I'm not worried, its just I tried for 4.5Ghz, I got to 1.245 volts, and didn't feel like pushing for 1.2500 volts, so I backed off to 1.2000 volts and lowered the overclock till it was stable

My temperatures were completely fine, I was only showing like 54C max on my CPU with my H110, now I'm only hitting like 45-51 when encoding video with mediacoder

Upside is my max power draw for CPU vs my 2600K is 40 watts lower, and mediacoder speed is up .28% for my heavy 1080p encodes

Done with a H110 Cooler

There's something wrong with your overclock or software, my 4770k @4.5ghz pulls over 21fps (average by the end, where yours says 15) in x264 bench.. which is ~1.4x faster.

Okey, so i decided to delid this piece of crap cpu. Cpu died and cracked a few pins on my motherboard, very well it was payday so went and bought exactly the same stuff again..
I thought that maybe i'd get a better chip now since it's been out for while but hell no! This **** won't make it past 4.1 at a 1,275v!
Stayed up for 2 hours reading and writing down stuff from this guide, in the end I turned all voltages up to high levels and turned all crap off to make sure it wouldn't fail..
Now i'm starting to think that it has to be something else! I mean 4.1, come on?

Some tips and tricks?

Same as before: Since you can mess stuff up by throwing too high voltages, try 33x min/max cache ratio, 1.15v cache volts, 1.85vrin, vrin LLC max or 1-2 levels down, 1.23vcore, all volts manual and then raise core clock until unstable in x264 link in OP. Once you have that, you can work up from a solid point. It would be amazing if your chip could only stabilize 40x @1.25 load vcore (these settings)

I guess?

Could be because I got 50 other things running at the time, including a movie and playing Rouge Legacy

How did the CPU die from the delid ?did something wrong accidentally happen ? also, why did the pins break ?

lol for real bro you need to be more gentle and this is coming from someone man handles everything lol:D

if you are bending cpu pins and killing your cpu from delding...you need to take a step back and evaluate the situation lol for real...I have delied approx. 12 or so cpus not a single one has had a issue...

pleae use the vice only method with no hammer or wood block...

also I have messed with 25 or so 4770k's and have never seen one not go past 4.1ghz...so this is an issue on your end with ietehr your board or improper bios settings.

I have no idea dude! I have never broken a pin during my 10 years building computers until now..
When i tried to start up the comp it immediatley shut down, tried the cpu on another board, same thing there!
Then i noticed i bent a few pins on the first board, absoluteley now idea how that happend!
Did all of the above, turned everything up, turned everything with powersaving crap off

Oh and i used the razorblade delid method.. can't say i was careful though..

Well, for best stability testing i always run stuff high prio~ not sure if or how much negatively affected it would be if you're losing out on a good quarter of your encoding speed

Just had a go with my 4770K and i bsod before even loading windows at 1.25v at 4.2Ghz lol. Fun. Cool temps as well. Haven't even benched 4.1 to check if stable.
Its normal right if cpu z shows 1.28v even though i set it to manual at 1.25?
