hey. I really want to get rid of any limits on my pc. Hw info show max vr voltage iccmax pl4 always ,,yes,, even on desktop.
Pc specs:
Asrock Z790 PRO RS
I5 14600KF
Temps are normal(max 73C) so i really want to increase perfomance.
I was trying to fix a problem with throttlestop, but 14 gen is not supported. Any ideas how to fix it via bios?

I'd say start with updating the HWInfo64 app. It's at revision 8.12 now, perhaps there was some changes made.

Post screenshots of the main ThrottleStop window, the FIVR and TPL windows. Open Limit Reasons when your computer is throttling. ThrottleStop cannot solve every possible throttling problem but it can diagnose and solve quite a few problems on 14th Gen CPUs.

Here is a guy that recently scored over 40K in Cinebench R23 with his 14900HX while using ThrottleStop. That score would have been good enough for third place if he had entered it into HWBot.

edp other was on red while benching. when i unlock adjustable voltage on cpu core and cpu p cache the iccmax was set on 511.75 and edp other dissapeared...

as u see while benching and enabling adjustable vattage edp other dissapeared. i was trying to change ICCMAX (on asrock bios its called ,,cpu core current limit,,) in bios to max value but its not working, still have these limits...
 
edp other dissapeared
Thanks for confirming that ThrottleStop is working correctly on your 14th Gen CPU and that ThrottleStop was able to fix your EDP throttling problem. It is the BIOS that is not setting your CPU up correctly.

The other problem I see is your BIOS has enabled Intel Undervolt Protection. That feature will prevent you from using software like ThrottleStop to adjust your CPU voltage while in Windows. There might be an option in the BIOS to disable Undervolt Protection. Some recent BIOS updates can prevent one from disabling UVP no matter how this is set in the BIOS.

Your screenshot covered up the main ThrottleStop window so I cannot confirm if your CPU is running at full speed or not. To run the 54 multiplier, try checking the Overclock box in the FIVR window. Also check the Speed Shift box in the TPL window and set Speed Shift Max to the suggested value.
 
Ring is limited to cpu v-core unless has it's own setting
""vr voltage iccmax pl4 always ,,yes,,""

Ring ratio is too high for the available design current. It goes away when v-core ramps up during the benchmark. Ring throttles at idle also. It's normal.

More performance would utilize all core multipliers and increased LLC, v-core set to auto. Maybe 5.4ghz P-core and 3.8ghz to 4.0ghz E-cores. Ring Ratio starting at 4.6ghz.

Oh, and 24K+ is essentially where a 14600K should be at stock. Give or take depending on the memory settings. So no worries there.

i disabled a undervolt protection in BIOS and activated speedshift

give me moment and im gonna set overclock and then i will see if it go to 54x

oh and i set all cores to 54 on turbo group

even when its 54 multiplier on all cores it still goes to 5300mhz max...

Memory was default on 5400mhz, but with xmp its 6400

On my Z790 Riptide, with a 14600KF@ 5,5GHz I run:

"OC Tweaker" and under "Power Delivery Profile" @ BIOS Default

CPU Configuration:
- CPU P-Core Ratio/Max Ratio set at "55"
- CPU Cache Ratio "48"
- UnderVolt Protection "Disabled"
- Intel Speedstep/Turbo Boost Tech "Enabled"
- Speed Shift Tech "Disabled"
- Intel Dynamic Tuning "Disabled"
- Intel TVB Ratio/Voltage "Disabled"
- TJ Max/ FTT "100C"
- Long/Short Duration Power Limet "200"
- Long Duration Maintained "56"
- CPU Core Unlimited Current Limit "Disabled"
- IA/GT CEP "Disabled"
- Rest "Auto/stock"

Under Voltage Config:
- Voltage mode "OC mode"
- CPU core/Cache LLC "Level 4"
- VDDQ Volt "1.350"
- IA AC Loadline "0.24" (If CPU runds stable at 5,5GHz with this setting, you can bump up the P-Core multiplier, when unstable you can raise this or dail back the multi).
- IA DC Loadline "1.02"
- Rest "Auto/stock"

And CPU C State "Disabled"

Not sure if you got the same layout/settings as my board, but this config makes my CPU run 5.5GHz under 100% load, no throttle, good temps, stable running Prime 95 for hours. CPU just dont like anything over 5.5 GHz...
 
even when its 54 multiplier on all cores it still goes to 5300mhz max...
The 54 multiplier is overclocking. Try checking the Overclock box in the FIVR window.

If that does not unlock the 54 multiplier, try checking the MMIO Lock box which is near the top right of the TPL window.

If you still cannot access the 54 multiplier then I guess you will have to set the 54 multiplier in the BIOS.
 
Now i see my clocks running to 54x after MMIO lock enabling :) gonna run some tests

teach me master, i want more :D
 
It was fun while it lasted. Do you remember changing something?

I would set Speed Shift Max to the max, 255.

Try doing a sleep resume cycle. That might unlock something.

I would use the BIOS to set the max multiplier.
 
Is it possible to do everything in bios? Im going to sleep, gonna do some tests later, thank u so much :) i will respond later

I reset iccmax in bios cuz it didnt work,
 
Any time you make a change in the BIOS, you should delete the ThrottleStop.INI configuration file before running ThrottleStop. That way ThrottleStop will be able to read how the CPU is setup without trying to apply any settings that it was previously using.

It was sort of working, with the help of ThrottleStop. I would set IccMax in the BIOS back to the way it was when your computer was running without any throttling at the 54 multiplier.

The BIOS has the ability to set a maximum multiplier and it can lock this setting. You cannot use ThrottleStop to increase the maximum multiplier if this setting has been locked by the BIOS.

I would set the 55 multiplier in the BIOS, boot up and use HWiNFO or CPU-Z to confirm that your CPU is actually using the 55 multiplier. If your computer is running at the 55 multiplier before you start ThrottleStop, it should continue running at full speed after you start ThrottleStop. Just remember to delete the previous .INI configuration file so ThrottleStop does not try and apply any previous settings that you saved to ThrottleStop.

Setting everything in the BIOS is always best. In your situation, the BIOS does not seem to be setting the CPU up correctly. That is what is causing EDP throttling of the RING. Unless you can find a BIOS version that is not broken, you are forced to use ThrottleStop if you want to fix the RING throttling problem.

Some manufacturers do this type of throttling deliberately. Throttling the ring bus speed equal to the base frequency of the CPU is a cheap way to improve stability. Performance will decrease when the ring is being throttled like this but for some tasks, the drop in performance might not be noticed. The performance impact will depend on what games or benchmarks you are running.

hey. sorry im back and fixed a throttlestop problem. i just set p core to 55 and its working :D

on stock bios version there was no limits at all... so i think its intel fault cuz i update bios to the newest version.

56x hehe

1728758382667.png


i tried 57 but the program crash so i think its a limit with default voltage, what do i need to change?

changed e cores to 42x, 30min bench done succesfully:

temps are really nice too (room temp 23C):
