Advice on, low risk, low hassle i5 2500K overclock

post #1 of 10
Thread Starter 
I've never overclocked anything before, my this shiny new i5 2500K has me wanting to give it a go. I only want to bring the clock speed up to
3.8 - to 4.0 range.

I have a an Asus P8Z68 Deluxe mobo.
My understanding so from all my searching is as follows -

For such a mild overclock simply raising the multiplier to 40 (Turbo Ratio "By all Cores")??

And that's it, stock voltage settings, everything else left alone.
I already messed up my Bios once by flipping a switch I shouldn't have and the box went back to the shop. Now all is well back at stock clock speed, but I'm VERY reluctant to tinker again.

I've skimmed over the long, involved guides, but frankly I don't have the time or patience to learn it all from ground zero right now. If I can do it easily, great. If not I'll live with my stock clock speed. (which would be a shame, given the potential)

PS. I am continuing to read this board and find someone else who posted a similar query. Any help EXTREMELY appreciated.

Cheers

Not all the cpu's are the same, you could try that if you want, but the best way is to slowly bring up the FSB or multiplier in your case, testing with each step, it's a very time consuming process, it took me a week of tinkering to get my old rig stable. Now im no i7 expert (i've never had an i series processor yet), but from my little bit of experience and being given advice taking small steps while raising the voltage if needed should help. Im not sure how the multiplier works with the voltage, but im assuming the higher multiplier needs more voltage so take small steps.

Simple. Change the multiplier to 40 and go. Should be all there is to it. 99% of i5 chips can do that without changing any other settings. In fact, I could take mine to 42 without changing anything and it was stable. Ignore what aulex said about changing the fsb tho, dont mess with it for i series chips.

Keep in mind that what you are changing is the turbo multiplier, so when you pc is under load it will go to 4.0 ghz, when not under load it will clock down to 1.6 or so, this is normal.

Up the mutiplier to 44 and VRM Frequency to 350 and you should be solid as a rock mate!

With a modest overclock like that, you should be able to set the multiplier to 38-40 in one go on stock voltages. If you boot up and hang or get a BSOD, no problem, just go back into bios and up the voltage (vCore, etc depending on your mobo) by one notch and try again until you can boot up and run stable under load (using Prime95, Intel Burn Test, or LinX for a few hours). Even with stock cooling, you might be able to hit 4.5 with modest voltage and temperatures.

A lot of people can get their 2500k up to 4.0 with only changing the multiplier. However, raising the multiplier too high w/o adjusting the voltages can make the chip unstable. I would suggest first off to get a good heatsink for your 2500k. The Cooler Master Hyper 212+ is a great cpu cooler and will only set you back ~$35.

However, with your i5 + mobo setup, it looks like you dropped about $450. I would suggest looking at some of the beginners guides to overclocking. http://www.overclock.net/intel-cpus/...ing-guide.html is comprehensive and an easy 15 minute read. Nobody will feel sorry for you if you fry your chip and you don't know what prime testing is or what offset means (well, most).

OK, I'll give it a read.
Thanks

First, you aren't going to fry anything since you arent changing voltages. Just change the multi and you will be fine. I would start by changing it to 42, IOC bet that would be stable. Also, you will be fine with stock cooling with a mild OC like that, though I will say that a good cooler is a very good investment. The hyper 212 is cheap and works very well.
