Help with ironing out stability on 8350 OC

Lately I've been trying to work on my general system overclock, and the focus right now is the CPU and the NB.  Currently I'm running an [email protected], NB@ 2695, HT@2450.  The ram is just kinda hanging out waiting for some attention after I get the CPU more stable (auto settings on MB).  The voltages are [email protected] [email protected].  I've not been having heat issues under any of my tests (Aida64 for right now) but when I ran a system stress test I got a blue screen.  I re-ran all the parts of the system test seperate and it turned out it was the FPU test that was crashing the whole operation.  Is this just a lack of voltage?  What else might cause this?

Also, since this is the "CPU/MB section" of my system OC, is there any advantage to overclocking the SB?  As far as I can tell there isn't, so I haven't worried about it too much.  Also, from what I've read and been told on AMD it is better to bump the FSB than the multiplier, anyone know how this affects performance in a real world situation (if at all)?  Finally, for testing the CPU/NB I've been using Aida64 as opposed to prime95, because I was reading in a few different threads that prime isn't really a good test, and that it can burn up chips.  I could understand this for some of the newer intel chips since they throttle under a lot of heat, but I just want to triple check before I use it here as a test.  Safe to use prime95, correct?
