@xlegacygt - No, there is several SB Clock Spread Spectrum settings in there, one is hidden and only one is the one you want. This is not what I meant about upper/lower BIOS images, and two setups and or other modules.
Search this GUID and you will find both Setup modules, one at top image (upper) and one at bottom image (lower) >> 899407D7-99FE-43D8-9A21-79EC328CAC21
Both of those, you generate IFR from, and that is what you'll be editing. The SB Spread Spectrum that is the one you want to edit / make visible is the one that has D.O.C.P setting directly above it (ie (VarOffset/VarName): 0x48).

Sorry, I can't comment on using UBU for any of this, it's not used here nor should be. Use UEFITool to extract what you want to make IFR's from.
UBU's extraction is for another purpose, and I don't use so I can't tell you what the files you asked about are, only that you should not use this for BIOS editing, less confusion if you do the extract yourself directly.
Always extract and replace same way, if you extract As-Is, replace As-Is, if you extract BODY, replace BODY

Yes, BIOS editing can be tricky, especially if easy to use GUI based tools do not work and you have to use other methods.
All edits I will do here involve use or UEFITool 51.0 for extracting the modules, and UEFITool 25.0 for insertion back once edited, but all can be done with 25.0 if you wanted
Then any hex editor (I use hex editor NEO)

This is what is suppressing SB Clock Spread Spectrum (if User or Super), and they doubled it up for no reason trying to make sure (as if one wasn't going to work)
This is from "Setup PE32" module GUID - 899407D7-99FE-43D8-9A21-79EC328CAC21 - Extracted as-is, then IFR generated to see readable info using Universal IFR extractor then you can use this info to hex edit

CBS items are suppressed similarly, but in a different way to suppress, one example below

Here, please test in the following order, and let me know which BIOS shows you "SB Clock spread spectrum" Stop flashing once you see it, no need to test further
Also, you should now see the setting above in CBS, please confirm too, then if yes, I will do rest in CBS, unless you want to?
1. SetO
2. SetAMITSDU
3. SetAMITSDS

https://ufile.io/n6qemavx

Also, I checked, and for Access Level Changes, AMIBCP only edits one image (The upper area, so if that does not apply to your CPU then AMIBCP changes would not work for you if needed, and you'd have to do edits manually to the lower area instead)
Manual changes to Access Level without using AMIBCP are done in AMITSE >> B1DA0ADF-4F77-4070-A88E-BFFE1C60529A >> AMITSE/Setupdata >> This is actual target you edit >> SubGUID >> FE612B72-203C-47B1-8560-A66D946EB371
Then, changes are made how I give in this example, see last par of the post at bottom of #4, and check the image to see about Access Level - [Request]Maximus XI Hero - Unlock AMIBCP
For this BIOS, you make the edit on two AMITSE/Setupdata modules, to cover all bases for all CPU's (Same for all edits done here, since you are not sure which area applies to your CPU type)

@Lost_N_BIOS beautiful, thank you for all the information. Of course its a lot to process but I will compare your edits with stock edits and learn of it.

The first bios you posted did not unlock Spread Spectrum but the 2nd one did. "SetAMITSDU"

As far as the CBS menu I see you messed with "PCIe ARI Support" but this option was already unlocked with the screen shots I provided you.

Couple questions.

-Did you end up modding the upper image? If so, this would mean I can use AMIBCP 5.02.0031 to set "user" or "supervisor?"

-When using UEFITool to look through the bios, how do you determine what PE32/module image you need to extract to make proper edits too? There is a lot of PE32 images.

-Also, how do you determine what part of the hex is actually causing the suppression? How do you look at "0x426E6 64 Bit Unsigned Int: 0x1 {45 8A FF 00 00 00 00 00 00 00} << Target/Nulled" and 0xB70D QuestionId: 0xF equals value 0x1 {12 86 0F 00 FF 00} << Target/Nulled and determine that hex is causing it?

If you dont mind unlocking the rest of the CBS I would be beyond grateful, I do want to do my own edits but I need proper tools in case I brick my board.

