14900k high voltage

[nickdog]

so about 2 and a half weeks ago i bought a new gaming pc from cyberpower but im having a problem with 14900k raising to 1.5volts i was not aware that this was an issue with these chips until i started moinitoring the volts it did seem quite high even for me im not all experienced in this bios stuff let alone feel comfortable changing and messing with undervolt and bios settings started messing around with LLC mode the default was complete crap the volts always stayed the same and never went down it seem stable kinda at mode 10 with adaptive offset of -0.090 at -0.100 forza wouldnt launch fully at this mode i get 180 fps in forza but it spikes up n down somtimes randomly high i have this MSI Pro Z790-P i look in throttle stop and i see EDP other flashing red under core and RING heres a few pictures of my bios i already tried adaptive mode alone spikes up in volts like crazy it came overclocked with ram profile honestly wish i did reasearch about this chip before buying it i just want to be able to have a stable sstem and gaming performance without overstressing the cpu i really need help to stop this throttling please any help greatly appreciated i dont want to kill my cpu i cant stop stressing over this thank you!
for some reason when i changed ICCmax from 307 to 400 i got crashes on black ops 6 and some back screens at times i really need some expert advice

14900k raising to 1.5volts

The default voltage for many 13th and 14th Gen processors tends to be high. Intel extended the warranty from 3 to 5 years to help cover any failures.

The ThrottleStop FIVR window shows that you still have Windows core isolation memory integrity or something else enabled that is using Virtualization Based Security. Many items in the FIVR window like voltage and IccMax control will not work when VBS is enabled. Run msinfo32 and see what it reports for Virtualization Based Security. To fully disable this, follow the links in my signature. Disable Intel Virtualization Tech in the BIOS.

After VBS is disabled, reboot and delete the ThrottleStop.INI configuration file before running ThrottleStop. Post an updated screenshot of the FIVR window. Use ThrottleStop 9.7.3. The All Core section of the FIVR window should not be showing negative numbers. That is a good sign that ThrottleStop is being blocked from reading registers within your CPU.

If maximum security is important to you, leave VBS enabled. If playing games smoothly is more important to you, disabling VBS is a good place to start tweaking.

To better control the power limits, remove from auto and manually set short//long term to 253w.

All the boosting will run the cpu to its max thermal limit usually closer to 300w +/-.

This is all actuated by thermal velocity boost (TVB)

 

[unclewebb]

manually set short//long term to 253w

His ThrottleStop screenshot shows that the PL1 and PL2 turbo power limits are both set to 253 Watts. The BIOS shows the same thing.

Limiting the maximum turbo speed when the CPU is lightly loaded is one way to reduce the maximum voltage. Sacrificing a few hundred MHz will barely be noticed and can help drop the max voltage significantly.

Update the BIOS, which should give you a new Intel Boost name that is 100% compliant with Intel CPUs. You are seeing 1.5V because of the 6 Ghz Single-Core Turbo.

I would suggest that it would a worthwhile effort to learn how to learn how to set up your BIOS properly.
Only a few things would need to be modified. It take some trial and error to find your system's optimal settings.
You're just asking for this leaving everything on auto.

No offense to the OP, but I honestly believe much if not most of the 14th gen fiasco was due to this type of situation.
I would put some blame Cyberpower for being lazy and sending it out like this.
A high end system may take more effort to operate, just as high performance automobile might more require tuning and maintenance.

Read up, and get it under control before it becomes a more serious problem. Good luck.

It always says that. My TUF board does the same thing.

14900K is the only cpu from 14th gen using TVB.

Setting the limit to 253w manually will not change the reported clocks = 6ghz 2 cores light load, which will probably report over 1.45v to 1.5v any ways because thats what it takes to reach that frequency.

The all core 5.7ghz clocks will just run away with the auto power limits, will see 100c quite often.

If it where an Asus like mine, you'd simply just disable the Asus MCE (multi-core enhancement) and the cpu will ignore the boosted auto TVB setting.

A 14900K operates a bit differently than 14700K and lower due to TVB.

 

[unclewebb]

The all core 5.7ghz clocks will just run away with the auto power limits, will see 100c quite often.

The Auto setting in the BIOS version that he is using is setting the turbo limits to the correct default values, 253W for PL1 and PL2. ThrottleStop confirms that the CPU is using those values. In this case, setting the turbo power limits manually to 253W is not going to make any difference. If switching to an all core clocks setting also changes the power limits then locking them to 253W would be a good idea.

Not using 6.0 GHz when 1 or 2 cores are active would be the easiest way to limit the max voltage.

Its a 6ghz boxed processor. How would that work? Manually set cpu multiplier.

You can run an Intel CPU at whatever speed you like. I have a mobile 14900HX which at default specs tries to run the two fastest cores at the 58 multiplier when 1 or 2 cores are active. It takes a lot of additional voltage to get a CPU core stable at 5800 MHz compared to the default 5200 MHz which this CPU uses when more than 2 cores are active. When lightly loaded surfing the internet, no one is ever going to notice a performance difference between those two speeds. Now there is no need to use such high voltages.

