External Clock ???



Sys Config details shows a list of all the clock speeds for the devices I am running.

What exactly is the External Clock?, and is there any way to OC this particular clock. Preferably by software, as the MOBO in question is a laptop one that is not very accessible.

I have increased the FSB, PCI-E, and GPU clocks already, but they show NO CHANGE to the "external Clock".

Surely somebody knows what this is and how to change it.

Thanks in advance.
