OCing a non-K Intel CPU

[Mo5]

Why are people saying that you can't OC a non-K CPU. The i5 3570 and 3570K are the same CPU, running off the same chipset - I can't see the reason why it shouldn't. Can't you OC 'old' school - by increasing the base clock... I still call it FSB :D

Dont intel lock the FSB?

I don't know. I still live in the LGA775 era xD That's why I asked :P

id have to look into it but its a hell of a lot easier just changing the multiplier anyway the K is generally more or less the same as the non K anyway also Intel offer an overclocking friendly warranty on the K series i.e. if you fry it they will replace it no questions asked for like $20

that and its generally not a good ideal to go messing with the FSB

But I used to increase the FSB all the time. And you could just run a divider for the RAM. I don't see any problems, unless they lock it, which would be strange o.o

I believe it has something to do with the memory controller and other things now being on the CPU die and change the FSB too much mean something just will not work (don't quote me on it tho) and non k chips do overclock a little just not as much as a K chip

As others have said, overclocking using just the unlocked multiplier ( on -K versions) is a lot easier and provides much greater and more stable overclocks. The FSB on more recent chips ( sandy and Ivy) is used to control many other things, so tampering with it can easily cause instability among other problems; hence why it's not generally recommended. Having said that, Intel's Turbo Boost feature will still allow you to overclock slightly, but just not as much as a -K version of your chip.
