Question Intel i9-13900K throttling to .78

[Teener]

Hello!

I'll start by posting my specs:
CPU: Intel i9-13900k @ 3GHz with a Corsair H100i liquid cooler
GPU: ASUS ROG 4070ti
Motherboard: Gigabyte Z790 Aorus Elite
PSU: Corsair RM1000x 1000W 80+ Gold
OS: Windows 11


I built this PC back in March this year and it has ran smoothly so far. My problem is that my PC is running very slow all of a sudden. A 60fps video will stutter heavily and any game I run averages ~20fps. Task Manager reads that my CPU is stuck at .78GHz.

So far I have:

1. Updated my bios and reset my settings to default.
2. Updated all of my drivers.
3. Followed similar threads using ThrottleStop, but none have resolved my issues so far.

I'll post my ThrottleStop and HWMonitor screenshots like I've seen in similar threads before posting this one.

Thanks in advance for any help you can provide!

to have a look what the problem could be:
run userbenchmark.com and post the http link of your result, e.g. https://www.userbenchmark.com/UserRun/28977730

If not done like this:
Reset the BIOS by jumper clrCMOS or JBAT or similar (eventually you will have to set the boot priority correctly after that)

check windows integrity
open the command prompt as administrator and type DISM /Online /Cleanup-Image /RestoreHealth

check the memory by running memtest.org usb autoinstaller (bootable USB flash drive)


check the hard drives for errors with its manufacturer´s tool and if available, update the firmware

use ddu uninstaller and reinstall the latest graphics driver

Here's the benchmark https://www.userbenchmark.com/UserRun/64417656 and I'm currently checking windows integrity.

uninstall all tuning, OC or sensing software and restart windows

check if energy management is set to balanced
check the balanced profile, eventually it´s set to a lower procentage?

@Teener
EDP OTHER throttling that ThrottleStop is reporting is typically caused by one of the current limits being set too low. I am not sure if ThrottleStop has access to the limit that is set too low but here are some things to try.

Check the MMIO Lock box which is near the top right corner of the TPL window. Set Power Limit 4 to the maximum value which is usually 1023.

In the FIVR window check the Unlock Adjustable Voltage box and make sure that IccMax is set to the max, 511.75, for both the P core and the P cache.

If none of these changes make any difference then search your BIOS for any setting that is current limit related. Some current limit somewhere is likely set to 0 which is causing constant EDP throttling. Make sure you have installed the most recent BIOS version. This issue was likely fixed in the latest BIOS. Reset all BIOS settings to their default values.

If you cannot solve this problem then you will probably need to replace your motherboard.

Edit - I just noticed that the same thing happened to a completely different Gigabyte board where the main current limit somehow got set to only 1.00 Amp. This caused the same EDP throttling problem that you have.

I did a clean boot and that seems to have resolve the throttling issue.

However, ThrottleStop alternates red/yellow edp other under RING and just yellow on GPU.

Is this something to be concerned about or should I not worry about it?

Edit: I just read in another thread with my current issue and uWebb says: "You can create a lot of problems if you change the motherboard or the CPU and you do not reinstall Windows."
I have done both of these without reinstalling windows so I will do that now and see what happens.

ThrottleStop alternates red/yellow edp other under RING

This is done deliberately by some Z690 and Z790 motherboards. This throttling forces the ring to run at the base frequency instead of the turbo frequency. This improves stability but it reduces maximum performance.

Try using ThrottleStop to set IccMax for both the P core and the P cache to the max, 511.75.

Did you update to the latest BIOS version?

Looks like that was the case! Thank you so much!! I have updated my BIOS to the latest version.

Reposting so the solutions will be under one post if another user has the same issue.
