wait wait wait, seems that this motherfucker just hate cold, at "single stage" max out at 5465 MHz, at air it boots at 5500+ MHz.
i gotta find a way to keep it around -20° C and see what happen.
i'm not against memory benchmarks, i'm against bugged benchmarks like this one is
and BTW, when you said "i can beat your score with CPU 100 MHz lower than you" you automatically assumed that CPU frequency have some kind of impact on the final score.
