I bought a new gaming rig recently. The cpu is a i5 2500k and the mobo is gigabyte so I can use their utility to oc.
In some forums I read something called active cores, when you increase cpu Ghz ( oc it ) the number of active cores is decreased.
What does that mean ? If I overclock my cpu, does that mean the number of cores that can be used by system is reduced ?
BTW, Is it safe to overclock the cpu with the stock cooler ? I didn't buy any extra cooler.
