I7 8086k overclocking issues

Hello, my name is Aleksanander Stojnsek, and i'm from Slovenia (that’s why my english is not perfect). In december 2018 i bought my new cpu i7 8086K, i pick this cpu instead of cheaper i7 8700K, because i want to avoid silicon lottery, and get the cpu that can hit 5ghz on al cores, with lower voltage. Few days ago, i finally decide to overclock my new cpu, and see what is capable, the final result was huge disapontmant. I saw some i7 8086K hitting 5.1 Ghz with 1.3 voltage, and even the vorst samples can hit 5 Ghz with 1.3 voltage, but my sample its not stable at this voltage, i try 1.33 voltage (because of high temperatures, i didn’t go higher) for 5 Ghz and  it’s still not stable. I pay 500 € for cpu that can’t hit 5 Ghz with resonable voltage, i could get i7 8700K for 100 € less and I would probaly see better results. Some i7 8086K can hit 5 Ghz with 1.2 Volts but mine can’t even hit 5Ghz with 1.33 Volts (I need 1.3 Volts to get 4.9 Ghz stable, so I will probaly need at least 1.35 Volts to get 5 Ghz stable, that’s just to much for a i7 8086K), i think I get defective sample (average 8700K that was not even binned properly). I realy don’t know what should I do.

 

Edit: Im using ROG STRIX Z370-G GAMING (WI-FI AC) with updated bios.

Gonna be completely honest, it's a bit of a gimmick. Overclocking is never guaranteed, there's always silicon lottery. However, have you tried load line calibration yet?

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - dark mode Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad

I follow this guide, so i set load line calibration to 6

Yeah getting an 8086k doesn't mean you will get a great overclocking chip but rather one that can reach the required base and boost clocks if the 8086k. I always thought it was weird that people would assume this. Anyways you could have just turned MCE if you wanted 5ghz on all cores. The temps issues seems like you just don't have enough cooling to overclock properly.

Yeah that 5GHz advertised by Intel is just the single core turbo, other parameters are the same as 8700k. You really should have asked here before buying the 8086k.

8086 should hit 5ghz with 1.3 volts (some samples hit 5.1 with that voltage).

For colling im using Intel Thermal Solution TS13X (BXTS13X), im waiting for evga clc 280

*should* being the key word.

 

I cant overclock my FX 8350 for ****.  Most people can get it to 4.6 - 4.8 OC, with some getting 5.0ghz.  Me?  4.4ghz and it cant even stress test without locking up PC.  I gave up because it just...wouldn't...take an overclock well.

How can be my sample so much worse?

Worse?  Does it run at the advertised speeds it was sold to you as?  Than its working as intended.  You cant guarantee an overclock, like everyone else said.

I read all rewiews (amazon, newegg, geizhals...) and i couldn't found a sample that overclock so bad like mine, looks like i get the worse i7 the worst sample.

I am going to be completely honest as a fellow owner of the 8086K and an 8700K they overclock about the same.  My 8086K can boot and run games at 5.2 @ 1.36 vcore with no offset and my 8700K can boot and run games at 5.1 with about that vcore too.  They are the same processor essentially also, double check that you have turned off Multi Core Enhancement.

 

Silicon Lottery actually told me after delidding my CPU that I would require 1.412 vcore to get 5.1 on the 8700K and 1.410 vcore to get 5.1 on the 8086K both stress test stable.  So essentially the same thing.

I can also boot and run games with 1.28 voltage on 5 Ghz, but i cant past OCCT test even with 1.33 volts.

@svenhassel Since not all processors are the same, that guide you used may need to be tweaked a bit in order to make it work for you.  Intel datasheet says that 1.52 vCore is the maximum that the CPU can handle.

 

https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/8th-gen-core-family-datasheet-vol-1.pdf

 

Page 123 if you are looking for it.

 

I am wondering why you are so concerned with going above the 1.30 vCore.  If your cooling solution keeps the CPU below Tj Max by a decent amount then why are you specifically worried about it.  When I benchmark using my PC I push my overclock up to 5.35 Ghz @ 1.49 vCore and the temps never go above 89° C.  Yes I know that the higher voltage COULD potentially decrease the lifespan of my processor, however I am not using that for a 24/7 overclock.  Silicon Lottery even shows that on their Delidded CPUs you needed to use between 1.4-1.425 vCore.  I got a bad chip too, but I was getting 5.1 Ghz non-delidded @ 1.36 vCore and it was getting to that same 89° C.

 

I have not watched the guide you used, however things to make sure, Multi-Core Enhancement is off, Short and Long Duration Power Settings are at 4095.

Higer voltage higher temps, difrence between 1.3 and 1.4 volts is 15-20 °C.

I gues i will just use 4.9 Ghz with 1.3 volts, thanks for your help.

Hello I finally managed to pass an OCCT without error

1 hour test, large files, avx 2

8086k processor

Aorus Master Z390

vcore 1.33

Are these results ok? For some people it seems they are average and for other I spoke about it they are very bad for this chip

I would like to set up an adaptive profile but not so sure how to do..

Also should I leave c state and speed shift enabled? 

Thanks

so speaking from experience

 

while it sucks you can't get 5ghz

 

4.9ghz is imperceptible from 5ghz in actual use

Before you reply to my post, REFRESH. 99.99% chance I edited my post.
