Having difficulties overclocking up to 5Ghz, any tips?
Tried pretty much everything that was in the OP but no luck.

It might just be that your chip might not be able to get to 5ghz? Keep increasing vcore until you can run p95. There isn't really any magic setting, either you will be able to boot and fail during stress testing, in which case tweaking with voltages will help.

I've had the chip at 5Ghz, although only during bench runs.
It requires too much voltage, so I was thinking about if there were any other options that I hadn't tried that could bring the voltage down to bearable levels.

this is what happens when I try and take my 2500k to 4.2. there must be some setting in the bios i goofed up. I followed these steps exactly from a bone stock setting. the only thing I changed is the multi from 4.8 to 4.2 because of my shoddy cooling situation for the time being. i used "two cables" template, followed those steps exactly from a stock setting. Idk anything about intel, this is my first intel chip since high school. is there something I missed ? Does the i5 cut down on the overclocking when it's in a near idle state ? thanks for your help guys.

the steps I followed are here, about half way down the page.

Awesome guide for us beginners, perhaps if I get a 2600k ill look back, but im more inclined to wait it out, hopefully you make another guide for Ivy bridge CPU!!

Those temps are fine. Pretty respectable in fact. Very few programs heat a CPU like prime95.

Thats your cpu downclocking at idle, try turning off speedstep and c1e. It should stay at your overclock speed now.

There not bad, could be better for sure. I think your hot ambient probably isnt helping. For reference I get just a couple C more during my p95 and thats at 1.4v.

If you set your vcore to 1.70, in windows it might drop to 1.684/1.690 for instance with a good LLC setting, but it wouldnt stray too far from your setting in bios. However, you go by what cpu-z says in windows, the actual volt is what you see in windows, not what you set in bios due to vdroop and the loss of voltages to prevent the cpu from being overvolted when under load.

On a side note you say you set your vcore to 1.40 and you get 1.404 in windows with LLC, but without LLC you set your vcore to 1.45 and it drops to 1.404?

Surely you have misread that? Ive not heard of such a big vdroop, a couple of incremements is expected (like 1.410 to 1.405/1.400, but not 1.450 to 1.400)

If I only want to overclock to 4.0Ghz, is it really necessary to change all those settings? I have never overclocked my CPU before, only have experience overclocking my graphics card, so changing settings around in the BIOS and all that has me nervous.

I have a i5 2500K, what does [email protected] mean?

My motherboard is the Gigabyte Z68X-UD3H-B3, and I have liquid cooling for my CPU so i'm not too worried about temps getting too high. I might actually go for 4.5Ghz but even then, do you still recommend changing all those settings or is that best for the people who want 5.0Ghz? Quite a few guides I have read suggest all you need to do is change the multiplier to 45x and then the vcore to 1.35v and then keeping dropping your vcore until it becomes unstable, any thoughts on that?

Thank you for your time, just trying to absorb as much knowledge as I can before my computer arrives hehe.

I get the feeling it's going to be extremely tedious to go past 4.5 with 100% stability.
This is why you get a higher-quality board with better VRM's.
I'm at 4.5GHz w/1.32v and I pretty much just guessed everything. Its 100% stable too - I'm sure I could go higher without much trouble
