@Petoparac - If testing Coffee CPU, did you isolate/connect the pads on the CPU properly? The stock mod BIOS I made you at 1062 should work no matter what, especially with older CPU, does it not work even with old CPU? If not, then your writes with programmer may be the failing issue here.
To confirm if this is the issue, do a write/verify, then close the program, open it again and read/verify, save and then compare that file with the one you wrote in hex editor it should be 100% match, if not then we found the problem.

Maybe DOA CPU?? Was it used? If yes, I'd go ahead and test the other one just to be sure it's not the CPU, or test that CPU in another board that is compatible if you can.

As for VBOOT_TEST, I am not sure, it's right beside LN2, so may be voltage related, or may be verified boot test.
You'll have to ask about that one at Asus forums, google was no help except a few reviews mention it without describing

@Lost_N_BIOS - All attempts were with the old CPU and I prepared and tried the new one only once. I did everything and checked as you described and there were no differences after writing and comparing. It's not even clear to me why it won't work when I "clone" the chip? Two completely identical chips with the same BIOS, one works and the other does not (passes reading, writing and verification).
At the moment I don't have any other board and no other CPU that fits my motherboard to try.
My old CPU is G3900 (I tested everything with him)
and new is i3 9100f (Isolated and connected pins)



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

@Lost_N_BIOS - I tried to modify the BIOS again and this time everything went smoothly. I used CoffeeTime_0.85a software. The bios I modified is identical to the one I sent you. I used the advanced option, inject all CFL microcodes with keep existed and I added MAC address. I don't know how to add addresses for both LAN ports.
I'm sending you files so if you can see if everything is ok.
Download BIOS link
For now, the conclusion is that I have a problem with the chip that I use for the test, so I will order a new one and try it again.

Edit - What is the difference between Consumer and corporate ME ver. and what should I choose?

I apologize for the two consecutive posts.

I found a new bug, my cache ratio always stays at 4.3 ghz. Can I change it anway? Want to go to 4.6 ghz, that's what worked for me on skylake

Does anyone have a ported bios from Asus Maximus X Formula for Maximus IX Formula with support for i9-9900K/KF P0 and R0?

@Petoparac - If all test done with the old CPU, then OK, good to know, one of those last two I sent you should work with the old CPU for sure. What do you mean one BIOS works and one does not? If you have one faulty BIOS chip, which it sounds like, then don't use that chip anymore.
Manually verify via close app, open, read/verify/save and then hex compare with what you wrote, is best way to confirm write is OK when you are not 100% sure

For the ME, you choose #1. I used coffee time Advanced too, and step #4 will make BIOS in "Possible" brick state adding padding files to the main DXE volume, this needs done manually. Same for microcodes. So I do step #4 manually first, then all steps with coffee time, then microcodes manually last + Fix FIT once done.
So, I don't need to check file, I know it's in possible "May brick BIOS" state due to both of the things mentioned above. You can test, sometimes those things do not need to be worked around and can be OK on some boards, sometimes... Only test will let you know.
I work around always because maybe = brick not acceptable for me to hand BIOS to users that way, unless they know in advance and have programmer/ready to recover and know we are testing out if that is OK on their system or not.

@davidtheking - Can you now see/change that in your BIOS? If not, link me to the BIOS you are using and I will make it visible for you

Hi folks
There is so much information here, I don't know where to start. I have an ASUS ROG Strix Z270f motherboard (updated to latest BIOS 1301, unfortunately) and I'd like to use a Core i3 8100 or 9100 (whichever is more stable for daily usage) on this motherboard. The most difficult thing I have done in tech world is installing CyanogenMod on an old android phone.
So, What would you recommend me to do?
I appreciate it.

Edit: My motherboard ME Firmware version is 11.8.50.

Hi, will this tool work with bga1440 modded lga1151 like ql3x(7820HK es) , ql2x ?

@kazp3r - Isolate pins as mentioned in all guides, once you get programmer let me know and I will make proper BIOS for you so there will be no mod BIOS concerns
When it arrives and you post back, be sure to tell me your old CPU model, and your new CPU model AND SSPEC off top of CPU

---

@Lost_N_BIOS - Yes, all tests were done only with the old CPU. The chip goes through write and verification but will not start the computer. It starts and works normally only with the chip I read and sent that BIOS to you. It does not work with the other chip, although it passes the verification before and after the test on the board.
I will try to get a new chip and then try everything again and report the results.

Does the file size matches expectations to the bit? If, for whatever reason, the read out is only partial, than writing will also be only partial but it will exactly match the read out.

@Petoparac - write the BIOS to the other chip and see if it then works, if so then you know that one chip is faulty somehow.

@kazp3r - What is your BIOS chip ID? Then I will tell you what software to use to dump chip and send to me so I can edit for you.

@Lost_N_BIOS - Today I ordered a new chip from France so when it arrives I continue with the tests. I'll let you know what's going on with the new chip.
Thank you so much for all your help

@Lost_N_BIOS - I was able to fond this on top of the BIOS Chip

254128A
13EDF
99CHN
639118

Here is a picture of the bios chip, but I believe is not very clear
I have a backup that I made with AFUWIN, not sure if that helps, if not I can still send you the dump fille, just let me know what software shall I use

Thanks again for everything I really appreciate all the effort

@kazp3r - On that board should be a 25Q128 (Micron) chip.

@kazp3r - That does not look like BIOS chip ID, but to be sure, clean it off with alc and show me new image.
No, AFU dump is not used here, we want programmer dump but it needs to be done properly so we know it can be written back properly.
I cannot find anything in google with the ID you mentioned, so must be some letter/number incorrect.
If it's Micron >> 25Q128A as Petoparac mentioned, this is 1.8V chip, so you need 1.8V adapter and to use software "CH341A v1.31(1.4) (CH341AFree)" from this package - http://s000.tinyupload.com/index.php?fil...213094641136166

@Petoparac - They put whatever BIOS chip is in the wave solder setup machine at the time, some have Winbond in reviews I checked just now.
But, looking at his image, I think you are correct, I see the E4 logo

On your board, why wait, you said you have a known working chip you can erase/write etc, put that in and test, you can always put back current contents once done.
