Another problem is that BIOS update won't work. I tried to update and it was stuck at 0%, I had to shut down the computer. Fortunately, it was still working just fine. Apparently, other users have the same problem.
Most settings changed in this guide will resemble settings on your board even though Der8auerr was using a board from ASUS.
Also, unless you're trying to squeeze every last drop out of your processor all you virtually need to change is "Load Line Calibration" to one of the highest settings, though not the actual highest, set your desired frequency (i.e 4800MHz) and change your vcore (i.e 1.33v) until it is stable.
