Wouldn't get past the welcome screen. What should I try next?
bump it to 1.26v.

No if anything it can help an overclock but in some computing your better to have a lower clock and keep hyperthreading on, I don't know which you'll have to experiment but turning it off "should" lower your temps.
Okay success. Worth buying a cooler?
definately

Very nice CPU you have there, what Volts are you using for each 4.7-4.8-4.9-5.0?
And what is the stepping like L413A312?

4.7GHz 1.3V P95 AVX blend stable 6 hrs+, large FFTs stable 12 hrs+
4.8GHz 1.275 to 1.3V IBT AVX, maximum RAM 32GB 2666 MHz, stable 10 passes in ~4 hours
5.0GHz can run benchmarks at 1.35V such as Super Pi but I wouldn't use this for 24/7 use. Can't get stable with IBT or P95 due to 100c temperatures. If I could get temperatures lower my chip would do 5GHz stable for 24/7 use.
Sticking to 4.7 to 4.8GHz for 24/7 use. Had to increase System Agent and Digital & Analogue i/o voltages by +200mV to get all 32GB RAM stable at 2666 MHz. Also CPU cache voltage and CPU VRIN had to be increased to 1.2 V and 1.9V respectively.

EDIT: Currently testing IBT AVX @ 4.9GHz 1.29V.

I'm settling for 4.9 GHz @1.34V as my 24/7 overclock. 5 GHz is simply too difficult to get stable.
Could get bench stable at 4.8 with 1.35v, but bf4 wouldn't have it.
So will likely be sticking to 4.7.
Pity though. 4.8 was a no go even in benches with previous ram.
At least with new ram I no longer get data corruption, etc, when it crashes on unstable oc.

Custom loop at 4.7 with 1.3v gives me high 70s with core 2 spiking at 83c.

Custom D5 watercooling loop with 480mm total rad space and 4x GTs
Just installed this with the Alpenföhn Brocken ECO CPU Cooler - 120 mm and when doing hunts in FFXIV (admittedly pretty flashy) the CPU spikes to 90-100 degrees ... pretty sure that's not how it's supposed to go! Runs idle at around 40 and when not in hunts it is around 80, when FFXIV is in the background while I'm checking CPUID Hardware Monitor it drops from 80 to 60 pretty quick. So... likely air bubbles? I'm not even overclocking at the moment... GPU is fine, 60 or so. Not confident I got that CPU cooler placement done very well, so wouldn't be surprised if it's air bubbles, but yeah.
I have the H80I Mine idles @ 40c as well. I thought It was it was a little hot
H100i. 4790k @ stock (1.184v at 4.4 boost and 1.2 under prime).
29-35 idle.
50-60 in games
70 while priming.
Loving the upgrade from my old i7 950.
Will try overclock it soon, briefly did a quick and dirty 4.6 and it had no issues. Think it's a good'n of a chip but time will tell, truth be told I'm still getting use to all the features and options on my vii hero's bios.

Hi there just a couple of bits, is your last numbers 44? of the stepping as mine is the same, also what motherboard do you have?
