    even so those are some crazy high idle temps, mine is @ 3.1 right now and idles @ around 38° which is high imo load is about 58° and your core voltage is pretty high and so is your vid might just be a sour chip i have found that 1.375 is the sweetspot as far as voltage is concerned for my chip you might try to reseat your hsf and check your air flow?

    Maybe your CPU HSF isn't mounted properly? If it is, you should consider some aftermarket cooling.

    From the information currently available, I'd take a guess and say running your memory out of spec is what's making the PC fail to POST at times.
