So I like the idea of SiliconLottery to buy a binned chip. However they use quite high voltages for the i7-6700k (Vcore):

4.9 GHz: 1.44V

4.8 GHz: 1.424V

4.7 GHz: 1.408V

 

Sure, the voltage is "up to" but you can end up with such a chip. But this voltags are not considered save for 24/7, are they?

High voltages on Skylake are perfectly safe, that whole 1.35v shit is BS on Skylake, want to know why?

 

Skylake doesn't have cache voltage or FIVR like Haswell did, the chips run a lot colder by default, and temperatures DO play a part in degradation.  Skylake now gets it's cache voltage from VCORE voltage, unlike Haswell that got it from it's own voltage.  Haswell had Vcore, Cache voltage, VCCIN, etc, Skylake just has VCORE for cache & core voltage now, which logically would make the default & "safe" voltages higher, since that voltage goes to separate things now.

even buildzoid says that 1.35 is the highest you shud go for 24/7 when you want the thing to last

So, the frequencies are BS as you can't run them for long without killing the CPU?

I bought my "4.8 at 1.424v" 6700k from SiliconLottery last year on May 3rd, I received it a few days later.  I ran a daily 4.8 at 1.39v with my PC on nearly 24/7 up until about February of this year if I remember right, in which I met with a fellow HWBOT member IRL and got a delid tool from him.  I delidded my CPU and put CLU on it, which allowed me to run 4.8 at 1.375v 24/7 and even tested it in prime95 with the settings outlined in the Skylake OC thread over on OCN a few months ago.

 

In late february and march, I dove into HEAVY dry ice overclocking with the SAME CPU, and set many records on HWBOT for the fastest 6700k on dry ice. I proceeded to do 2-3 dry ice sessions at 1.6-1.7 volts at -70c on the CPU pot, each session lasted a few hours each. I ran HWBOT Prime, Cinebench, and all kinds of other tests at ~5.5-5.8 Ghz. Most recently I did some firestrike in April of 2016, with the CPU at 5.7 Ghz 1.696v for about 2 hours at that same ~ -70C CPU pot temperature with dry ice.

 

After all that, I've been running 5 Ghz at 1.43v in BIOS for nearly all day every day ever since, with load temps in the ~45-60c range depending on what game I play or what benchmark I run. In prime95 small FFT I see load temps about ~72c at these settings.  I've yet to see any sort of degradation, or BSOD.  I've seen a few random NVIDIA driver issues that caused the PC to lock up, but no CPU related issues from what I can tell.

 

All the dry ice sessions can be found in my post history, as well as my HWBOT profile btw.

pretty much , you can run the thing but it wont last you , it will degrade rather quickly 

id give them a month up to 3 holding the frequency at that voltage before they become instable

No, it's more if you go above 1.35 volts on Skylake for long periods of time it'll hurt the chip's lifespan. 

Where are you getting this? Read my above post, go read on OCN in the dedicated Skylake OC thread, TONS of people are running 1.375-1.425v and I don't think I've seen anyone complaining about degradation.

Ok thank you. My plan to buy from them just died. Is there an other platfrm selling binned chips at reasonable voltages?

I think they're full of shit making big claims to get your monies. The wording of their return policy and warranty is ok by me. I find they do not have confidence in their product because they only give a 30 day warranty.

Ok, 4790K do better overall, look at what the VCORE max is for them at 4.9GHz: https://siliconlottery.com/collections/1150/products/4790k49g

 

And doesn't Skylake handle higher voltages a lot better anyway?

Pretty sure skylake likes more voltage anyway. 

Yes indeed, due to having it's cache voltage come from VCORE, unlike Haswell that had it's own voltage for cache & v core.  Skylake combined both those voltages into VCORE.

I find it beyond impressive that you estimated the life span of a chip at a certain voltage.  Skylake can handle higher voltages just fine.  It'll be fine much much longer than your 1 to 3 month estimate.

I'll be giving that a shot then-the fan Cooler Master use on their coolers is annoying with my 4790K above stock.

yeah well, you got the Seidon which has the shitty fan. Shoulda gotten Nepton ones, that has the good silencio stuff.

Is there any site doing this that is located in europe? Because import duties in my country are extreme if it's from outside europe.

It's very informative and helpful, thank you.

It is also marked as "best answer". :)

So what is the safe voltage on an i7-6700K then? I don't think I understood you fully. I just got an i7-6700K and I'm in the process of overclocking it. Is running the CPU over 1,35V safe for 24/7 use considering my board is an ASRock Z170 Extreme4 (should be fine for this kind of overclocking) and my cooler looks like this? (should be sufficient as well, though I removed the third fan yesterday so it's got two 120mm ones now only):

Intel spreadsheet on it says max voltage should be 1.52v, but temps would be way to high to be safe for 24/7, asus has said 1.4v on air and 1.42 on water if I remember right.  

 

If you can keep temps nice and low, I don't see why 1.4v-1.45v isn't safe.  But if you're like 85-95c with those voltages then it certainly isn't safe. 

Heat is the enemy with high voltages, it will cause degradation faster.

That's why I'm only running my 4790K at 4.7GHz 1.34V, it gets too hot at 4.8GHz 1.35V with the current fan on the AIO (there is a 10oC difference, under a full non Prime 95 load).
