Unfortunately I never found a solution and got a refund
You can try without Armoury Crate but I doubt it was a software issue (BSOD or other errors expected in this case, not sudden reboots IMHO). On the Net I've seen in the past other AMD CPUs had this issue, so it's probably a batch of faulty CPUs (or their internal faulty APU).
