OVerclocking PentiumD 950

[L33t Masta]

Well, I have 3.93 GHz right now but I don't know what the right settings would be if i switched to manual overclocking to get 4 GHz. My system goes unstable at a 20% OC but thats the next profile up. Right now I'm kicking a 15% OC. What must I do to obtain those magical 7 MHz to get me 4 GHz?

That's not 7Mhz, that's 70Mhz.. Unfortunately I don't know how to OC Intel processors, so I'll leave that to someone else.

Increase cpu voltages, increase ram voltages, lower ram speeds, increase ram latencies, disable anything that interferes with overclocking, better cooling. There is a load of things that can be done. But there are other things that get affected when overclocking the cpu too.

Do some google on research for overclocking your specific processor. I don't know what any safe limits are for it, as I have never used it.
If you go too far you can damage it.

Or maby 3.93 is already its limit.
