I can think of two things it might be

1. Error with CPU-z
2. Unstable overclock (not too sure if this would cause it or not)

When You OCd did you go straight to 4.0 or did you test in incriments? are you using stock voltage? And like Moto said you should fill out your sigrig. I'd try some lower clocks at first if you haven't.

I'm not familiar with OCing FX chips but it is probably voltage. Ihead to this thread for help

FX club
http://www.overclock.net/t/1139726/amd-fx-bulldozer-owners-club/3800_100

They'll be able to tell you max temps/volts and all that and you'll probably get much mroe help than this thread is getting you so far.

If I'm not wrong, you got that mobo free from microcenter. Right? If so, that motherboard is very weak for overclocks 4.0Ghz and above as it has no VRM Heatsink and I'm sure your voltage is on auto
