Personally at the moment IMHO I would just run things at stock till you decide what cooler you want to get. As most games even on a stock 8700k you won't have a single problem. Don't get me wrong the 8700k when overclocked is a monster chip and you do get some gains. Thing is when overclocking the goal is to get the most speed with rock solid stability at the lowest voltages possible and it's a VERY fine line and can days if not a few weeks too really tweak.  The problem is with 8700k and it's predecessor the 7700k is they just have TIM which is terrible especially for the price you pay. So your already up against it because the biggest fight straight away are thermals. Hence why alot of people and not even hardcore overclockers delid them and replace the TIM cause they no they can already make there thermals better between 10 and 20 degrees which then means then you tend not to need as much voltage. 

@Jun Wei Goh Asus Boards have LLC (Load-Line Calibration) with 1 as the weakest, 7 strongest. So on your motherboard go for just over half way, if you are getting too much droop then increase the LLC to compensate.
 
@syn2112 Haha indeed, same on mine. Works like a charm. Good thing you posted you had the same issue or I wouldn't have put the answer in this thread. Who knows someone else googling for a solution may come across it now as I know when I searched nobody seemed to have had the same issue.

@syn2112 so after much tweaking and playing around I have sold the issue. Basically put it on adaptive, load into windows and stress test to see how much it vcore it wants to send to the CPU then reboot to get into BIOS and use the offset voltage it to get it to the level you want. You should know via testing in Manual mode to find out the stable OC voltage that works for your CPU. So if it was pushing 1.28v and you want 1.32v then you would want an offset voltageof 0.04.
 
My settings:
AVX Instruction core ratio negative offset: 3
SVID Behaviour - Best Case
CPU Core Ratio - Sync All Cores
Core Ratio Limit - 49
SVID Support - Enabled
BCLK Aware Adaptive Voltage - Disabled
Adaptive voltage - Auto
Offset Voltage - 0.035
.External Digi+ Power Control:
LLC - Level 5
.Internal CPU Power Management:
Long/Short Duration Package Power Limit: 255
IA AC/DC Load Lines - 0.01
.Advanced> CPU Power Management Control
CPU C-States - Enabled
 
If I havent mentioned changing any other ones then chances are its the default setting but do feel free to query away. Obviously I cant state that this will work for you or is the best and most official overclock as I've been tweaking away back and forth for ages... however for me it lets me have a consistent overclock at 4.9GHz without the CPU getting too warm and is stable. Plus when in windows and idle it lowers the speed/voltage like was the end goal.Tested in prime95 for 8 hours and all seems nice and stable with temperatures not exceeding 75C.
 
If you have any issues with stability, disable c-states or up the voltage slightly.

Bullshit.
 
Why would you gimp your Monitor buy just because of the GPU you have?
 
When you upgrade your GPU in 2-3 years, will you upgrade your Monitor too? Probably not.
 
- You will upgrade your GPU 2-3 more times within the Lifespan of a Monitor
- You benefit from a better Monitor (higher resolution) 100% of the time. During Desktop, browsing, videos, and gaming.
- You benefit from your GPU only during gaming. nowhere else.
 
What's the percentage of gaming time? 50% Gaming, 50% Surfing? 25% / 75%?
 
Go more future proof. 1440p is the way to go, if you have the Money for it. And you probably do, if you consider G-Sync.
 
I had a GTX 1060, it works just fine in 1440p. Not worse than in 1080p, you just counter the fps loss with lower settings.
1440p @ High > 1080p @ Ultra.
 
I admit, i switched to a GTX 1080. But i wanted a stronger toy. There was not 1 single Game, that ran not smooth with a GTX 1060 on 1440p. I even got Wildlands (which is a GPU killer) to around 60~ fps with G-Sync, with a Mix of Medium and High.
 
It's just a small compromise in Gaming, for a much larger gain, and a gain that will be present for the next maybe 5 years, 7 years, or 10 years.
 
And why does that work so well? G_Sync. This godsent feature will make the difference between smooth and stuttery. Witcher 4 only 45-50 fps, but still perfectly smooth and playable. Everything on Ultra, except Object Distance and Hairworks. 
 
 
----> Acer XB241YU, or if it's much cheaper: Dell S2417dg.
The Dell is sometimes cheaper than the cheapest 1080p G-Sync monitor.
 
Even without my GTX 1080 purchase, just thinking back at my GTX 1060 + 1440p / 165 Hz / G-Sync.. i did not regret going for 1440p instead 1080p. Not a second. In not one single game.

Just throwing this out there: The unit we use for monitor refresh rates is Hz, not MHz.
