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

system specs-
i9 14900k turbo 6GHZ
1 TB NVME M.2 SSD
1000 watt psu
32 GB of ram Team T-force delta 2x 16 gb
windows 11 home
MSI geforce RTX 5070 shadow 2x oc 12gb

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)

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.

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
