Error frequency does not change between copying from a 2400MHz@2.4 > 600Mhz@2.5 and 600Mhz@2.4 > 2400MHz@2.5. IIRC, I had errors from a 200MHz@2.4 to a 1600Mhz@2.5 too.
Even if I run them both against each other, the error only happens on 2.4 and the frequency does not increase. This is not a simple timout problem.
I'll think it through and build some scripts so everone can reproduce it and test it out.
