Alright... I've got a P4 3.0GHz and an Asrock P4V88 Motherboard. I've updated the bios to the latest version but it doesn't have any way of changing core voltage. Anyone know of any other way of changing the core voltage? The system is running unusually hot and i think this is the reason for its instability. I would idealy like to change from the 1.4V currently to about 1.2V as i find this reduces CPU temp by 10-15 degrees with little loss in performance. Any help is greatly appreciated.
