@pepeo - No need to apologize, at least for you, but there is for me!! Sorry about this, I will get it sorted out one way or another!
The issue is I rarely do this swap, maybe only a few times, I'm usually swapping in an entire menu or submenu, instead of a single setting (from the hidden debug area at that too)
So things are a little bit different for that and I need to remember which specific things need swapped for setting move and which do not.
As I mentioned, if I don't get it for you shortly, I will do on my end and then I will be able to quickly figure out via a bunch of test edits without hassling you to do that
The hard thing about sorting this one out is with simple setting swap vs a menu, I can't see it fail in AMIBCP when using that to double check (it all looks correct, even ones I checked initially that I did not send your way)

Here, I think one of these is the answer
Clear CMOS after each flash, load optimized, save/apply/reboot, then check.
You only need to do that once, and no need for cold boot test, it should be there instantly once edit is 100% correct.

Please test both, even if 2a works, test 2b, and let me know outcome, thanks!

Thanks, youre the best. I will test later today, after i get back from work.

You're welcome, and thank you!
If neither of the above get it, then I'll get out my Z87MX-D3H and get to the bottom of this for you on my end, then there wont be any issues after that

Ok so i got back and tested both but still no luck. I did like you said, clared cmos, then load optimizated settings, save/apply reboot, and still cant see it.

@pepeo - Sorry Hmm, lets test the basic thing (correct access level or not) here before I dig out my board (I think I have to recover it's BIOS first too)
Can you see RealTime CPU multi in BIOS with this - https://ufile.io/mjpdqvgk

If you can't see it, then this may be simple mistake I was doing (+access level Super) that's causing all edits after this to fail, and I may need to use Access Level User instead (or default/ie no change to access level)
If you can see it, then the issue is with the actual setting swap edit and not this basic thing of making that setting visible in that position. I'll have to get my board out, unless you do not care, and don't mind continuing more tests?
Sorry I've already had you test so many BIOS, usually this is an easy thing for me, although it takes forever to do it's usually not an issue (but, as mentioned, I usually swap in entire menu)

* Edit - Yippee! I found my notes on a similar "settings" only swap around - for this board/mod - [Request] Gigabyte OEM Z370-HD3P - Option "HPET" missing in updated bios
So go ahead and test above so we're sure that is OK, and then I am 99% sure once I have a second to redo this edit it will be proper

Thanks, ill test when i get home, give me 2 hours and ill report back
-------------------------

@Lost_N_BIOS so i got back and tested, and i cant see the option, so i guess its the acess lever user thing you said. If you need any more testing just le me know.
Thanks again

@pepeo - Thanks, good to know info!
While that is not the main issue, that would cause an issue with the swap once done, because it needs to be made visible too. So, we need to test these two BIOS now, to be sure which way makes it visible, so that once the edit/swap is applied, the setting will be visible.
One of these has to work, since the previous one did not, this is simple setting reveal edit, and normally for a test like this, I'd send you previous + these two and you'd let me know which worked then I'd unlock the rest of the menu.
This should be a no fail edit, I do these all day long every day, for all brands. Unless there is something odd going on here, like I should use AMIBCP to set access Level instead of doing it manually, or something else random, it can't fail

* Edit - Noticed another possible thing that will cause an issue here!
Due to the setting I was choosing being a "Checkbox" type vs "One Of", I think it's better we pick another option to swap, and none are ideal in the sections I had you send me images from.
Please send me image of >> MIT >> Miscellaneous Settings, thanks

Here, I think 3DMark01 Boost (if you don't use this), or Isochronous Support (if you can't see it, then perfect ) one of these are much better choices to replace with HPET.

Oh sure, ill get home in 3h, then ill post the screens and test the newer files. If you want to edits while im out, you can replace 3dmark boost option since i dont use it. Thanks a lot
----------------------

@Lost_N_BIOS so i tested both and i still cant see anything, ive looked everywhere in the bios to make sure i wasnt missing it. Did the clear cmos and reboot thing also everytime.

@pepeo - Thanks for the testing info, maybe this BIOS needs AMIBCP to do the access level change then, instead of me manually doing it, some BIOS are weird that way
Anyway, yes, best to do on another setting anyway, I made a bad choice picking that one due to it's type and didn't realize until today.
Please send me image of >> MIT >> Miscellaneous Settings
I'll leave 3D in case you want it later, if you cannot see >> Isochronous Support << then we can just replace this instead

@ Lost_N_BIOS You're welcome, sory by the delay, i forgot about the print, i had taken it earlier but forgot to upload.
And yes, i cannot see isochronous support (is that a useful feature anyways? dont even know what is it lol)

here goes the screen, thats the only miscellaneous page i could find

@pepeo - No worries, I'm never in a hurry, always buried anyway, and trying to work on 10 things always, so I'm a mess and behind no matter what
I had to look it up myself, and found these two threads that explain it a bit
https://www.overclock.net/threads/what-i...s-z68x.1481303/
https://forums.tomshardware.com/threads/isochronous.204697/

Default is enabled, and it will be left that way when I replace it, so nothing will change in regard to this and how you've been using system currently.
So, first thing, make it visible!! Sounds trivial to me, since I make entire hidden menus visible for users all day long, but seems that's an issue on this board for some reason

Pre-post edit - Never mind!! Isochronous is a "Checkbox" type setting too, not ideal for what you want to swap in, so I guess we are stuck with 3DMark boost.
Unless you want me to find and select another possible hidden ideal setting instead? There is some in Peripherals we could probably use?

Or, I see on BIOS Features page, you have this disabled, we could swap there too if you wanted >> Intel TXT(LT) Support

@Lost_N_BIOS You can replace the 3dmark option for sure, but if Intel txt is easier, you can also do it

@pepeo - Either one is OK, I double checked to be sure this time
Here, replaced 3Dmark setting - https://ufile.io/iyen9bju

AND....... This one is PROPER now
I double checked post edit to confirm all is correct by testing changing the HPET fail safe/optimal setting one by one, then extracting the NVRAM and AMITSE/SetupData where the setting is changed when you change it in BIOS, and each time, correct offset/variable is changed as expected
So, all should be good to go right away this time!!! Sorry for the initial hassles and all the testing here!

@Lost_N_BIOS You're the best, ill give it a go in some minutes, cant thank you enough

@Lost_N_BIOS so i tested it now and unfortunately i still cant see the option, i still see the 3dmark option, and on CPU advanced settings nothing changed as well. I am questioning right now if there is anything wrong on my end, im flashing it with qbios (f8 on bios) then shut it down, turn it on and clear cmos, then aply recomended settings and reboot, shut it down and reboot again.
I took a screenshot of my system information so you can have a look and see if at least the bios was updated as it should (not sure if thats enough info, if its not, just let me know what info you need)
In any case, i supose that the NVME boot is possible with this bios? if so at least that already enough so i will save this file for when my SSD arrives
Thanks again