You can either slow the CPU down in the BIOS or you can use ThrottleStop to accomplish the same thing. The advantage of using ThrottleStop is you can switch profiles and run your CPU at different speeds without having to reboot.

Default Turbo Groups

All Turbo Groups Limited to 52 X

A good compromise for a 14900K might be 54X or 55X. You could run this speed comfortably without needing the peak voltage that 60X usually needs.

OK, an HX on a limited cooling solution can use all the help it could get. I admit that.

However, nobody needs TS with appropriate motherboard settings in bios. I mean its useful, but Im not here blowing smoke.

The power limits are lifted when set auto.

See in his screen shot. TVB box is ticked. Multiplier boost ratios are set to 80!!

thanks for your reply i disabled VBS and and downloaded latest version of throttlestop before i only had version 9.7 not 9.7.3 dont know if that mattered heres new screenshot of FIVR i can retake it if you cant see it im getting a usb flash drive tommorow would it be worth updating to latest bios ive never done so and i get real nervous about those things also why does it say i have a system agent static voltage


those are the reults after playing eso also have process lasso running to help also forza just crashes now when trying to load in get massive fps drop which happens in the loading screen and the game crashes to desktop after disabling VBS fully and redownloading throttlestop fixed the forza crash by adjusting both iicmax 307 under cpu p and cpu core in throttlestop also what do these multipliers mean under the vid how do i know if im receiving maximum perforomance

 

[unclewebb]

Those cell phone screenshots are hard to see. Try using the Windows Snipping Tool when taking screenshots.

Use HWiNFO for a second opinion. What does HWiNFO show for the max VCore voltage? What HWMonitor is reporting for the max CPU voltage looks great.

The ThrottleStop Turbo Groups section shows that you are trying to run all of the P cores at the 60 multiplier. This is considered to be overclocking. If you want to overclock your CPU then check the Overclock box in the FIVR window. I am not sure how to do this in your BIOS. If you are trying to use a BIOS all core setting that is supposed to run all cores at the 60 multiplier then based on your screenshots, that BIOS feature is not setting your CPU up correctly.

At the moment your two best cores are able to use the 60 multiplier but it looks like the rest are being limited to the 57 multiplier. These are likely the default values for your CPU when not overclocking.

Most owners of desktop computers prefer doing all of their adjustments in the BIOS. You should be able to set higher IccMax values in the BIOS. In ThrottleStop I set IccMax to the max, 511.75, for the CPU Core, P Cache, Intel GPU and iGPU Unslice. I realize you have a KF series CPU which does not have an Intel GPU. KF and K processors are physically the same. The Intel GPU is still physically there. Just access to it has been blocked off and disabled in the KF processors. That is why I would still set the IccMax values to the max for the Intel GPU and iGPU Unslice even on KF processors.

why does it say i have a system agent static voltage

Many desktop computers set a fixed voltage for the System Agent. Most laptops have this set to Adaptive with the Voltage slider and Voltage column in the monitoring table both set to Default.

what do these multipliers mean under the vid

What multipliers are you talking about? The multipliers in the Cache Ratio section allow you to control the min and max P cache multipliers.

The power limits are lifted when set auto.

I am sure that is true on your Asus motherboard. That is not what is happening on his MSI motherboard.

Multiplier boost ratios are set to 80!!

He originally had Intel Virtualization Tech Enabled in the BIOS. That blocks monitoring software from correctly reading these values from the CPU. With Virtualization Tech disabled, ThrottleStop is reading the correct 60 multiplier that the BIOS has set the Turbo Groups to. ThrottleStop is just a tool. I agree that most users with a full featured BIOS on their desktop computers do not need to use it. If it can help troubleshoot issues where the BIOS is not working correctly then why not use it? He has already fixed the crashes he was having when trying to run Forza.

how do i know if im receiving maximum performance

Try running Cinebench R23.

Cinebench R23

Cinebench is the perfect tool to compare CPU and graphics performance across various systems and platforms

www.techspot.com

Cinebench is a good quick testing tool. When your CPU is fully loaded, the default 253W turbo power limits are likely going to cause your CPU to slow down due to power limit throttling. Open ThrottleStop Limit Reasons and watch for PL1 or PL2 lighting up red under the CORE column. There could also be other things lighting up red indicating other problems. You might see thermal throttling if your cooling is not adequate or perhaps there will be problems with the voltage regulators.

 

[ShrimpBrime]

Yes old friend. On MSI you simply set PL1 and PL2 manually, not set auto. 14900K TVB over-rides the 253w setting. This is how I have already demonstrated several times on this forum. Across at least 2 MSI boards and 2 Asus boards of the LGA 1700 desktop systems with several different processors. The proceedure is the same for both MSI and Asus.

Set PL1 and PL2 to the wattage you want to dissipate as heat. Because a processor is 100% effecient at changing an electrical current energy (EDC) to a thermal energy. (What the heat sink can handle).

