Hi everyone 
I've just said hello in the intro forum (over here), so now I thought I'd jump in and start throwing questions at you all
I'm an experienced PC builder, but just a lowly novice overclocker, having only played with it a little in the past. I've just built myself a new i7 4770K based rig designed primarily for music production. When planning it I decided that I wanted to have a go at overclocking this time, so here I am
What I want to do now is check my methodology with you guys to find out if there's anything I could be doing better, anything I'm not doing which I could consider, or any concerns you think I should be aware of. There are also a few questions I'd like to run by you just to clear things up in my mind.
This is the full machine spec - so far I've managed to get it up to a stable 4.2GHz / 4.3GHz turbo (up to 3 of 4 cores in use) which idles at around 30°c and peaks at 81°c at full load on all 4 cores (reached via a 14 hour stress test in AIDA64) on air (ambient temp about 20-25°c). The memory I've got installed is currently runnign at JEDEC defaults, but can go up to 1600MHz via XMP profile which I haven't applied yet. I've gotten this far by reading up and watching videos from people like Asus and Linustechtips.
The settings holding this in place are:
These are the ONLY settings I've changed so far, and it's all been done within Asus UEFI BIOS (updated to v 1502). I've been working to the rule that I don't want the VCore above 1.3v really (I've read that 1.5v would undoubtedly kill it outright on air). I've also attached a Haswell guidance sheet which I found online somewhere. But I've been looking at it with caution since I simply don't know who put it together or how reliable the info is.
The very first thing I did was up the core multiplier, with them synced, to 44 and then up the VCore to 1.200v as a general CPU standard check which was recommended by Asus and LinusTechTips - this wouldn't even boot! So, I've tweaked and changed since then and landed on my current OC. What I'm intending to do next is try to gradually lower the VCore voltage, maybe even put the CPU Input back to 'auto' before hand, and re-run tests to see how low I can get it while keeping stability. Once I know, I'll then switch the VCore to adaptive mode and cap it at that value. I've been led to believe it's best to deal with the CPU first, so I'm not planning to apply the memory's XMP profile until after all of this. Following that... I might go back to where I am right now on the spec above, and try to squeeze more out of it... maybe a fully synced core ratio 4.3GHz.
So.. what do you lot think of that? How do you think I'm doing so far, and does it sound like a reasonable OC for a 4770K on air? Is there anything I'm missing that might help me get more out of my chip, or anything you think I should be concerned about at this stage?
Cheers

The settings holding this in place are:
- Core Multipliers 1 - 3 = 43
- Core Multiplier 4 = 42
- Cache Multipliers = 38 (found guidance on other forums that suggested this is fine and doesn't need to be 1:1 on Haswell)
- VCore = 1.200v
- CPU Input (VRIN?) = 1.950v
- Intel VR Effiency Mode = High Performance
- Intel VR Efficiency Faults = Disabled
