PC Processors

[K911]

Hello.

Right now, I have the PC with Ryzen 7 5800X since autumn of 2020 and I'm struggling with the default temperatures and voltages of my CPU.

During looking at the desktop of the Windows (both 10 and 11), in Ryzen Master and other monitoring SW I can see that CPU Voltage is around 1.4/1.45 V (set to "Auto") and CPU temperature reaches 55/60 °C.

After performing few tests using AMD Ryzen Master, I've discovered that the stable voltage of my CPU is around 1.21 V, with all cores limited to 4.5 GHz.

And here is my quetion. If my CPU behaves as normal 5800X (it is not faulty) and those CPUs  are just that "hot", is there any way of setting specific values by UEFI to define the CPU behavior that will be caped at 4.5 GHz and 1.21V but will drop both voltage and clocks when it does not need them?

Since 2021 I'm using Ryzen Master at Windows Startup, and manually set voltage to 1.216V and core clocks to 4.5 GHz, but it requires to do that at each startup of the Windows.

Thank you in advance.

PC Spec:

CPU: Ryzen 7 5800X

MOBO: MSI MAG B550 Tomahawk

RAM: 2x8GB Patriot Viper Blackout 3600MHz

PSU: be quiet! Straight Power 11 650W 80+ Platinum

GPU: MSI RTX 4070 Gaming X Trio

CPU Cooler: be quiet! Dark Rock Pro 4 (120 mm/135 mm)

Case: be quiet! Silent Base 802 in "airflow" configuraiton with 3 Silent Wings (low RPM version but with curves defined in BIOS) at the front and one at the back

What you describe is normal operation, why do you feel this is "struggling"?

Temperatures are perfect, no adjustment required.

Voltages are likely higher due to increased boost speed attained because temp is so good.

If you want to reduce voltages you can simply adjust Curve Optimizer to a negative value, anywhere from 0 to -30 is possible, likely stability will limit you to -20 to -25.

If you want to restrict both voltage and operating frequency, look to use ECO mode and set a 65W TDP in BIOS.

I would like to limit the noise from the PC.

I've tried to set Cuvre Optimizer to -20 mV but it was to much (I think) because. I will try and see, what ECO Mode will change, but my question was rather related to the method of transfering the Ryzen Master settings to BIOS parameters to "fix" them and to remove the need of changing parameters during each Windows startup.

Then it sounds like you should adjust the fan curves or pick a different preset, "Silent" instead of "Normal" for example.

If 55/60°C is the maximum temperature reached, there is no reason the PC fans/cooling should be making a lot of noise.

I would explain the issue in a more simple way.

I'm not looking for a tip related to changing the fan curves because I have done many adjustments and I see that it is not related to the fans and their speeds.

I would like to now how to transfer settings from Ryzen Master to BIOS via UEFI in that way that CPU will do what I want...

And as I said previously, I would like to limit CPU clocks to 4.5 GHz and voltage for all cores to 1.21 V and set everything to drop the clocks and voltages when it is not needed. Ryzen Master does that but I have to use it during each startup of the PC and it is not acceptable anymore for me.

CPU is cooled by Dark Rock Pro 4 so it is more than enought cooler as well as the set of 4 Silent Wings inside the case - there is no problem with cooling devices setup, just with limiting CPU, and I would like to know what I have to modify to set BIOS exactly like mentioned before.

Ryzen Master by default saves certain settings to BIOS. Open Ryzen Master. Open Settings. Check the toggle for PBO and CO that both are ON. These defaults save settings to BIOS. So if yours is not, make sure you are on the latest version.

Other custom settings can be saved to a Ryzen Master Profile, so they can easily be loaded on restart by simply loading the Profile. But you state you do not want to have to use Ryzen Master after every reboot.

So any of the settings in Ryzen Master can be easily set in the motherboard BIOS, typically under Settings and AMD Overclocking section. Then you don't even need Ryzen Master.

As to doing exactly as you asked, your best option for restricting the CPU frequency and voltage is to use ECO mode to set a reduced TDP such as 65W instead of the factory 105W. Alternately you can play around with Curve Optimizer and PPT limits to achieve your desired results.
