Those are the exact directions I followed. It is not that the offsets are not saved, but that they cannot even be written. The setup_var command fails to even write the new values.

I ended up figuring it out. Virtualization-based security was "Enabled" on my system even though it should have been off. It was disabled in the bios, in the registry, and also all of the features were removed from Windows Apps and Features. I had to use the group Policy Editor to get it to truly disable though. Once I did that IETU started running without an issue. That also allowed me to confirm that this CPU has definitely completely locked out the ability to undervolt. I saw some other folks online had managed to unlock it for this exact CPU via editing their BIOS, but for the P16 that also appears to be locked down completely. I was able to dump the BIOS, search for the exact data in the BIOS, and found that the Overclock Lock was located at CpuSetup 0x10E and defaulted to Enable. I then turned off secure boot in the BIOS and booted into Grubefi without issue and tried to edit the overclock lock to disabled, but even though UEFI tool indicates that this lock is not protected by boot guard at all, I was unable to write to the BIOS. It appears to be locked down and write protected, thus my final dead end. So it looks like I can monitor data now with the tools but Undervolting is currently completely disabled. It is also greyed out in ThrottleStop.

Checking with HWiNFO64 based on that thread it is disabled for me, with nothing in the BIOS to enable it. The problem is that Intel Extreme Tuning Utility wont even run anymore unless you enable it. But if you enable it that defeats the entire purpose of running IETU to undervolt my laptop. So I have a few problems here. 1. I cannot enable Undervolt Protection on the P16, which would allow IETU to run. 2. If I COULD enable Undervolt Protection and allow the app to run, I would not be able to undervolt due to turning on the protection. So I need to know how to run a version of Extreme Tuning Utility that actually allows me to undervolt, and I want to know why Japiyapi was able to run a version of the app that wont actually run without Undervolt Protection turned on. How did he get the app to either ignore the check, or how did he enable Undervolt Protection on the P16?

I do have the latest Bios installed but it has never worked for me for the months I have had the Laptop and I actually updated it specifically to try to get it working. That is why I was trying to figure out how he got it working. Hopefully he will reply and clarify if it is because of the BIOS version.

How exactly did you get the Intel Extreme Tuning Utility to actually run on a P16 Laptop? I have tried every version from 7.6.0.37 up to the latest 7.10 build. Including the 7.9.1.3 version you are running. The older versions will not launch at all, and the newer versions now have a built in check to make sure that Undervolt Protection is enabled in the bios, and as far as I can tell that option is not even available on my P16 to enable or disable. So when attempting to run the Intel Extreme Tuning Utility now it just throws an error saying it is Unable to start. Feedback about my laptop specifically, with the hardware I have I have extreme heat problems, and power issues, which cause severe performance drops. As long as I am using it normally it is fine, but if I actually use software like Blender, DAZ, or gaming the power brick cannot always keep up with the use of the laptop. The Laptop will throw error messages that it is not being supplied enough power sometimes, and even plugged in it uses more power than can actually be supplied. I tried two different 230Watt power bricks I have, as that is what comes with it. On top of that, the power bricks occasionally actually get so hot that they will completely shut down and stop working sometimes up to 20 minutes, while they cool back down to a usable, not burn you when you touch it, temperature. When the laptop is fully loaded as well it cannot keep all of the USB ports and HDMI port working properly. So if you for example plug in an external monitor or VR headset like an Oculus CV1 into the HDMI, and devices into the USB ports they will keep dropping connections, the USB more often than the HDMI, but both common enough to be considered not truly usable. My specs specifically are maxed out. In the laptop is the RTX A5500, i9-12950HX, 128GB DDR5, 2 2TB NVMe Drivers, and the 4K OLED Touch Screen. Just sitting here typing this message in a 60 degree room, while copying some files, with absolutely nothing else running or going on, the Core Max temperature of the CPU is jumping all over the place, going between 52 to 70 and back, and triggering Thermal Throttling on and off repeatedly. Here is the error message, and here is CINEBENCH R15 results requested above as well.
