Did you read the whole guide ??
Are your Ram timings manually set ???
From the Guide :-
First, You need to manually set your memory speed, and CAS timings, and the required memory slot voltage, to your memory manufacturers exact requirements, and regarding the 1T, 2T, setting, for AMD in my experience the 2T setting is more stable, (I suggest 2T to attain your overclock then after you're sure its stable you can set it to 1T and see if your memory will stay stable at that setting). If you leave these settings on Auto the motherboard may fluctuate these settings at the wrong time causing a crash
