@stefanr740 - Yes, PDR/GbE does not exist is normal, I will check it out the images. * I checked your images, BootGuard is not enabled, thanks for checking. And not being able to dump ME is normal too

Thanks for jumping in to offer help too @Falkentyne - which method do you use to unlock OC tab in this BIOS?
I did three methods in the files I sent him, but will have to check my folder for this to know which I tried. * Edit - I checked, I did IFR enable, AMIBCP Enable, and IFR+AMIBCP - all mainly root OC tab unlock only, except with all I also enabled first 1-2 settings (only) within as initial check test.
So asking to see if I've already used the correct one since he said all failed. I only enabled root of the OC folder, and a quick test, three ways, maybe one I did was correct but needed to further set/enable the rest inside for him before it would be visible.

I simply set the OC menu to supervisor in the parent menu.
This works in the Gt73VR bios to unlock even menus that won't appear in the 4 key unlocked combination (e.g. menus which are not designed to be used with that hardware, like AMT configuration, Platform settings, etc).
The GT72VR was not designed to have an OC menu as far as I know, as these SKU's were originally made for HQ series CPUs (6700HQ and 7700HQ). The 6820HK model is a very rare SKU, and I have never seen anyone get power limit overrides to work on it. I actually believe now this is caused by the Embedded controller, not the bios, if the EC doesn't have a "power ID" for an unlocked CPU.
I saw someone's EC dump and this SKU had a "20" value stored in EC RAM register E3 (viewable in RW Everything -->Embedded controller).
I actually changed the value in my EC on the GT73VR (default value is 90 for GTX 1070 in kaby lake GT73VR), from 90 to 20.
The bios seemed to recognize the change and allowed a power limit override of custom TDP (e.g. 200W) for only 28 seconds. Then power limit 1 flag came on. No PL2 flag ever came on. For example changing the EC register E3 to 30, for example, causes PL2 to get flagged instantly as soon as you exceed 45W.

This is unavoidable if there is no other unlocked SKU present in the EC itself.
@stefanr740 can try changing the value in EC RAM register E3 to a value of "10", however if this value is not recognized for a 6820HK SKU, he will have instant 45W TDP throttle right away, and is better off changing it back to 20.

Imon slope = 10 should make the CPU report its using less power than 45W and should avoid problems. But again i do NOT have this laptop. I cannot test these things.
Imon slope =10 works wonders on the 8750H and 8850H and 7700HQ MSI laptops.

Thanks, would User work there too, or only Supervisor (07)? Thanks for all the additional info too, hopefully it will help him some!

@Lost_N_BIOS @Falkentyne

I think i have found the menu strings in the hx editor. (picture included)

the string: 01 01 00 00 01 01 01 00 00 00 (00), only found 1 identical result

can i maybe change the string to : 01 01 01 01 01 01 01 01 01 01 (01).

These are the related posts on other forums.

Should i change the string, ore is it to dangerous.

This is one of the things we all look at first usually, so I've checked about that method long ago. I find 28 results of the string you provided on straight BIOS search and zero in setup module
The one you are looking at @005717a0 is some settings enable/disable values inside a padding file that contains some NVRAM variables outside of NVRAM section in a RAW file at GUID 77D3DC50-D42B-4916-AC80-8F469035D150, scroll up a bit and you'll see the NVRAM header info (Again this is outside NVRAM area too for anyone reading later)
You can check that in UEFITool Action, go to offset and then you'll see the GUID where it's located, if using UEFITool NE you can hex view and see same hex you have open. These string values always only inside setup module, some rare instances AMITSE, but it's never any that seem like it in NVRAM which is all zeros and ones

That value you are using >> 01 01 00 01 01 01 01 00 00 00 doesn't apply to your BIOS, if magic string method did work for your BIOS, then you would need to get your own string value based on what you see in actual BIOS vs what you see for root menus in AMIBCP, not what any guide gives as a standard example
"IF" just looking at your setup section vs AMIBCP, you would get the following for a magic string to try and find in your BIOS >> 01 01 00 00 00 00 00 01 01 01

Normally, when setup contents are it's own submenu this method does not apply like you are seeing in those guides. I've explained it a few ways here too, see the images at both links, for how a normal BIOS this works in looks in AMIBCP
[Request] How to Access Locked/Hidden BIOS Menu Settings (16)
Also here, shorter - [Request] How to Access Locked/Hidden BIOS Menu Settings (12)

When this works easily, the BIOS layout is like your BIOS setup submenu, only setup is not a submenu it's the main menu and all the rest are submenu's under setup. Hard to explain I suppose but see images above too for another example
This is the standard look of a BIOS layout in AMIBCP when that method does apply

And the string is usually trailed by ee 2e 20 71 53 5f d9 40 ab 3d 9e 0c 26 d9 66 57 (This is in your setup, but magic string is not)

@Falkentyne Wich number in the EC must i change (picture included)
I think i have the right number, but i am not sure. it's the 20 marked in light gray. E0 03

@Falkentyne, so i tried the different numbers. nothing works, i will not risk bricking my laptop with the other EC firmware, but thanks for the suggestion tho. (latest firmware was installed)

@Lost_N_BIOS So i tried to find that string, and i found 4 results. but all in an Nvar entry ore something. so as you sad there is no magical string in the bios setup. i tried to find some toturials for modifying the AMITSE module, but i think this will not help me.
So is there any other method to modify the bios, ore is my bios unhackeble. I'm still searching for new toturials, but they all are from 2014 ore older. some newer,but just explained differently.

Any other methods?

imon slope doesn't work at all. tried imon slope 1, 10, 20, 50, 80, 90 also imon offset set to 1, 10 20 50 100 150 and 255. but nothing changes.

@Falkentyne said AMIBCP alone enables root menu's access (like OC menu), so once you enable that you can enable any setting within using AMIBCP >> User, and if any of those fail you can edit IFR/Hex to unsuppress.
I stopped on this, assuming you had BIOS from Falkentyne that was all unlocked now, correct?

@Lost_N_BIOS hi, the bios from Falkentyne didn't unlock the OC section ore something else. But with a key combination that only works on msi motherboards, i get more menu's, but not the ones i need.
thats why i am still searching for other torurials.

The last thing i tried was modifing your bios (biosreg-BCPIFR.bin) from your quick test. i set more to user in AMIBCP and modified the IFR in bios setup module to unsuppress. but that didn't work. still the same bios entries as the pictures i provided for you. also supervisor doesn't work either.

(the bios of Falkentyne unlocked nothing.)

sorry that you misunderstood it,

Stefan

Sorry I'm unable to help (besides the unlock code).
Even though I have the unlock code. I get lazy to always use it, so I manually unlocked all my menus months ago, which works correctly, except some "Submenus" which are only supposed to appear if a primary option is set to "enabled", which enables submenus that are 'supposed to be hidden' if the option is disabled...but anyway i enabled everything manually.

I have no idea why it didnt work for you :(

@stefanr740 - Sorry, I thought he had it unlocked, and I tried all the ways except his way alone. You guys both have MSI motherboards, so same/same
Anything I sent you is only meant as a test, not for continued use nor for further editing, if the root menu didn't unlock in any of those files no other changes will help either (Mainly, don't waste your time with that, as mentioned it's only for a quick check for you to let me know results as asked back then)

@Falkentyne - you have this board and BIOS, with unlocked OC section? And if yes, only via AMIBCP edit? If yes, thanks, I will try that alone, had not tested that yet since stefanr740 said he already did but maybe he did incorrectly or with wrong version etc
