CPU Voltage problem

[MarcoAzarmaneche]

Hey guys ! I recently build a PC with the following specs: Rampage V Extreme, i7 5960x, SLI 980ti's etc.

 

I did no overclocking, I just loaded ASUS's optimized profile for the cpu. Now, at no stress (fully idle - 2%) it has like 40degrees Celsius. Ok... so i went to investigate. In CPU-Z it shows that the voltage keeps going up and down from 0.720 to 1.100, without any stress, therefore the core speed going from 1200 to 3000-ish.

 

Can you please help me? Thank you !

When the CPU isn't being used, it'll downvolt and downclock to save power and cooler operation

I know it does that. But it does it like 2 times a second. One second is at 1000Mhz, the other second is at 3000Mhz

Yeah, that can happen if there are background processes

No background procceses. In task manager for example it shows cpu is used at 1%

Don't worry when the CPU is idle it will lower voltages and speeds

That's fine, no need to worry about it. It's how Intel's EIST and C1E work, continuously alters the speed as an "on-demand" basis, basically background tasks will be causing it but it's normal.

That's it... that 1% can be caused by system processes like networking, drivers, antivirus, etc...

Okay, if you say so... But I still think it happens too fast... As I said, in 10 seconds it happens like 4-5 times..

It's actually happening much faster than that, just the monitoring program can't update fast enough. Mine does it from 1.6GHz to 4.2GHz constantly swapping on all cores, unless I launch a game then it just pegs at 4.2GHz and stays there.

Thank you all for your help

Truthfully it is probably happening many many more times than that. but the task manager only takes a sample once every few tenths of a second. It is absolutely fine.