But by all means, keep the under-volt craze alive!!

 

[nickdog]

thank you i used the snipping tool instead hopefully these pics are better the txt below is log of trottlestop in the downloads if that helps btw ever since i downloaded hw info the errors in limits in TS vanished im still getting fps drops bad though does it matter if cpu tuning cooler is sset to msi performance which is 253W or intel default which is 253 w theres also msi unlimited performance 4098w i keep seeing Ecores go all the way red in that screenshot hwinfo is this suppose to be happening

what should i set Pl1 and PL2 in bios? does it matter what the cpu cooling tuner is set to

 

[ShrimpBrime]

what should i set Pl1 and PL2 in bios? does it matter what the cpu cooling tuner is set to

Cpu cooling tuner on air if air, water if water.

PL1 and 2 set to 253w (or something lower if you want like 220w) and it should never exceed that no matter what the v-core does. LLC on MSI level 4 should be OK. 5 will droop more at load and 3 will droop less. V-core leave auto. (No offsets)

If you use the cpu with everything default and see reports of 1.50v, its not uncommon for 6ghz cores. Just remember 2 cores at 6ghz isn't breaching 253w. So even if you set 220w PL1/2, you should still see 6ghz boosting light loads. All core loads will be restricted to 220w however. (220w is just a random number I picked. You could try 235w or w/e.)

 

[unclewebb]

ever since i downloaded hw info the errors in limits in TS vanished

If HWiNFO is running on your computer, it will clear the Limit Reasons data out of the CPU so ThrottleStop will not be able to correctly report this. You can either use HWiNFO to view the limit reasons data or you can use ThrottleStop. You cannot use both programs at the same time due to the way HWiNFO works. If HWiNFO is running on your computer, Limit Reasons will show this helpful reminder when it first opens up.

i used the snipping tool

That looks so much better. Thanks. My eyes appreciate it!

i keep seeing Ecores go all the way red in that screenshot hwinfo is this suppose to be happening

I do not know what the red bars mean in HWiNFO.

I do know that originally you were trying to use the 60 multiplier on all cores and now you have reduced that to 46. That seems kind of drastic. It will be a big loss in overall performance. Running the P cores at the same speed as the E cores or running them slower then the E cores is usually not a good idea.

Originally you had a problem with voltage but I am not sure if you still have that problem or not because you slowed the CPU down so much. The log file shows that there are no voltage issues when you are running your CPU at only 4600 MHz or 4000 MHz.

Let me know if your goals have changed. Open the HWiNFO sensors window to see what VCore voltage your CPU is using. Did you try running Cinebench yet?

 

[nickdog]

thanks for your reply i was able to pass single core cpu test bnut when i hit multicore the program freezes and i have to ctrl alt del and end task to get cinchebench to close heres so pictures will it ruin my pcs if i use msi perfomance setting for cpu tuning cooler 4098w the other 2 are another msi settings and intel setting for 253w does it matter what you choose would i get more performance with 4098w instead i have 360mm AIO cyberpower

 

[unclewebb]

when i hit multicore the program freezes

If Cinebench crashes then the voltage settings you are using are not stable. HWiNFO reporting WHEA errors is another sign of a computer that is not 100% stable. You should never be seeing WHEA errors. Your CPU likely needs more voltage. Reduce your undervolt and see if these errors go away.

What speed are you running your CPU at now? Default appears to be 6000 MHz for the two fastest P cores and 5700 MHz for the other 6 P cores.

Setting the turbo power limits to 4096 Watts will not cause your CPU to use the full 4096 Watts, ever. This max setting simply tells the CPU to never power limit throttle. You only need to go beyond 253W if you have good cooling and this setting is causing power limit throttling and limiting your performance. Most games do not need 253W. If that is what you mostly use your computer for then there is no reason to increase the turbo power limits. No one in a forum can guarantee what settings will be 100% safe for your CPU. If you are worried about safety, leave the power limit settings at default values.

 

[nickdog]

i undervolted some it made it through multi core cinchbench i sitll see few errors though i have gameboost off in bios cpu creator genuine do you think that would matter im running them at 5.7 the p-cores

 

[unclewebb]

Do a Google search for,

CPU TLB Errors HWiNFO

Those kind of errors are not good. Keep adjusting the voltage and see if you can fix that problem.

do you think that would matter

I do not know what settings in your BIOS are good or bad.

 

[nickdog]

seems i tend to get more stable fps in games with HT turned off strange i still have some latency and ms in alot of games it still drops somewhat but not quite as bad it seems

 

[unclewebb]

Have you tried using the Windows High Performance power plan? You can use ThrottleStop to access this power plan if you do not see it in the Windows Power Options.

Some users get lower latency and smoother gaming performance after they disable the C states in the BIOS. Give that a try.

yes i tried that i disabled C-state aswell what about lite load calibration control auto or use that instead of lite load mode im on cpu lite load mode 10 and lite load calibration control auto with an adaptive offset of -0.041
