It is running at 5.1, and I just proved it isn't throttling. It just doesn't score as well as my regular 8370.
There's absolutely no reason that it would have such a big difference in score,after all it's the same architecture with same number of cores.It probably is throttling or not sustaining the clocks well and hence The Stilt is right.It just isn't running at 5.1 for the whole period.
Also the 55C temperature at 5.1GHz with Wraith just can't be of a sustained clock,no point in reporting such temperatures.
