Overclock acting weird

[TheTallGuy]

Hello guys. So I recently overclocked my i5 8600k to 5GHz when I noticed something strange while running Cinebench R15. 

When I was running the CPU test I saw that my clock speed was reducing. I tried to give the CPU a little bit more voltage but that does not help at all. Also turning off all the power saving modes for the CPU also don't help.

I attached a video I recorded where I show the problem. If anyone knows the solution to this problem I would like to hear it from you.

that's most likely thermal throttling, check your CPU temps

I will make a video for you where I show you the CPU temps. I forgot to mention them in the post.

These are the temps while running Cinebench R15. My fans on my watercooler are set to 40%.

@Etrecz

your core voltage in CPU-Z and your VID voltage are freakishly stable, there's something wrong, even though VID is irrelevant when overclocking, but still.

 

check HWinfo for all the voltage readings.
