UD5 is a big no for higher oc. Max cpu voltage in bios = ~1.8V what gives ~1.65-1.7V under light load but board has problems to boot at this voltage. When we set ~1.7V we can get 1.65V idle and ~1.55V under load what is about ok to make 5GHz even without LLC. For that you need really good water cooling but it's possible. Anyway any sub zero cooling seems waste of time on this board.
I also have some problems with memory settings. I can't make 250+ FSB with high memory clock. In any config I end up on ~2300-2400 memory, no matter how high is CPU-NB or voltages. I doubt that's my memory problem as I can boot @2300 cl7 but I can't pass 2400 cl10/11. The same on 3 kits , all on PSC ( so like 10 sticks ). Max stable FSB ~300-305MHz but with memory no more than 1800.
I can make it stable @4.5GHz at least for F@H or anything else that I'm using so it's just right for me for 24/7.
