To put it mildly yes.
The thermal issues are really bad, far worse than IVY

It is quire ridiculous the chip is running high temps under load, well moderate load things such as P95/IBT are impossible to run.

The heatsink is stone cold, all that heat is trapped in the core, the transfer through the IHS is awful.

I could improve the heat transfer into the IHS by de lidding but the IHS is flush with the CPU and it is impossible to get a blade edge between them.

On my IVY's it was easy to get started on a corner but not so easy with this 4770K.
I will certainly break it if I attempt it.
I don't feel inclined to whack it with a hammer either as that probably wont end well.

The MB is sweet and the IMC in the CPU seems decent.
OK for running the 4Ghz challenge I suppose.

Feel you you dude. What stable clock do you think you'll achieve.
 
We need 8pack to start a delid service, id pay a reasonable fee to have the tim replaced with that liquid metal tim. He could then reseal them with a security seal to stop people buggering them up then blaming him.

Is it better to reseal the lid, or just leave it off?

Either case, I think if there were a pre-de-lidded offer available, I might well pay a £50 premium for it. With the legendary heat issues, I can't see any point in Haswell right now; cheaper to get a water loop and gun for 5.0 on my SB...
 
get out of jail free card? the simple way is to relid it with the liquid metal tim and stick on a hologram security seal at the 2 winged edges; so if anyone reopens it and kills it OC would know.

LoL, If it was that easy why has no one done it and offered the service, l think not.
 
I think its a business idea !!!!
I would say PLENTY op people would pay extra 50f for CPU with liquid metal inside INCLUDING MYSELF !!!!
 
Some chips are just bad clockers regardless of heat so you would also need to speed bin chips as someone who has spent extra on the delid service wont settle for a mediocre clock expecting top 15-20% percentile at minimum and would likely dsr. That can make ppl wary about the standard stock. It requires employees time binning not to forget the the delidding/application/retesting. Plus their the risk of the odd chip delid going wrong and negating the profit from half a dozen or more of delid chip sales. A lot of hassle and extra overhead for low volume and little gain imo.

That is probably about spot on - I can't see any retailer offering this service as it would just be too risky.

There's no such thing. A motherboard with OC presets will give a default voltage for that preset, but the specific CPU you're using might need less or more.

Is there not a default voltage that intel set for the cpu ? I understand specific cpu's may need more or less but there must be spec set for the 4770k .

I'd think that Intel has provided manufacturers with a guideline safe voltage (that information may be freely available, but I haven't looked for it) for some speeds that should allow most CPU's to be stable, but perhaps rather hot. I'll probably be a bit more voltage than the CPU will need. And sure, it can serve as a starting point, but as each CPU and each board is different, when you're overclocking you want the lowest voltage you can get away with for the given speed. It''ll be around 1.3V for the highest clock you can push it anyway (much more than that and temperatures will go through the roof).

I can't remember the voltage when it was still at its default clock, I wasn't interested in those values.
 
Delidding yourself is well worth it and it really doesn't take too long!

My heatsink and heat output of my 3770k was STONE cold before I delidded, only afterwards could I actually feel the heat coming out of my case and my heatsink was warm to the touch.

The 4960x is soldered, which totally knocks the rumour off that the 22nm trigate transistors weren't compatible with soldering.

The voltage at stock speed at load isnt read properly by cpuz . I have everything at default and have only just got the system together ,before i ramp up the clock speed i just wanted to know what the voltage should be under load at the default clock .

Try 1.65 (only just released, I'm guessing). 1.64.0 did indeed not show the voltage correctly, though there are plenty of alternatives.

I think the term you are looking for is VID or the stock voltage. Afaik it's the voltage guaranteed by intel to run the cpu at it's stock speed. However just like the core 2 cpus, you may find that all the 4770K would be running with different VIDs depending on the chip's silicon. So some 4770ks would require less voltage to run stock speeds and some more. It's to do with binning process.
