Safe phenom voltage...CPU-Z or bios?

Hi, i am trying the bump the voltages of my phenom slightly to see if i can raise my 9950 BE above 3.1


In the bios if i set the cpu voltage to 'auto', the Vcore reported by the bios hardware monitor and the Vcore reported by CPU-Z reads 1.36

According to AMD specifications the stock voltages should be between 1.05-1.30...so is this pretty high to begin with?

I've read from others that i should try to keep the cpu voltage beneath 1.4, but should this be the reported Vcore, or the setting that i change 'CPU voltage' to in the bios?

If i change the cpu voltage in the bios from 'auto' to 1.4250, the reported Vcore increases to 1.37 in the bios and 1.39 in CPU-Z.
Is this a safe setting?

the temps at this voltage are below 50...are there any other dangers other than overheating?

Thanks

Is that 50 on idle or under heavy load? I would go with the BIOS figures, since that's a more direct read on your CPU.

its about 45-50 under heavy load (prime95).....when you say go with the bios, you mean the bios hardware monitor yea? Rather than the actual setting i put the cpu voltage as.

if i put the cpu voltage at 1.4250 the bios hardware monitor reads Vcore 1.37....i think thats this Vdroop isn't it?

I understand it will reduce the lifespan of my cpu, but i'd probably upgrade after a year or so anyway. Is that a safe voltage?

thanks
