Unrelated question. May I ask what software you used to UNDERVOLT? I have the same CPU and mine appears to be Locked. Thank you

I used https://github.com/DavidS95/Smokeless_UMAF to apply the undervolt at the BIOS level because I need to keep intel virtualization on (allows wsl2). If you don't you can disable core isolation and virtualization and you should be able to undervolt.
I tried SMOKELESS_UMAF and I saw the Option to Disable Undervolt. I selected it and restarted but I still could not enable an Undervolt using Throttlestop.
I have Alienware M18 with BIOS 1.13.0.
@JazzyJazzjazzy It's well-know issue - Dell block undervolt for unknown reason. Roll back BIOS.
@isaacsummers Hmm... Seems like it happened then Turbo timer expired (usually in 90 seconds). This means you PL settings from ThrottleStop not applied correctly. But 30W looks so low for me. Also, you can rename power mode into app to better understand what is it about. JFYI - digits (like 161) is a mode code into BIOS (0xa1 in your case). Performance mode usually 0xab (171), do you have it into the list? PS: I don't mess with PLs any way, i just switch BIOS modes.
When on power mode Level 161 (seems to be my high performance), ...>
When we change the POWER MODE, should the Power Mode in Windows POWER OPTIONS change to reflect current mode? For example, I am currently in BALANCED mode in Windows and MANUAL MODE in AlienFan. Now, I start changing from MANUAL Mode to the other available Options. Should the Power Mode in windows change respectively?
I ask because using "powercfg /list" shows my Power Mode unchanged when switching through the Power Mode items listed in AlienFan. Same is true for the Control Panel Power Mode.

Thanks for the response. It's actually when I don't have throttle stop open. If I do it keeps the PL static to what is set (with sync mmio). However if i don't open TS I think it's the Intel dynamic tuning platform that changes the power levels which is strange. Just wasn't expecting such a low PL for being in supposed high performance mode.
I have renamed each level but haven't checked after the fact going into the bios to see the name. With what I've observed in fan speeds and power level I have
160-balanced 161-high performance 162-quiet 163-cool 164-full speed 165-g mode
Could it be a dell bios issue. I'm currently on their latest.

It will only work if you disable virtualization and core isolation if you go that route. What I've done instead is enable overclocking in dell bios. Restart and boot into smokeless, then change the voltage offsets in there. These apply at boot and allow any range between what is set and up in TS or XTU. Note: make sure you select the offset indicator/prefix to negative
Aha! Disabled Virtualization & Core Isolation as you suggested and it Worked! Thank you!
160-balanced 161-high performance 162-quiet 163-cool 164-full speed 165-g mode
How can I correlate these values to MY power modes? Is there a CMD that I can use? Thank you.

I found the above referencing S0 Power State. S0 removes the other Power Modes; ie. HIGH PERFORMANCE, etc form the Control Panel Power Options. Only BALANCED MODE is available. It appears that we no longer have the other forms of S1, S2, S3. As a result, I will not see Power Mode changes in Windows when I select Mode 161. There is no other Power Plan visible in windows now.

First, power modes into app HAVE NO CORRELATION with the Windows Power Plan. It's just proprietary BIOS control settings provided by Dell.
The only exception is CPU MODES - which are, in fact, hidden settings into Power Plan.
Windows have a bug which can delete other power modes. There are a lot of tools around to return it back.
I thought the other Windows Power Plans needed the S1, S2, S3 sleep.statea.available?
Okay, understand I can recover the other Modes. Thank you.
You can not recover the Power Modes in Windows 11 with a 13th Gen CPU. The required Sleep States are not available nor supported by the CPU. Registry hacks do not work. S0 is the only mode available.
Standby (S3) The system firmware does not support this standby state. This standby state is disabled when S0 low power idle is supported.
This comment from my powercfg /a command says S3 is not supported. Apparently after 2020, a lot of laptops took away this option. My M18 does not support S1, 2, or 3 in Windows or the BIOS.
Commands have no effect. For example;
Even runnig below command to edit registry, nothing can be done to bring back the old Power Schemes.
reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0.

Does changing the power level in AFX change the CPU modes?

EDIT: I have found out the mV Boost is a feature of ThrottleStop, so I will have to live without it if I want to go the Smokeless route.
Do you know how to deal with "mv Boost" in SmokelessUMAF? Using "mv Boost" usually allows a TS CPU P Cache UV that causes lock ups to function without issues.
So I've looked into the original issue with the power limits. Still not sure why it throttles to 30W in 161 mode but I believe the issue originates from Intel Dynamic Tuning.
Description I'm having a strange issue where gaming on High Performance Mode with Alienware Fan Control has some strange power limits. Both my PL1 and PL2 Static are set to 200W and I have HWINFO64 to see the Dynamic power limits.
When on power mode Level 161 (seems to be my high performance), I notice that PL1 starts at 130W but after 5 or so minutes it drops down to 30W which causes a CPU bottleneck for the GPU. No issues with the Balanced Mode Level 160 as the power limit settles around 55W. The fans definitely are running faster in Level 161.
I would have thought that High Performance Mode would have a higher CPU PL1 so that it can meet higher demanding tasks especially with the fans spun up a bit higher.
To Reproduce Steps to reproduce the behavior:
Expected behavior PL1 to be higher than where Level 160 settles (55W)
System (please complete the following information):
Additional context I'm not running throttlestop or xtu and have uninstalled AWCC. I am running a -125 undervolt on p-cores and -100 cache + e-cores
