Hi, I was overclocking my athlon x4 840 cpu. And I was very pleased from the results(from 3.7ghz to 4.5ghz).
Maximum reported voltage by hwinfo was 1.43 volts. I added about 0.36 volts to my vcore.
Are these voltages safe and can I go further?
FM2+ socketCan I just check - is that part a Phenom II X4 840 (based on the AM3 socket) or an Athlon X4 840 for the FM2 socket?

It is true that this is a locked cpu. But I increased the bus speed, thus the memory speed is also increased.Hmm - I don't know how you've managed to overclock that then? Officially that is a locked processor and there are no articles I can find of anyone ever overclocking that cpu. Looks like you have achieved a decent overclock on it, I would say that for that generation of cpu, that voltage doesn't sound too high, I probably wouldn't push it much higher though. The key though is to make sure your temps are under control and that the overclock is stable.