@xlegacygt - Ahh yes! Sorry about that, on CBS, I thought it was missing, didn't see it below but I see it now!
This may mean the CBS I mentioned and edited isn't the one your BIOS is using too, there is three. I will have to check them all more closely, if you want me to to the CBS mods too.

I modified both upper and lower, this is what I always do unless user is already sure which applies to their BIOS, otherwise you'd have to do some test with edit to only one then the other, to figure out which applies to your CPU.
So, still not clear here which applies to your CPU, direct upper only and lower only test would be required. If you want me to make you two BIOS so you can test that I will.

SetO = Setup only edits
SetAMISDU = Setup + Access Level Edit to AMITSE/SetupData (both upper/lower), so AMIBCP may or may not work for you, after you do the setup edit.
You can test, use SetO and do AMIBCP edit SB Clock Spread Spectrum to User, if it does not show then your edits only need done to the lower area of the BIOS and would need manual edit only for Access Level Changes to be applied
If it shows, then you only need to edit the upper area of the BIOS, and can use AMIBCP for Access Level changes or default changes etc

In UEFITool you expand Setup or AMITSE for what we're discussing, and there you extract it's PE32 (for AMITSE you are not editing it's PE32 right now though, but the subGUID below it (AMITSE/SetupData)
I gave the GUID's for all above, search via GUID with UEFITool and it will show you at the bottom, upper and lower, click each to go directly to the location.

You tell what is suppressed by the IFR output, you can tell what is the part to edit by what I bolded below, sorry I didn't make that as clear above
0x426E6 64 Bit Unsigned Int: 0x1 {45 8A 01 00 00 00 00 00 00 00} << Target/cause of suppression
0xB71F QuestionId: 0xF equals value 0x3 {12 06 0F 00 03 00} << Target/cause of suppression

I just know from experience which is what, but you can see by how it's coded usually, suppress is = 0x0xx, and then the code string you find that 0x0xx and FF it

Yes, tonight when I have time, I will unlock the rest of CBS (properly this time )
I will include the before/after CBS file too so you can see what was edited and how.

@Lost_N_BIOS you're awesome thank you.

Question, what is AMITSE exactly? I noticed you mentioned setup and AMITSE.

Is AMITSE just for access level of "user", "supervisor?"
----------------------------------

@Lost_N_BIOS I know I may be overthinking a lot of things but do you mind checking out my image of my hex edit to ensure I'm doing it correctly?

Steps taken:
1- Used UEFITool to search for "899407D7-99FE-43D8-9A21-79EC328CAC21" I was also able to find it by just searching Spread Spectrum within UEFITool and they both provided "899407D7-99FE-43D8-9A21-79EC328CAC21."

2- I took the "top" PE32 image section and only extracted that file "as is" within "899407D7-99FE-43D8-9A21-79EC328CAC21."

3- I used Universal IFR Extractor on the PE32 image section.

4- I searched Spread Spectrum and found the section with "Suppress If."

5- I made the hex edits which I provided images for here. https://ufile.io/gvy71cyz

@xlegacygt - You're welcome, and thank you! [cool
AMITSE (AMI Text Setup Environment) This is what we often edit to do major menu changes, such as add/remove main sections.
The AMITSE/SetupData (subGUID in this case) is where the settings fail-safe/optimal and Access Level values are stored (along with other data and layout info)
You do not edit AMITSE for the stuff you were asking about here, only AMITSE/SetupData, per the link I gave you above at end of post #16 - Follow link, read bottom of that post and see the image, for how to do Access Level edit manually

To use your Top Only Setup edit as tester, to see if your CPU uses upper section of the BIOS, you will also have to do the AMIBCP edit on top of that.
Then if this does not show, your CPU used bottom area of the BIOS instead, then both edits there would need done manually @ Setup PE32 and @ AMITSE/SetupData
Yes, your hex edit image shows a correct edit You can double check your work after you save it, by generating a post-edit IFR with new mod file name, then look at the same are and be sure your edits are as intended
The edit's are correct, but just letting you know this is easy way to check.

