So, if it's prime as you say, why does it happen with my B3, and when I pop in my G0, without touching bios, it does not? If it was setting-related, or prime(software), then changing cpu should have no effect, no?

Why does it not happen with my B3 but it happens on my C0? I think the bigger question is why does it only happen on prime SFFTs and not blend, OCCT, cinebench, or video encoding? Why does the x64 version do SFFTs just fine? under xp the second 2 cores don't always max out. If I could create the problem in a different program then there would be some merit to blaming hardware but as it stands at the moment I can't.

edit: have you tried to do a custom run setting the Max FFT size to the max your cache size is? it runs at full load even under xp.

vista pic is just a pic of standard small FFTs.
