Too high voltage on i9-10850K?

[WQblitz]

Hi!

I just have bought a new i9 for my new PC with Gigabyte Vision G Z490 mobo. Yesterday I have run Aida64 for a while to check stability of my system. Then I have check voltages on CPU - stable 1.440V on core . CPU was running on 4.8GHz (I didn’t OC, all default settings) with max temp of 80°C (average during stresstest was ~68°C) with my PureLoop 360. Should I reset bios or something? All voltage settings are default/auto there. 
I think that voltage is a bit too high for Intel CPUs and I don’t really know what to do about it. 
(I’ll upload screenshots when I’ll return from work)

Thank you in advance for help

That is way too high of a voltage for 4.8Ghz.  I'm at like 1.38V or so to hit 5.1 rock solid for unlimited amounts of OCCT / P95.

 

It's not a dangerously high voltage just a very pointless high voltage.

It's an i9 on auto, it's normal. Try a negative offset. It can probably still turbo that high.

80°C sounds fine though.

Seem likely with a single core boost clock of 5.2ghz. Guess it wasn't under all core load? Check what voltage it uses in cinebench for example

I don't even know where this 4.8GHz came from. It’s a processor straight from the box, I haven't had time to do anything with it yet

Ok, I’ll try that

The default voltage settings for all Intel CPUs are too high. Intel does this to guarantee long term stability. This was an OK strategy when they were building 4 core CPUs. When building 10 core CPUs on the old 14nm process, this can result in a lot of unnecessary power consumption and heat. 

 

A 10850K is a 10900K reject. The reason the 10850K line exists is because Intel wanted to clear out their excess inventory of cores that needed too much voltage to be a 10900K. I would avoid using default voltage on any Intel CPU but I would especially avoid using default voltage on a 10850K.

 

Here are some examples of the huge difference that can be achieved when you take some time to fine tune the voltage to what the CPU actually needs.

At default settings, the CPU multiplier varies between 52 and 48 depending on how many cores are active.

 

 

Once you get the voltage sorted out, it should be easy to run at 5.0 GHz no matter how many cores are active with far less voltage than the default settings are feeding your CPU now.

 

Edit - I have heard that some Gigabyte boards are extra generous with the CPU voltage that they are using.

After all, I had some free time to work with my CPU.

I tried to set negative vcore offset to -0,105mV and this is the result:

 

 

I hope that voltages are pretty good for 10850K, should I try to change something more?

Thanks for help guys!

@WQblitz Not sure how accurate the CPU-Z voltage reading is on your motherboard. You might be able to use a -150 mV offset and still be stable. What cache ratio are you using? I found that I could reduce the CPU voltage a lot more after I reduced the cache from 47X to 46X. I think the default for the 10850K is 43X.

 

If your CPU is running reliably at 5.0 GHz all core at 74°C, you could just leave it as is. Your CPU is running great without the extra voltage.
