Use Intel Burn Test to test load.
Mine also runs great at 4.2 but I had to increase voltage past 1.35 in order to go above 4.4. At 4ghz (200x20) it only uses 1.1v but does not feel as fast as 190x22. However, this CPU loves 4ghz to 4.2 at low voltages using all 6 cores and all 12 threads. I can't believe how much more Folding it does over my 930 at the same clocks. I'm only running 190x22 and its nothing short of a new computer. Feels no different then my Dads X79 i7-3930K, but he spent MUCH MUCH more then I did, haha. In fact, since he is not overclocking his Sandy chip I suspect my 4.2ghz Westmere is faster. Both Windows and Linux are noticeably snappier, and games run much smoother.
Best CPU upgrade to date.
