Core Voltage

[Jay Bee]

As title have got a stable clock on a 9550 (2.8 to 3.8) it will go further but gets a bit warm so am settling for 3.8 now comes the question, the clock was a core at 1.187v now I was hoping to back of the volts so as to run cooler, got down to 1.144v (all readings in CPU-Z) but when you push the system to check in prime and watch CPU-Z the voltage goes up to 1.152 and sometimes flicks to 1.160, have tried to see what is doing this in the Bios but nothing has altered.
So the question is will it hurt? and if so what is bringing the voltage up?

Cheers

Low volts

If I put it up to 4.02 and run prime for 1hr the temps are up to nearly 60C which is a bit warm for my liking, the water cooling is not man enough at these settings, if I had a fan cooled water loop it would probley be ok but I can sit alongside the tower(Antec 182 case) and it is all but silent so a bit of the top end of the clock is well worth it for the peace and quite.
Thanks for the opinion though.

Cheers
