@wqco510 - Sorry, I did not know that about x.synccoreratio, thanks You'll have to ask Revlaay about the checksum thing then, sorry for being lost on that one, I assumed it did AIO (since it's AIO tool ) It probably fixes the checksum on rebuild, especially if you see it corrected in proper area post-rebuild
I'll make you fresh BIOS that's done properly, from stock BIOS, once you explain this mod they did for you at MDL. I don't see any UEFI Boot related changes, nor should any ever be needed to boot UEFI mode, unless you simply wanted some defaults changes or something (which I checked, and do not see any changed)

@wqco510 - This BIOS has ME FW 11.8, does not work with Coffee - What is your ME FW on the board now, check with HWINFO64 if you are not sure
How are you flashing in mod BIOS, and did you already downgrade the ME to 11.7 previously?
---------------------

I tested build like you mentioned with Revlaays single x.coresyncratio tool, and yes, that checksum message from x.coresyncratio is corrected on rebuild, so that BIOS should be OK too

Just so it doesn't look awkward for other readers -- Problems were resolved thanks to the hero above! ;D

@wqco510 - Thanks Yes, we just talked more in PM after here due to discussing other unrelated stuff, then carried on there

@Lost_N_BIOS - After testing with various programs and some games I noticed that the graphics card works on x8 instead of x16. Could this be a problem in the modified BIOS?

hi i want i3 9100f (SRF7W) work with Intel ME Version: v11.8, Build 3399, Hotfix 50? msi h110m pro vh - plus. Bios 7A15v1C . G4400 (SR2DC)

@Petoparac - it's been so long, what exact BIOS file that I sent you are you using so I can check it out. Did you already remove card, clean gold fingers, blow out slot, reseat card?
Does it go up to x16 if you open 3D test in GPU-z (ie hit that ? mark)

@prodan - You need flash programmer to downgrade ME FW, or do pinmod (E.1 here) so you can dump FD with FPT, unlock all regions, then flash it back, then you can downgrade ME FW with FPT
Do you have flash programmer, like CH341A or similar?

@Lost_N_BIOS - Yes, I clean the slot and pins on the graphics card but nothing has changed. It's always on x8 1.1 to 3. This is the bios you sent me

Hello, I have Asus Prime Z270-A motherboard, bios version 1203, 2017-12-25, running G4400 currently.
I just got 8600K and would like to mod the Z270-A to run it.
I'm new to win-raid and would appreciate any guidance in doing this mod, if anybody can please point me in a right direction I would definitely be more than happy to donate for their time.

@Petoparac - Thanks. I have a TON of files in folder where I did you work, did we have issues initially, or were you in bricked state and we recovered your BIOS first or something?
Can you see ME FW version properly in BIOS main page, or with HWINFO64, or do you see N/A or 0.0.0.0
BIOS Looks OK generally, for coffee mod, and in comparison to stock. Do you still have your G3900 CPU? If yes, please put it in and see if PCIE lane width instantly changes or not. If it does, then check the isolated pads and be sure none slipped and maybe covering other pins too.

@lkadlcek - What is your current ME FW version, check with HWINFO as shown below, or you may be able to see on BIOS Main page


Do you have flash programmer, like CH341A? If not, best to order one now and wait for delivery.
You need CH341A + SOIC8 test clip with cable if BIOS is soldered to board, or U Type Flat IC Extractor if BIOS is in a socket

@prodan - Sorry, I'm not watching video, and you have not provided enough info for anyone to advise you (motherboard model, CPU's and their SSPEC etc)
In general - pinmod required for any CPU except Revision B0 CPU

my sspec Intel ME Versión: v11.8, Build 3399, Hotfix 50? msi h110m pro vh - plus. Bios 7A15v19. G4400 (SR2DC) upgrade i3 9100f (srf7w) . in the video it doesn't pinmod but I'm not sure .
@Lost_N_BIOS

@prodan - B0 CPU ( i3 9100f (srf7w) does not need anything done to the pads on the CPU, but you do need flash programmer or to do pinmod to unlock FD, since your ME FW is updated too high version now (need downgrade to 11.7.0.1229)
So, you need flash programmer (CH341A + SOIC8 test clip with cable), or follow "E.1" method in this link - [Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing
Once done, DO NOT reboot until you flashed in unlocked FD, or you will have to do pinmod again.
To dump FD use V11 ME System tools package from this thread in the C.2 section - Intel Management Engine: Drivers, Firmware & System Tools

Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose "open command window here" (Not power shell! >> * See Registry file below *).

((If "open command window here" does not appear, look for the "Simple Registry Edit" below...))
Here is a [b]SIMPLE REGISTRY EDIT that adds "Open command window here as Administrator" to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <

Run this command: " FPTw.exe -desc -d fd.bin "

Then edit FD via hex editor to unlock it, per section "B" of the first link above, see section "B" Spoiler #2, image #2
Then flash it back in via >> FPTw.exe -desc -f modfd.bin

Then let me know once you are done, I will make you mod BIOS and show you how to first flash in the mod ME FW.
Otherwise, get programming tools, then once you have let me know and I will help you to dump BIOS to send to me, so I can make you a mod BIOS to program back in

@Lost_N_BIOS,
Intel ME Version: 11.7, Build 1229
I do not currently have a flash programmer.
Please see in the attached picture, is the Winbond chip in the center the bios chip? If so, than I need the CH341A + SOIC8 test clip with cable, correct?

@lkadlcek - Great, at least you do not have to downgrade ME FW, but none of that matters anyway if you get a programmer
No that is not it, the BIOS chip is to the right of the chip on the right in your image, if the chip matches what is on stock images at Asus site (ie not in a socket), then yes you need SOIC8 test clip
