not bad tests, but it would be nice to check how it behaves at a voltage of 0.95v. I dare to assume that the optimal operating mode will be achieved at this voltage.
Man you core voltage critical 1.644v !!! Max 1.55v in air cooling. And ours motherboards low VRM 4+1 phase for overclock too bad :(
ps: my system working stable at 4.0Ghz(see profile). and normaly working 4.5Ghz, but linx bench or render video - freze 3-5mins.