* Edit - ON CBS, after further checking your image vs the three possible CBS files, this is your BIOS CBS and it's in the lower section only, so that may be the area of the BIOS user per your CPU
8E38A88A-C267-4131-A8CD-C0BC80A24CB5

If you want to edit yourself, you need to know this >> 47 02 (TRUE) >> Edit to 46 02 (False)
I see right towards the top, several submenus suppressed via 47 02, then some other stuff suppressed in ways we've already discussed.
But, if you get stuck, or still just want me to do it, let me know

Thanks for all the assistance I feel so much more comfortable now.

Fingers crossed my CPU is based on the top image of the bios lol.

@xlegacygt - You're welcome! Don't worry, if it's not, you know how to do the edits manually now
I think it's the lower one, based on the CBS being used

If the manual AMITSE/SetupDate edits have you concerned, don't worry too much, it's only that one setting really, at least that you've mentioned (the SB Clock Spread Spectrum).
And if you just need that edit done, and or others, and feel like you can't do that kind of edit, let me know and I will do for you
Or, you can simply extract the lower AMITSE/SetupData module from SetAMITSDU above and swap into your working edit, and or compare that with a stock extract and you will see the one byte changed to 2D instead of 09
This Access Level change by itself will not be shown in AMIBCP, it will still show as "Default"

@Lost_N_BIOS well good news! My flash was successful and I'm not bricked, thats a +1 lol.

Bad news is, you're right. Its the 2nd image so I can't depend on AMIBCP. I will mess around with this next.

Lets say I do brick, does the motherboard have some sort of recovery? If not, how I fix it?

Yes, +1 always great when flash reboots without a brick!

No, there is no auto-recovery, be careful!! There is no recovery from brick except by you manually, and this is not possible, unless and until you have flash programmer in you hands >> CH341A + SOIC8 / SOP8 test clip with cable.
The tools are cheap, but if you order cheap ($7-8) it takes 3-5 weeks to arrive, you can pay more and get them quicker, this usually makes price around $12-15 depending on where you are and where you can shop etc.

Unless you insert something wrong, like body >> As-Is or As-Is >> body, generally if the menu edits are wrong and it's not a bad insertion, then you just may not be able to enter BIOS, but it wont brick, and you can then reflash from DOS
But, that may not apply to all bad edits, so just be careful, double check, look things over as much as you can

If you want me to do, I can, just let me know! Or, if you want, upload your mod BIOS files and I will check, before you flash, to be sure all looks OK.
If you do this, please include all files you edited, and the final mod BIOS, I will only check the files you edited + the BIOS itself, so if you edited something else be sure to include it

* Edit - What is inside "AMD Overclocking" is that AMD PBS?

@Lost_N_BIOS I did it man!!!!

Beyond excited, I feel so accomplished lol.

Seriously, I couldn't have done it without your guidance. It seriously means a lot.

I will try CBS at a later time.

Gonna send you a PM.

@xlegacygt - Awesome to hear it man, congrats!! That's really pretty in-depth edit too, for someone not familiar with BINOS editing and hex editing etc, great job!
So, you did the AMITSE/SetupData edit too, without even having to ask me for more details other than I provided in the linked post on other thread? If yes, super great, nice work

CBS, you can look through the IFR from that GUID, and see if anything is missing that you'd even want, may not be anything that interests you? I didn't check again yet, was waiting to see if you wanted me to do, or if you'd hit it yourself.
Did you see my edit above, about "AMD Overclocking"? I'm wondering if that's PBS in this BIOS, I think it is. Show me an image of inside if you are not sure. Lots of goodies in there
If you want to generate PBS IFR's and see which one applies to what's being used in your BIOS, to maybe unsupress stuff in there too, here is it's GUID (There is upper/Lower) BBB77CB9-762D-436C-AC40-8EE4901C3446
Never mind upper/lower, I guess we now know it's all about Lower for your current CPU

Also, setup can be edited in same way to unlock suppressed submenus or settings that you didn't ask about or mention here, in Advanced (usually some submenus hidden), or Ai tweaker for example (usually some settings hidden)

@Lost_N_BIOS I did the AMITSE/SetupData edit as well, I followed the link you sent me lol. At first I was confused because I couldn't get a IFR for AMITSE/SetupData and then after reading the link you sent me it went smooth!

