It is how I run all my Ryzens. Just pick a fixed multiplier and set a voltage offset sufficient to run whatever clock speed you choose and let it run. Never look at it again.
Stupid question. When the system is not loaded eg. Boinc not running, does the cpu slow down?

with manual fixed multiplier overclocking, no. The CPU stays at full speed the whole time.
What do you overclock your cpu and and what voltage do you use to do it?
This is in the context of BOINC cpu crunching.
Thank you.

ps. Ditto question on 5950. I have one coming in (so far. they have promised).

I'd like to know what voodoo magic you used George to get your 5950X to run at only 1.088V.
How are you measuring your BOINC loaded running Vcpu voltage. What tool(s) show you that voltage?
I run 4425Mhz on my 5950X and my loaded voltage in the Desktop is via the asus-wmi-sensors driver as monitored by GKrellm. That shows my loaded Vcpu as 1.26V. Vsoc is 1.09V
I let my SoC voltage run on Auto in all my BIOS'
If you are in fact able to run at that low a voltage, you definitely have a "golden" sample of silicon.
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.

Tom, as I've tried to explain many times before. All the AMD boosting mechanisms work against running the cpu at full loading. They try and shove way too much voltage to the cpu leading to high temps and low clocks.
Best it to disable things like Performance Enhancer, PBO, CPU Boost and just run a fixed all-core clock multiplier at sufficient fixed voltage to run stably.
I understand your statement. As far as I can tell it is running cooler.

First, a correction: the 5950X is running at 4.425 GHz, NOT 4.475 GHz. The other information is correct, and it is under a full load.....
Here's my picture taken just now:
In case you're wondering, I went off of your guidelines. And I'm using GKrellM and Zenmonitor3.
I cannot use asus-wmi-sensors on this CH8 MB, we tried, remember?
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.

Of course, the CPU speeds for both CPUs are for all cores, consistently.
