Turbo Limits doubts

[noadria]

Hi, I started using "Throttle Stop" for my I7-10700K processor and it was a total change of temperatures and consumptions, I am happy with the change and I am still investigating the software to continue optimizing, I thank the creator of the software.

I have some questions regarding the CPU turbo boost.

With this configuration, I get my CPU in games to stabilize at 4300 Mhz, that is a speed that maintains good temperatures and performance. But I have noticed that there are moments when minimizing or maximizing the game, or opening other software or windows explorer the speed rises to 4700 Mhz. This happens in a short period of time.
I understand that this is related to the boost, but doesn't the boost also exist at the moment of reaching 4300 Mhz ? (3.8 Ghz base - 5.1 Ghz Boost).
After reading several similar posts, I know that this has something to do with the "turbo ratio limit" option of the cores, but what would I have to change so that this does not happen? or is it something that can not be changed?

Is it ok to use 4300 Mhz maximum on a CPU like this? Without "Throttle Stop" the CPU in games reaches 4700 Mhz and I reach temperatures of 70-80 C, and with "Throttle Stop" in 4300 Mhz I don't exceed 60 C.

Attached screenshots of the configuration and in game. (I couldn't capture right at 4700 Mhz in game, but it was more than 4300 Mhz)

Thanks.

Your Intel CPU is rated to be able to run up to 100°C. You can use ThrottleStop to reduce its performance or you can use ThrottleStop to maximize its performance. The choice is yours.

When the PL1 turbo power limit is left at the 125W default value, your CPU will power limit throttle during any demanding situation. Is that what you want? I set my 10th Gen CPU to 300W for both PL1 and PL2.

I prefer performance and I prefer a steady CPU speed. You can change the turbo ratio limits to whatever you like. Set them all to 47 if you want your CPU to run at a steady 4700 MHz. My similar 10850K has the turbo ratios set to 50. Press the All Core 50 button in the FIVR window if you want to do the same. As long as your cooling is good, these CPUs can run comfortably at this speed.

I would also use the Windows High Performance power plan. Having a fast CPU when plugged in is not a bad thing. More speed and less latency can only improve your gaming experience.

Set Speed Shift Max back to the recommended value. It is better to adjust the turbo ratios in the FIVR window to control the CPU speed.

I configured it as you told me, I leave some screenshots.

I did the stability test of "AIDA64" and I had maximum temperatures of 78º and 166.7 W.

What is the difference of a 4700 Mhz speed with 125W or 300W TPL?

I know that the processor has a maximum temperature of 100ºC, but it always seemed to me that having it at 80ºC or more was too much for gaming.

Another question, with the previous configuration, why did it reach 4700 Mhz for instants being limited by SpeedShift?

Now I'm going to try limiting it only with FIVR to see if that doesn't happen again.

Thanks for your answer.

I always used intel XTU to limit the multipliers.

(I have nothing against Throttlestop though)

With that multiplier limitation, do you get the boost? or what is the "turbo boost short power"?
They should always run at 2800 Mhz.

I had no more turbo boost, it will lock the max speed of each core so it will do as you want.

With intel XTU it's easy to limit the speed per core.

Your CPU can not maintain 4700 MHz indefinitely if the long term turbo power limit (PL1) is set to the default 125W. If you try to do a 10 minute Cinebench test at 125W, after a while your CPU will slow down so it does not exceed 125W. That is why I set both power limits to 300W. This avoids any unnecessary power limit throttling. The 125W number is mostly for Intel marketing purposes.

It is likely that Windows is writing its own values to the Speed Shift control register. Having ThrottleStop and Windows both writing different values to the same CPU register is not a good situation for the CPU. Adjusting the turbo ratios is a much more reliable way to manage the maximum CPU speed. Windows does not seem to interfere with the turbo ratio values.

having it at 80ºC or more was too much for gaming.

80°C or 90°C or 99°C are all safe operating temperatures according to Intel. If these temperatures were not safe, Intel would have reduced the thermal throttling temperature years ago. Pretty much all of the Core i CPUs released during the last 15 years use a default 100°C thermal throttling temperature. Some 1st Gen Xeons were 101°C and many 3rd Gen were as high as 105°C.

If you prefer less heat, it is OK to reduce your CPU speed. You should be able to create a separate gaming profile in ThrottleStop with lower turbo ratios if you like. I like max speed until the flames start shooting out the side of my computer.

I always used intel XTU

XTU uses 10 times as much memory and consumes 10 times as many CPU cycles compared to ThrottleStop. When running any benchmark, ThrottleStop will always give better performance. ThrottleStop properly applies all of its settings after resuming from sleep. XTU does not always do this. XTU has had this consistency problem for many years.

Perfect, then I'll start limiting it this way.
To summarize, I set the PL1 and PL2 to 300W to avoid power limit throttling regardless of whether I limit the speed or not. And then I can regulate the speed according to the temperatures.

I have an air cooler for the CPU, it starts running at 80-100% from 70ºC, can I leave them like that or is it better to run at higher speed at lower temperature?

Thanks

That makes the most sense to me. Intel created piles of overlapping throttling methods. I can just imagine all of the separate teams that brain stormed new ways to make users lives miserable. I believe in keeping things as simple as possible.

You can do whatever you like with your CPU. If slowing the CPU down creates less heat and less fan noise and that makes you happy then it is OK to do that. That is the best thing about ThrottleStop, it puts users in control so you can decide how you want to run your CPU.
