Why do you use a positive offset? That goes against the grain.A little higher image resolution please.
1.18 for 4.9Ghz is crazy. Is that a 8700k or a 8600k?
I have stopped at +50mV, level 1, for my 8600k@5Ghz. My gaming benchmarking temps are excellent, so no need for more fine tuning for now.
If you're looking for a reasonably priced and good performing cooler, I've been quite pleased with my Scythe Fuma (Rev. B)
I would definitely be going 280mm or 360mm AIO if it was me.No water cooler?
No water cooler?
I think there is a button there in the middle for 4.5mb sized pic
I used a multimeter this morning. It shows 1.225 volts when running Realbench at 4.9 GHZ so I edited my post. Still not bad.
I may keep it here, I may go to 5.0. I want this thing to last 5+ years.
Moral of the story: If you don't have a multi-meter, you don't have a real reading.
Nice jump from a 2600K running 4.5. That one's going to my nephew for Christmas.

Sounds like overheating. I'd check the heatsink on the gpu first.Im getting a really weird thing happening with my GPU, it will go to 100% fans and then the screen will go black. I have not overclocked it, it's a 1080ti founders edition.
I have been overclocking my 8700k, and stress testing via prime 95/asus real bench - is it possible that caused something to the GPU or power supply? 850w evga supply, so should be sufficient.
Those volts are very good for 5GHz, and you may leave them as is. If you type "goes against the grain" in google, you'll get the meaning.I didn't know the "goes against the grain" expression. I learned something today. Thanks.
So hopefully I will learn something more. So...what do you mean?
Aren't we supposed to use a positive offset in order to increase voltage since we overclock?
I just saw what the built in preset of the BIOS was using, which was +100mV and I have gradually tuned it down to +50mV.
CPUz reads 1.312-1.328V at 5GHz now. From what I read this is an acceptable voltage for 5Ghz on the 8600k, is it not?

I still have to pull the trigger on RAM for my build, I was disappointed by the selection at my local Microcenter.
Is the general consensus that the sweet spot is low latency (CAS 14) PC-3200? I recall seeing that in a review somewhere (can’t recall the site, it’s probably posted several pages back in this very thread!). I’m looking at some G.Skill sticks right now that fit that bill nicely, although they’re not cheap at $279.
Edit: These will be used for overclocking an 8700K on a Maximus X.

Thanks n00ky, already got the 1080 carrying over from my previous build. Can't justify the 1080ti upgrade since I'm only at 1440p.
Personal preference is involved to some extent. I generally prefer to go with air cooling whenever possible, but if I go with water I tend to build full custom loops. The latter would have the best performance, of course.
Since you appear to be building a rig for work, I would think that reliability would be paramount. At stock speeds even the air cooler I linked is more than enough for adequate cooling of an i7-8700K. Even with a mild OC (e.g. MCE enabled to hit 4.7GHz all cores).
If you are overclocking, you may consider better cooling options. A high end air cooler will match or beat most <=240mm AIOs while costing less, so there is also that consideration. The case you have selected doesn't appear to support radiators >240mm so the suggestion of a larger AIO would either require modifications to the case or a different case altogether.
Yes I'm trying to build a rig for work Photoshop, video editing, etc. Never been big into overclocking. Had a Citrix chip way back in the mid 90's that I overclocked. Had a friend that was into gaming and tweaking the clock speed. I liked how well his gaming computer ran so built one with the same motherboard and CPU as his.
Speed is very important to me but I do not want to risk reliability. If the computer gets unstable and crashes during the long render, or a complex Photoshop operation, then all the speed is worthless. And I really don't feel like doing a bunch of custom water cooling to get overclocking. I have a water CPU cooler in my rig that I am running right now. (I7-3930K) At the time I bought that CPU that cooler was the only option. Intel liquid cooled thermal protection for LGA 2011.
I can happily run an air cooler if that is adequate for this system.
Any opinion which of those motherboards would be better?
Does anybody on this thread have the 8700K with the Optane SSD 900P? Curious if that is as fast at it seems it would be?
Mid to high end air is fine with stock 8700k settings and even MCE. I'm running all core turbo at 4.7ghz with a U14S and it's working great. Really, unless you're pushing 4.9ghz+ air is great and if you want to go faster it's time for a delid and possibly even custom water.
Not planning on deliding. I still like the AIO coolers though. I may still do that.
What does "MCE" stand for in this context?
You are. The normal routine is to set say 1.330v for your 5GHz overclock and then use the (negative) offset to cut down on the volts until you start experiencing instability, then you up it a notch to stay stable. But you set a lower vcore and increased it with a positive offset. Both work to get you to your desired goal which is why I said you could leave it as is, especially since your overclock is really good for that voltage.For now I'll leave them as they are, since they are OK.
By your expression, I figured that me using a positive offset, was doing the opposite from what others were doing. At least that's what google found out. Against the grain means doing the opposite.
So aren't others using a positive offset? That's what got me confused.
What I got for that purpose is this (usb 3.1 gen 2):Worked on a wishlist on Newegg today and when I started the 8700K was available. By the time I finished my list it was sold out. Oh well, I wasn't going to order today anyways.
I have decided on a CPU and want to use Optane SSD 900P, but keep going back and forth on motherboards. I have used Asus many times, but Gigabyte are good too. Here is my list. You will notice there are two motherboards there an no CPU cooler. List isn't final yet. Looking at about $2700 total build with today's prices.
I have several 4TB harddrives that will be swapped in and out of the hot swap as I need them. (video editing etc...)
