i7 8700k Overclock Voltage Spiking

[pelster900]

I currently manually overclocked my 8700k (4.8 @ 1.2v) and everything is stable, but CPU-Z and other monitoring tools show my voltage constantly spiking to 1.45 when idle, and even 1.49 when I am running intense games with prefer max performance. Not sure what steps I need to take to prevent this. Thank you!

Hi pelster900,

What's your voltage setting? Adaptative?
What's your LLC setting?

I currently have my voltage set to manual: 1.2 V
I had LLC at auto last I checked but can try setting it to 5 in the Asus Bios

I think you can lower the LLC.
The LLC try to compensate the voltage drop during load.

If there is no voltage drop, LLC overcompensate, then overshoot.

The odd thing is that it will hover around .4 - .6 at idle, and then while monitoring it will spike for a second to something like 1.44 or 1.45 even with 0 load. When my fan's all went to 100% and I ran a CPU intensive game at "prefer max performance" the voltage shot to constant 1.49 which scared me so I exited everything and it went back to the .4 with spiking. I was also going to try turning off Turbo in the bios because I thought it may be overvolting even though I have a manual 1.2V set at VCore.
