On my 3950X, I run it @ 4.125 GHz with a CPU Core Voltage @ 1.188v and SOC Voltage @ 1.075v
My cpu runs way too hot at 4.1 GHz. At core voltage of 1.30 And crashes with a Core voltage of 1.188 and there are several SOC Voltage entrys. Is that a fixed voltage or an offset?
Right now it is running Auto with Cpu Boost, PBO Auto enabled. And hasn't quit (yet). It is running at slightly over 3.9 GHz.

If I'm not mistaken, I don't believe I'm running on Auto, but I'll need to check it tomorrow. My 3950X is due for an update and I always run that in the AM, just in case something goes wrong, I can spend the necessary time to fix it. I do know that I took quite awhile to get it to run consistently at 4.125 GHz, but that was my limit. I couldn't get it to run any faster.
OK, that makes sense. You are running off the default nct6775 driver and the reported Vcpu value is totally bogus.
I guarantee you that if you booted to Windows and checked the value in HwInfo64 that it would be much higher.
What is the value for Vcpu that you set in the BIOS?
The only way to get the correct value in Linux would be to upgrade to the stable 5.17 kernel where the asus-ec-sensors kernel module is provided. That would show the true value because it properly supports your motherboard SIO sensor chip.
Yes, I know that the 5.17 kernel is due to have the asus-wmi-sensors kernel module within it. I'll wait and see when it has officially been released and see what the reactions to it are. If I'm not mistaken, I think that it was said the 5'17 kernel MAY have the asus-wmi-sensors, but if not, the 5.18 WILL have it.
.....[EDIT].....
I can check out Hwinfo64 in Windows tomorrow. The 5950X is on a dual-boot system with Windows 10. I may not have it for long, but I do still have it now.
What water cooler do you recommend for a Ryzen 5950x?
I am confident my noctura 15h ? will never be up to allowing full overclocking.

IMO, custom water cooling is the only proper way. AIO coolers are prone to too many issues for 24/7 crunching.
the Noctua D15 (if that's what you have) is very competent for an air cooler. it's one of the best if not the best air cooler. you should be able to get respectable temps with a conservative overclock. keep in mind, that the 5950X particularly is a very hot running CPU (high thermal density). even with my custom water cooling 4.4GHz @1.27v ran about 80C. and even that wasn't super stable it really needed more volts to be more stable but I was trying to keep temps down.

Unfortunately I don't feel very handy about custom water cooling. Unless there is a complete water cooling DIY kit with a price I don't flinch at I had better go with an AIO.
What has anyone had as their "best" experience (brand/model) for an AIO? Or has a link to a complete custom water cooling kit?
Thank you.

On my 3950X, I run it @ 4.125 GHz with a CPU Core Voltage @ 1.188v and SOC Voltage @ 1.075v
After switching an Asus ROB b450-f MB I tried to apply the above numbers. And the OS died during the boot. I get the parameters for the cpu GHz and CPU Core Voltage. But I need guidance on the SOC voltage.
Do you start with a higher SOC Voltage or a lower SOC Voltage? I can set the CPU Core voltage up to something like 1.25-1.30 and start moving it down. But I am unclear about where to start the SOC voltage and presumable lower it?

Okay Keith, here is my Windows10 version of HWiNFO64 and the Task Manager.
Note: The CPU was running Universe, but the GPUs were not running Einstein.
Plus: CPU Core Voltage (SV12) was toggling between 1.100v and 1.094v in the current position.

Looking over my notes, for SOC Voltage I went from Auto > Manual and started at 1.025v > 1.08125v
I then went into override, going from 1.08125v > 1.08750v, and that's where I stopped taking notes.
So I'm unsure what the reason was for going from 1.08125v to 1.075v, but that's what I have.
Also, my 3950X is on an ASUS Prime x470 Pro motherboard, and it may have slightly different settings in the BIOS/UEFI for setting the SOC Voltage.
Generally it is best to leave the SoC voltage on Auto. That should normally put it around 1.09V.
The only reason to increase the SoC voltage is if you are overclocking memory a bunch. If you run your memory at XMP or DOCP values then just leave it on Auto.
The maximum safe voltage to push through the SoC is 1.2V or you risk burning out the IMC memory controller in the cpu.

You will be using the asus-ec-sensors driver.
