I worry for my cpu...

I have an Opteron 144 @ 2808Mhz, Asus A8N32-sli Deluxe mobo, Enermax Liberty 500W PSU. FSB is at 312mhz. In the BIOS I set the CPU Voltage to 1.45V. When the computer goes under heavy load, the voltage is at 1.47V, and when idling, it's all over the place, anywhere from 1.45V to 1.504V. WTF!!!! Will this damage the CPU, and is there anything I can do about it?


EDIT: I'm using a Zalman CNPS9500 and the temps stay around 36-37C idle, and 48-50C load. This comp is rock solid too. RHTDRIBL, Prime 95, CSS, HL2, FEAR, Quake 4, you name it it'll run it forever without crashing.

The fluctuations may be a little troubling, but the actual voltage being delivered to the CPU is not necessarily that high at 1.504v...although, I'm not sure how or if the fluctuations themelves could cause damage. That's odd.

Will the voltage fluctuate if you did something GPU intensive as well? Like, fire up a window of RTHDRIBL and see if it does the same thing?

Using CPU-Z to read voltage, and yes it's all coming from the mobo's sensor. Don't know what to use to check gpu voltage.

Try settting vcore with overvoltage enabled.

Do this at stock settings initially.

I.e., set the normal vcore lower, say 1.25, & then enable overvoltage (it's +200mV).
That will give you a very steady 1.45V.

Did you know that the 8-phase power system that mobo has isn't enabled till you enable overvoltage?

Hence my recommendation to use that method if you're not already.

I found that works better for me.

For example, mine's currently set for 1.285V + overvoltage IIRC, & that results in 1.49V for me which works well.

:( It's still acting up. Even in the bios when I was looking at the voltage it was all over the place.
