[SOLVED] How do I limit the turbo frequency in BIOS? 5800X and ROG STRIX B550i

[guts_]

Hello,

I have recently set up a PC and got a bit into the overclock/undervolt world. I discovered CTR for Ryzen processors, but I don't like that it is the program that sets the CPU values, and I would like to take the values it throws me to the BIOS, but.... I don't know how to limit the turbo frequency of the processor.

I have a 5800X, and I would like to be able to limit the frequency to 4600MHz, do you know if it is possible to do this from the BIOS? After reading a lot, I finally resort to ask, because I can't find a solution.

My idea is to set the PPT, EDC and TDC values, use the Curve optimizer, limit a little the voltage and frequency. I have already done stability tests, but I don't know how to limit the turbo frequency from the BIOS...

My motherboard is an ASUS ROG STRIX B500i.

Thank you very much in advance!

Greetings

There is an option in the Curve Optimizer portion to add an offset to the maximum turbo frequency, but I don't know if this accepts negative values. Otherwise you'd have to adjust the PPT limit (if that's a thing).

Yes, I have seen that option, but it only allows to set positive values of 25 by 25 up to a certain limit, but not negative values.

I have tried adjusting the PPT, but at 95W it still goes to 4850MHz for several cores.

I said that I have read a lot before asking, and I have not seen anything, so I understand that it will not be possible? I don't know how the CTR application will do it, though.

Yes, limiting the maximum turbo boost frequency directly doesn't seem possible. However, I don't think this is a problem per se.

The maximum turbo boost frequency only applies to light workloads that uses 1-2 cores. With regards to power consumption, not only does this not use a whole lot of power (maybe an additional 10-15W over idle), but with regards to overall power consumption, it's actually beneficial to let those cores run as fast as they can so they can return to idle sooner.

Why do you want to limit the boost speeds? Heat issues? Maybe you need a different solution than reducing the boost speeds.

CTR actually does a fantastic job, and as 1usmus has pointed out, mostly gives better results the PBO+ CO.

It's actually really easy to change the speed in the profiles on CTR. You simply click on the clockspeed box, and manually enter the desired speed. Save the profile, and bingo, away you go.

I love CTR just for the ease of use. The PX profile gives brilliant results, with my 5600x hitting 4.9ghz on a couple of cores, and anywhere from 4.75ghz - 4.85ghz all core, depending on the specific task, but in gaming, never going beyond about 80w on the CPU.

I have a 5800x and with PPT, EDC and TDC and Curve optimizer I have 70 degree spikes when I open an application (e.g. LoL) and 1.5v, and I don't like it.

In CTR I have it limited to 4600 and 1.25v and it doesn't go over 60 when I open applications, and the multicore doesn't go over 80. That's what I want, but configured from the BIOS.

I've read a lot that those voltage spikes and temperatures are normal on the 5800X because of how it's built, but I don't know, I don't like it.

77C is well under max, for that CPU. It is nothing to worry about. You could maybe try some voltage offsets, in the bios, to reduce temps a bit, but not really necessary.

Yes, that's what I've read, that this processor is like that, with crazy temperature spikes and such, not to worry. I will follow your advice, thank you very much

I run a 5800x myself, with a Vetroo V5 cooler. I just set PBO and leave it alone.

Ah, I get ya!

What cooler are you running? Temps seem on the high side even with 4.6ghz and 1,25v. What are you using to test for temps?

Scythe FUMA 2 in a NR200. It's a ITX build.

Im using Prime95 or Cinebench R23. When I play, temperatures usually hover around 60 degrees.
