i5-2500k Going to 5GHz

[Epideme]

Hey, I have a few questions regarding overclocking my i5-2500K to 5GHz,

Is a coolermaster hyper 212+ sufficient for 5GHz everyday use? i have 6 case fans (3x120mm, 1x140mm, 2x200mm), and an NZXT Phantom case if that makes any difference

And what settings would you suggest for going to 5GHz? Currently it is running stable at 4.8GHz, (26 Hours test on Prime95 blend), with multiplier on 48x, and CPU Voltage 1.375v, it definitely can be stable at 5GHz, as my friend tried it in his computer and managed it for 24hours on Prime95 blend,

Also, i cannot find anywhere in the ASUS Bios for my mobo (ASUS P8P67 Pro Revision 3.0) an option to enable 'Internal PLL overvolt'

I am very new to overclocking, so layman's terms if possible, any help is much appreciated

Depends on what temperatures you're getting under load, anything under 80 degrees at that clock speed tbh.

As for settings it's specific to the CPU so you'll have to determine this yourself.

Try running IBT 20 times on Max ram and 4 threads to see what your max temps get too, if they're over 75C I'd say you may struggle to get to 5GHz with that cooler without them going over 80C.

I don't really see the point, as it would make no difference to frame rate with a single GTX580 as for all games bar game that runs on single core (i.e. WOW) or two. So why would you want to push the voltage further up for the sake of extra 200MHz that's not gonna provide real-world performance increase and risk shortening the lifespan of the CPU?

Off topic, but might as well say, your sig is too many lines

That sig is almost as fat as my mother.

I agree with you. However, it's the nature of the users of this forum to want to get as much juice as possible out of a CPU. 5Ghz also seems to be a magical number that people aspire to as well.

I think you will struggle to hit 5ghz on that though. Something between the £70-£100 mark like the Noctua or H100 would be a good bet.

I have the hyper 212 plus and Im happily running my i5 at 4.5ghz with vcore of 1.295 on load using IBT. Top temp is 74 deg celsius with a room temp of 24. Im waiting for a silver arrow now, lets see how it performs.

Forgot so say, I think the hyper 212+ is not capable of 5ghz OC if you want to maintan below 72deg C.

ah, thanks.

Okay, i'll give that a go and post the results, cheers.

As for why? I don't know in all honesty, it's a challenge, i know the chip is capable of it, so why not? also, 5GHz is a nice number and also, i got to 4.8 without really trying, i'd like to practice getting it as far as possible for future chips.

You can check how far you can push the chip on what you have, these SB chips idle very cool. The moment you see your clock hit 80C with intel burn running, it's time to stop heaily benchmarking. But that doesn't mean you have to stop pushing the chip and seeing how high it will go, within reason.


My cooler is only good for a 24/7 @ 4.6ghz, but I know my chip goes all the way to 5.4 and is stable enough to run a very fast [time wise, at load] 1M Pi run. During all this the cpu runs at under 80c... but if I ran intel burn, yeah, it would probably blow up.

I say within reason, because I'm pretty sure it would blow up if I tried for 5.5.
