V/F Point window with messed up frequencies

[rcllfv]

Hi, I was trying to undervolt my laptop, a Lenovo Legion Pro 7i with a 14900HX CPU and following some guides but I noticed that my V/F point window has very different frequency values than what the guides show (all 12000 mhz) and I can't change it either, I tried using a previous version for the simpler mv Boost function and it also showed a different frequency different than 800mhz. I'd like to know what could I have possibly messed up on my laptop for it to show such different values. It shows the same for both core and cache.

If you have Windows core isolation memory integrity or anything else VBS related enabled, ThrottleStop will not be able to read or write information to the voltage control registers.

Follow the two links in my signature and get VBS disabled. Exit ThrottleStop, delete the ThrottleStop.INI configuration file, reboot and post an updated FIVR screenshot.

I don't know when it changed because I'm sure Throttlestop worked fine for me before, but I got it working now, disabling VBS through command prompt fixed it.

Some users have reported that Windows Update can re-enable core isolation memory integrity. It is a good idea to have a look in the FIVR window every once in a while, especially after a Windows update, to make sure everything is still working OK.

Edit - I just posted some useful screenshots of the settings I use for my 14900HX.

Will the V/F curve of a successful operation be displayed in the CPU voltage deviation of the FIVR interface?

I am a newbie in this area and I don't understand many functions.Please, can someone help me?Below are some parameters I adjusted based on my study.I made sure I had VBS turned off and the voltage offset function was working in the software.In addition, I changed Legacy to Selection in BIOS...

Thanks, does the mV boost apply right away after I tick the boxes? I'm getting BSOD right away after applying the offset even at 100 mV (I'm matching it to the negative offset on overall voltage), I suspect it might not be applying the mV boost

Are you entering a negative value for V/F Point 1? That should be a positive value. Do not enter the + sign and definitely do not enter a - sign for V/F Point 1.

If "Use Core V/F Offsets" is checked and you press the Apply button, the V/F offset value will be applied to the CPU immediately. I am using the same 150 value for both the core and the cache.

You should adjust V/F Point 1 and save that value before adjusting the CPU Core and CPU P Cache voltage offsets in the FIVR window. Adding V/F point voltage to the CPU should not be causing it to crash.

Yes, positive value for mV boost and a negative value for the voltage offset.

I tried doing it this way, applying the mV boost before applying the voltage offset and it still crashes as soon as I click on apply. Could this just be a case of silicon lottery?

The only thing I touched were the voltage values, nothing changed for the other settings. Nothing is active now since I don't want to crash again lol mV boost doesn't make me crash, only applying the voltage offset.

I set all of the turbo ratios to 52. Trying to run the 58 turbo ratio will likely interfere with how much you can undervolt.

That seems to be it, it didn't instantly crash now lol thanks a lot, I'll fiddle with it a bit to see how far I can push it while staying stable
