Help me reach 5GHz+ on my de-lided 8700k

I followed Nate152's instructions for someone else(https://rog.asus.com/forum/showthread.php?100733-My-first-overlcock-i7-8700k) and was able to get to 4.9 stable but occasionally BSOD's at 5GHz. I just de-lided my proc with RockitCool's kit and their copper IHS. I have not tried overclocking since I did the de-lid 2 days ago.

Here are my specs

Phanteks Enthoo EVOLV MATX TG
Asus ROG Strix Z370-G Gaming AC
i7 8700k @ 4.9GHz (de-lided with RockitCool' copper IHS and Coollaboratory Liquid Pro) idles under 100F
Corsair H115i (pump on extreme and fans on quiet)
32GB G.Skill Trident Z 3200 14-14-14-34 (samsung modules)
Asus ROG Strix GTX 1070 8GB
Samsung 960 EVO NVMe M.2 500GB
Corsair RM750X Gold
Windows 10 Pro x64

I have HWInfo64 and RealBench installed.

Here is a screenshot of HWI after running RealBench de-lided @ 4.9GHz

Here are pics of my BIOS changes to get to 4.9

I hope I have provided all of the information to get me rolling. Looking forward to hearing from Nate152 😃

Hi matt

Looks good !

Set SVID Behavior to Best Case Scenario.
Set the cpu core ratio limit to 50.
Enter in 1.350v in the "additional turbo mode cpu core voltage override."
F10 and Enter to save and exit, run Realbench to see if you pass the test. Post a screenshot when the test has finished.

Hwinfo is showing a bunch of settings not being monitored, have you changed anything? Here is how it should look, what I have circled is the cpu speed, cpu voltage and and cpu temps.

RB ran without a crash and I ran Prime95 for 10 min with no errors (P95 was erroring out @ 5GHz before the de-lid). Temps are awesome too!

The image editing score is a bit low, the time should be down closer to 20 seconds.

Try rebooting and run the test again and see if the image editing score is any better. If it's not any better, you may need a little more Vcore for a proper score.

How much more Vcore?

All right, I think the image editing score could be alot better, try raising the Vcore .01v to 1.360v and try the test, if it's the same try 1.370v and up to 1.40v if needed.

Here is my realbench score, see the image editing score at close to 20 seconds.

Ok, I think I have settled on 5GHz @ 1.390. 1.400 was a tab hotter and only a couple of points higher compared to 1.390. I tired 5.2GHz @ 1.400 and it BSOD'd halfway through a RB benchmark. I am chalking up your better scores to being oc'd to 5.2 and having a Titan XP video card 😃 DO you think oc'ing my 1070 would make much of a difference?
