Thanks Lost for your help!

EDIT: Maybe can be a good idea to use a SOIC8 clip test adapter to flash bios without pulling it off?

That will cost you more, but if you feel safer that way you can do that, but you need larger test clip than usual SOIC8 those are designed for 200mm soldered on BIOS and do not line up with pins on DIP8. You need one that would be wide enough to fit DIP8 chip (300mm)

You could purchase a chip puller if you are uncomfortable wiggling it out. Something like one of these - https://www.ebay.com/itm/253510259610

here's my backup bios readed by ch341a.

The fd44edtor can't open this file and i don't know why...

FD44 is for Asus only. Did this file verify before you saved? If yes, it looks OK to me too, you can go ahead and erase, blank check, open BIOS file from post #8, then write and verify.
Or you can use this BIOS, I took same one from post #8 again with fixed/update ME, but this time unlocked the FD for you now since you are using programmer, that way it will remain unlocked unless you overwrite with other stock BIOS using programmer later.

Wait, sorry for the above, don't use! I'll need to edit in your board specifics before you program anything! Or re-edit your dump with the other changes, so sorry, please wait before doing anything

*Edit, here is updated file based on your dump. This has fixed/update ME, unclocked FD, and ME reflash enabled in BIOS from previous mod (Irrelevant now since you will re-write ME with programmer at same time as writing BIOS).
Please program this with programmer. Before starting board please remove CMOS from board and remove power plug from wall, press and hold power on button or short power on pins for 10 seconds or so, then leave board like that with zero power for 1+ minute.
You can do this before or during or after your programming procedure, just be sure power is removed fully for 1+ Minute to reset ME state. Then put BIOS back into board and start up, enter BIOS and load optimized and set SATA to what you need, then boot to windows and check it all out.

go ahead and erase, blank check, open BIOS file, then write and verify (I set auto to write verify only, and do last two steps as auto, first two steps unchecked in auto and do manually)

ah ok thanks...this is for my old specifics? how i can write it?

Please see above edits, refresh page I was editing in reply while you posted your reply

yes i read it. Thank you so much!
I've just verified that bios and it's ok! Now i ask you: how can i read old specs from this bios to write them in new clear bios?

WE DID IT!



GREAT JOB!

now i can overclock easy! all options are unlocked! You are the best!



how you wrote my old-bios information to new bios?

Great all is well and your overclocking already again! I need 4Ghz quad again!

I didn't have to copy anything, since you gave me programmer dump. All I did was redo my mods from the stock BIOS to your dump instead (ME and microcodes + FD unlock and ME Reflash enable).
Your board details were already in the dump, so all I had to do was reapply all those mods again on the dump instead of the stock BIOS.

If I were to have to do it manually, serial, LAN MAC ID etc, you can find in certain locations of the BIOS sometimes, otherwise usually in SMI section or stored in NVRAM all visible in the dumps

Understood!

Thank you again!

Now my stable overclock is 4.4ghz with +70mv voltage. I hope this topic will help a few people...

Very nice OC now, even better! And you're welcome again too, glad we could figure it out!

sorry to resurrecting this old thread, I do have the same issue! ordering the ch341a programmer and should be arriving tomorrow. So in order to continue you need my backup bios right? or maybe you can show me a guide how to insert the my unique board ID etc to the new bios file.

Btw, I'm using one version older bios than Ray's as I am using pcie to nvme adapter and the newest bios (version 3.00) somehow does not recognize it. I had to use bios version 2.90P https://www.asrock.com/mb/Intel/Z77%20Extreme4/#BIOS

I had similar issue as Ray, iGPU does not work, cannot overclock, and the 2nd 16x PCIE slot also not working (I was using this slot for my pcie 4x to nvme drive, had to move it to pcie 1x slot to make it work) I hope this will fixed all the problems :D

ok, got the original bios read and saved, please see the attached link

So what should I do next?

Hello to everyone,
One question, what kind of CHIP ID did you have selected for flash and backup?
Thanks a lot
