Overclocking 8700k.

Go to solution Solved by Princess Luna,

You're being far too conservative with voltage, try 1.3v to 1.35v it can take it.

Hello!  I am currently trying to overclock my delidded 8700k.  I have it at 4.9ghz at 1.245v currently.  Every time I try to go to 5ghz, windows will crash and give me a different error code each time.  I've tried using 1.275v on 5ghz with the same issue.  I'm fairly new to overclocking so I'm just wondering if I got the worst silicon lottery luck ever or there's something actually going on.  Thank you, Methodic. :)

It can take 1.4V core voltage max, so just keep on ramming it. And yes that's normal, since you're at the point of sacrificing efficiency for more frequency

Aside from also bumping up the core voltage, there a few things more you can do to also increase stability. Under External Digi+ Power Control (or something maybe similar depending on the motherboard) try these things:
- CPU Load-Line Calibration: Level 6
- CPU Current Capability: 140%
- DRAM Current Capability 130%
Also outside of that tab look to set "CPU Core/Cache Current Limit Max" to as high as the BIOS will let you.
Under a tab called Internal CPU power Management you should find "Long Duration Package Power Limit" and "Short Duration Package Power Limit", have both those also set the the highest value the BIOS will allow you. 

The location may be different for those settings depending on your motherboard but this may help you.. You seem to have stated that you already have a stable overclock to all cores at 5.0GHz but I still wanted to throw in my two cents.

Stable in Cinebench R20, 3871 score.  I'm happy with it going to leave it alone now haha :)

 

Cinebench is a decent quick test for immediate failure but I'd try doing a bit longer in another rest such as RealBench.

 

If it can pass an hour of RealBench it's unlikely to be a problem in real life applications.

 

Also I wouldn't go past 1.35-1.375v without delidding.
