that's true, I got to 3.7GHz with my E6600 with no trouble, but getting it to do 3.83GHz orthos stable is taking me days, and it's so inconsistent, same settings sometimes give me almost 5hrs orthos and sometimes it blocks after 17-20min, strange

that throttling is (probably) caused by the power management ICs being @ 33C or more, but keeping it under that temp doesn't. Despite that you can handle it by installing the Rightmark cpu clock utility and turning off anything that has to do with EIST (CPU advanced settings tab -> untick everything), the problem with this board is that there is no BIOS option for turning it off, can't do it any other way except with this program.
