Overclocking 8700k

[Perezz]

I have a delidded i7 8700k that I'm struggling to get 5ghz stable and AVX offset -3

 

Motherboard: ASUS Rog Strix z370 gaming-g matx

Vcore 1.425/1.42v

Temps 38-80°C liquid temp 35°C TWPIN 57°C

Load Line Calibration set to level 6

Power mode maximum performance

Ram set to XMP 3000

SVID disabled

Cache speed 4.3Ghz 

 

Im trying to get a 5GHz clock on all 6 and avx 4.7GHz

I would like 5GHz on avx to but I think I have a bad cpu. 

 

Now I don't do overclocking much I only know a little but before I delidded I used to hit TJMax on 1.32v now I don't even hit TJMax on 1.5v but I don't want to run anyware near 1.5v I only did it for testing and had it for about 10mins as I got coil whine and I dont like using higher then 1.425v

Ideally

 

If any one can help that would be grate. 

 

In Prime95, Asus Realbench, CPUz stress

I have fan Prime95 for 6hrs, Asus Realbench, 30mins and CPUz for about 15mis but I have also run Cinebench R20 a few times and I don't crash even with 1.415v it's only when I use Anthem as a game cpu bench I crash after abou 30mins or so but I dont get GSOD or BSOD or stutter Ingame system just locks up.

i dont even recommend going beyond 1.4v , get that 5ghz out of ur head and just clock the chip on lower mhz, u wont notice that difference most likely of having 200mhz lower or such

Some don't get there. Mine didn't.

 

You basically have to be lucky to get there.

 

As far as I am concerned all i7 8700ks should run like my i7 8086ks. That is 33c at idle even at 5.1mhz without a delide.

 

The real problem is 5ghz is where you get the most gain and the difference can be whether you bottleneck a RTX 2080 ti or not. 

 

Because of my experience with my i7 8700k I will be looking here first before I roll the dice again.

I have seen people get 5ghz with 1.4x volts Hardware Unbox got an 8700k to 5Ghz at 1.415v.

[Mister Woof]

That's a lot of voltage bro

 

Dial it down imo. It doesn't scale linearly, so you probably need way more extra voltage to get from 4.9 to 5.0 than you needed to get from 4.8 to 4.9.

 

My advise is to not go above 1.35v without delidding and LM. I'd go with whatever stable clock you get at 1.35v.

[PopsicleHustler]

I would dial it back to 1.35V and whatever Ghz stable on it. Going above 1.4v is dangerous and will degrade your CPU over time.

 

Also, Frostbite engine uses AVX instructions. Recent games like Anthem and Battlefield 5 will apply your AVX offset. So if you're playing those games frequently, there is no point of having high AF overclock with AVX offset.
