz as well. Only up from 4.2, I gave 4.8Ghz and 5.0Ghz a go, but only managed one successful cinebench run. A couple of random crashes later and I backed it off/
