they used to rate my 2.6GHz opteron as 2.6GHz and it failed stuff... they rate it as 3.9now... sdtill a little off from the 5.2GHz of the FX60(which ha fewer coherent links and runs with a lower FSB if anything I have a better than fx 60 proc)
Thing is mines only an AMD X2 3800+ So as you have a better one than i do i wonder why mine says its rated at over 5GHz while yours isn't.
the opterons don't have a PR rating like the others. essentially they are forced to bull---- the answer. And they do a crappy job.
