my i7 4790k haswell is burning while working

[OneMoar]

It is most definitely 0.1V. Look at Haswell overclocking reviews if you don't believe me.

Its 0.1V if you are using AVX or applying heavy FPU LOAD else its 0.01 or whatever you have defined via your combination of LCC/adaptive voltage
again its not randomly adding voltage unless the chip calls for more on haswell if you apply FPU load it will start asking for a bunch of voltage to handle the increased workload
I can run linpack all day and the voltage will never go above 1.168 @ 4.3Ghz
if i run a SMALLFFT or any small data-set test it will go up to 1.264 even if i drop the voltage to and lcc down a notch it still hovers around 1.250 even at stock if you run a small-dataset test such as prime95/occt it will still add 0.1v BUT ONLY IF YOU ARE RUNNING SMALL DATASET not under nominal load such as gaming or encoding ...

its perfectly normal and perfectly safe so long as you are paying attention ...
has nothing todo with overclocking in of its self its just how haswell operates

This is the argument I am trying to get across. Running a AVX test like prime95 small FFT is unrealistic for everyday computing, and while the processor won't die, overheating is normal. Intel has already moved in the direction of reducing clock speed when running AVX loads on their latest processors in order to prevent this exact scenario. The Haswell-E Xeons have different clock profiles for AVX loads versus everything else, with the AVX clock speed being about 400MHz slower. This is similar to how GPU manufacturers implemented power limits to prevent GPUs from dying under Furmark.

either way 1.2 to 1.248V isn't gonna cause any damage for short bursts
my chip is pretty crappy tho it won't do more then 4.3 without >1.264V @ avx load

Why use LLC and adapatve voltage?

I leave LLC on auto and use manual or offset depending on what power play I want to be in at that moment.

Im afraid to say this but as much as yall say its the same as a 4770K your right and wrong all at the same time.

Whats the dio/aio voltages on the 4770K's vs the same on the 4790K do you know?

The DC chips use voltage differently then a regular 4770K does. Ive been playing around with this chip long enough to know there is really a difference between the 2 chips.

But whatever this could be an endless debate but to the OP good luck and hope you get this issue figured out.

because some of use care about power consumption and noise
no adaptive voltage means the proc won't throttle down at idle

@OneMoar

I think you need to re- read my post because your comments about some of us care about power consumption and noise isn't making sense. I just explained on how to save power and lower noise lol

I don't use adaptive voltage, I use auto for LLC, and I use offset. My rig powers down to 800mhz and goes from there to anywhere up to 4600mhz.. You don't need adaptive to achieve this. Under CPU in the bios there are your power states and by default its set to auto. If I use enable ,it opens up a shit pile of options to set but I just leave those settings alone.

I use offset of + 04 and enable in the control center under power options BALANCE plan and within a couple of seconds the core speed drops to 800mhz and voltage is real low plus my watt meter shows about 33watts when the rigs been sitting for a few minute's ... So there is how I run a well tuned machine with using as little power as possible

my board won't drop the multi using offset ... witch is odd ///

 

[Kursah]

My issue with only using offset voltage is that the offset is applied to all ranges of CPU core voltage, what I mean by that is idle-load-turbo. That's why I prefer to use Adaptive voltage where the extra voltage is applied only during the Turbo clocks, leaving the stock and max stock clocks at stock voltages. At least that's how it works on my board.

@OneMoar that is odd... my Asus Z87 Pro drops multi to idle just fine when using Offset voltage. Right now I'm running my 4770k at stock clocks with a -0.130 undervolt applied to offset. But no issues aside from that.

Maybe BIOS upgrade/downgrade necessary? That should be one of THE Asus boards to own for Z87 I would imagine it shouldn't have that issue or bug, but I'm curious in finding a solution for it.

I don't use LLC I just use offset, less risk of continuously overvolting it for short intervals.
