Overclocking the i5-2500k to 4.5ghz

post #1 of 4
Thread Starter 
is overclocking to 4.5ghz possible by only modifying the CPU multiplier and vcore?

i read all the sticked tutorials, but i can't get my head wrapped around all these terminologies, such as VCC/VCCIO/CPUUIO/PLL/C3

Yes, I'd suggest looking here.

Post any more questions you have

Edit: You stated you may have read this, so just crank the multiplier up to x45 in Bios and find the lowest stable VCore. Start at around 1.38 for 4.5 Ghz. Adjusting those other voltages isn't nessecary at 4.5Ghz

To answer your question succinctly, yes.

If you're lucky, you should be able to get to 4.5GHz just by changing the multiplier. It is more likely that you'll need a small bump in vcore to get there though.

For higher overclocks, you might want to adjust other voltages, or at least take them off auto to have a measure of control.

Those two are really the only things that are changed, besides enabling and disabling some features beforehand (see tutorials). Most people can easily hit 4.5 GHz but from what I've seen there is a wide range of overclocking potential in each individual processor. I think the biggest problem most people run into are the temperatures of an overclocked 2500k, not lack of overclocking ability.

So yeah, as long as you have proper cooling I don't think it should be a problem.
