I currently own an Asus M51AC-FR034S that has an Asus M51AC motherboard. When I updated the BIOS some time ago I noticed that the BIOS file name was

H87M-PRO-ASUS-M51AC-1002.CAP

Whereas H87M-PRO's one was

H87M-PRO-ASUS-2102.CAP

After some search, I noticed that the M51AC motherboard was in fact a rebranded H87M-PRO motherboard, without the 2 eSata ports (just search on Google Images, you'll see that the two are identical).

What I want is to install the latest H87M-PRO BIOS on my motherboard to access the new overclocking features, and to solve my other question (in the changelog of H87M-PRO BIOS 0713: "2.Fix XMP button issue") Ah. My XMP button doesn't work. This could solve that. I tried to use Asus EZ Flash, it works with the M51AC BIOS but with the H87M-PRO one it shows an error "couldn't verify security key" or something like that.

Is there a way to force installing the BIOS, or to edit it to make the motherboard think it's a real M51AC BIOS?

It's possible. I do that right now. All you need is a CH341A programmer from Aliexpress and Winbond 25Q128FVIQ chip for BIOS backup "just in case". After that M51AC motherboard is regular H87M-PRO with all OC options. Works fine and stable. Sorry for dig but I tried to find a solution for this problem almost a six months and no one knows.

There is another way if you want to change the BIOS from the M51AC version to H87M-PRO version. Flash the first release BIOS for M51AC and then replace it with a BIOS for H87M-PRO, flash with the tool from AMI.

Download:

Use AFUWINGUI.EXE to do the following steps.

1. Load H87M-PRO-ASUS-M51AC-0118.CAP.

2. Check "Do Not Check ROM ID"

3. Flash

Then when that is completed do:

1. Load H87M-PRO-ASUS-2102.CAP.

2. Check "Do Not Check ROM ID"

3. Check "Program All Blocks"
Note: This will give you an error after
the tool have erased and flashed "Non Critical Block" part. But it
will clear up some leftovers from the previous BIOS. You might
accomplish the same thing by resetting the BIOS through the jumper on the mainboard.

4. Flash

5. Reboot

(I also flashed the first release BIOS for the H87M-PRO mainboard and it was possible to flash to the latest version through EZ-Flash tool in BIOS options. But that was purely for testing if it would work to do that.)

my short description:

You need another computer with Windows to do that (I done this on my laptop with Windows 10)

First you should remove the original chip from motherboard and read it in CH341 program. When you save it on hard drive, file with BIOS backup, in FD44Editor you can read motherboard SN and Lan MAC adress and other stuff, copy it to clipboard and save in notepad. Then you have to write these informations onto new fresh bios file (save it as .bin file). And last step, write the overwritten file (with .bin) to new chip in CH341 program (open the bios file and press AUTO button or ERASE, BLANK, WRITE and VERIFY). And thats all, you have full H87M-PRO motherboard :)