I will def look around at some of the things you mentioned.

AMD Overclocking has a lot of the same options that AI Tweaker has, its actually pretty strange because AI Tweaker and AMD Overclock both have PBO options, ram overclocking, etc. It seems like AI Tweaker takes priority over some things. I dont know why they have the same options in 2 menu.

------------------------

@Lost_N_BIOS hm so taking a look at the CBS menu I found items I want to unlock but changing the suppression from True to False (47 02) does not unhide the menus for this one. Any ideas?

I changed 3 suppressions from True to False.

https://pastebin.com/BjhrGqBa

Edit: These items dont have a questionID unlike the other ones.
Edit again: Is it possible this CBS menu is using the top image instead of the bottom?

@xlegacygt - Nice to hear you figure it out! Yes, no IFR from AMITSE or AMITSE/SetupData, those are more code/layout than settings like Setup or CBS etc.

Sorry, I don't know AMD very much. What is PBO? Did you look at the IFR from the PBS mention I mentioned? Is that what is inside AMD Overclocking?

It's possible that the CBS menu that I first edited was the correct one, and not the one I mentioned later? Maybe the options appear in BIOS different order than the appear in IFR output, sometimes this is the case.
If so, you'll have to try and edit each CBS menu, until you figure out which one is actually being used by your BIOS currently, this may be unrelated to upper/lower or CPU type etc.
Here is all three CBS GUID's, generate IFR from each, and then do same edit to each one at a time, until it works on one and then you know that's the one being used.
Or pick some other suppressed singular setting to edit that you don't see in the BIOS (unsupressing, or moving outside suppression as shown below), until you figure out which actual GUID is being used, then you can do the more major edit like you mentioned
3E7788CA-2BFC-4FCE-8122-5176CA492D9F
8E38A88A-C267-4131-A8CD-C0BC80A24CB5
A5E369C8-ABF9-4B43-B212-FF1BFD35666D

If doing True >> False does not work on either of the three CBS menus, doing the same three edits to true that you linked, then it may be for this edit CBS situation that you need to move the items outside of the suppression.
This involves cut / paste (Insert, not paste over), and when doing this you must be very careful to not add/remove any bytes, ending result should be exact same bytes total that the original file had.
This kind of editing can be VERY tricky!! So be careful, and always double check output file IFR to see that it all looks as you intended, after you double check output byte sizes matches original.
If you want me to do this kind of edit for you let me know

@Lost_N_BIOS I got CBS unlocked! It turns out the "3rd" image I tried was the right one "8E38A88A-C267-4131-A8CD-C0BC80A24CB5." All I had to do is change suppression to false, I didnt have to move any data.

I'm still wondering how you locate these files easily. My UBU doesnt tell me what each module is, if that makes sense.

I normally go to search and type in "CBS" under text with unicode on and it gives me 2 results, I would've never found the 3rd result if it wasn't for you telling me.

Sorry, I don\'t know AMD very much. What is PBO? Did you look at the IFR from the PBS mention I mentioned? Is that what is inside AMD Overclocking?

@xlegacygt - That's the one I said was your CBS at post #20
I locate the CBS/PBS by known settings inside and or known hex codes for their names >>
59 B9 63 B8 C6 0E 33 40 99 C1 8F D8 9F 04 02 22 - AMD PBS
E3 35 45 B0 04 30 46 49 9E B7 14 94 28 98 30 53 - AMD CBS

Thanks for info on PBO Often, PBS is a submenu like CBS, if none of that matches what you see in "AMD OC" section, then we may need to do different edit to make PBS appear in there, I've not looked at this for you to see if it's where it should be to be visible or not (I will check now)
I checked, and it's not there, but sorry I am not 100% sure how to add it into this BIOS to make it appear. So hopefully anything in there you may want is in other menu. If not, let me know what settings you need to change, and to what, and I will show you how to do and or give you edited files to replace (This involves in-depth NVRAM edit)
