[iCUE is causing voltage problems on Zen 2]

See this:

 

That's from AMD. Hard to say what Corsair could do but I guess we'll see.

 

I have to turn off iCUE to get the vcore back to around 0,9v.

Even with HWinfo on, and iCUE off, the vcore still drops to 0,9v. Just not as often when i close HWinfo.

 

So atleast for my system, not using iCUE fixes it for me.

When you completely close iCUE the voltage come down from around 1,4v to 0,9v.
