After reading some posts here, I have reformat the usb into MBR and Fat32. And, I have changed the version to 2.10 instead of 2.13 due to some posts claiming that 2.13 may have problem to support RTX 4090. When I use the EVGAE699.bin name, I still got the E1 error, then clear the CMOS then power off. After this, I changed the file name to EVGAE690.bin, and proceed with the same update process, this time, I see the POST LED showing countdown in numbers with decimal, then stop at 1.5. 
 
I have changed back the filename to EVGAE699.bin, the same 1.5 code remain.
 
What should I do now ?

So.... Safe assumption this board isn't going to get the Intel microcode update to stop the 13900k degradation issues huh. My first EVGA board and what a disaster this has been.....

I've been running the z690 dark kingpin with a 13900k @ motherboard defaults for 1.7 years. My cpu is still working. I've been using bios 2.03 the entire time. Don't trip.

I used the 5.5 ghz overclock present built into the board for 12+ months. Fast forward to this January/February and my PC would BOSD constantly. Ended up having to underclock the CPU to 5.2 ghz all core for it to be stable. Intel RMAed my CPU due to the degradation.... So I would like to prolong the replacement.

Try the process with 2.03, see if it will work and then you should be able to boot into BIOS. Once there, install 2.13 from within BIOS. I have some vague memory of this being an issue for a couple people.

All we can do right now seems to be undervolt (negative vCore offset, increase vDroop, etc.) and set a CPU power limit. Also might be worth opening a ticket with EVGA and asking directly. It's been a very long time since any employee has participated in this forum, so contacting support might be the best way to show interest in a potential update.

HI @B0baganoosh,  thank you for your reply. I have followed your suggestion to use version 2.03 but still stuck at the 1.5 on the POST LED. This is the url "drive.google.com/file/d/1hc_lksBwlRBjBMewoV_C2MZFXHLH6RnE/view?usp=sharing" to my recording. The flashing at the end is actually the 1.5 but may be it is too fast hence you can see flashing.
 
I have asked EVGA Tech support but have yet receive reply from them on this 1.5 issue.

As I recall, BIOS version 2.05 solved the E1 error for me. I remember when I first got the Z690 KP and I had 2 bad flashes that bricked BIOS chip 2 and 3. I was able to bring them back to life with BIOS version 2.05 and all 3 BIOS chips have been working fine since then.

Hi @RavenMaster, Currently what I am facing is not E1 but 1.5 on POST LED. For my knowledge purpose, may I know how you actually bring back the bricked BIOS chip with 2.05 ? Update bios to each of the bios chip 1,2,3 ? or just update bios 2.05 to one of them and the other 2 can automagically unbricked ?

Well, you put the USB stick with the BIOS update into the motherboard socket, boot into a BIOS that is working (in my case BIOS 1 was still functional). Once into the BIOS screen flip the BIOS switch on the motherboard to BIOS chip 2, then navigate to the flashing option in the menu and flash the BIOS. This unbrocked BIOS chip 2. I repeated the process to revive BIOS chip 3 also.
 
If you're having trouble getting the motherboard to recognise a RTX 4090 or 4080 card, flash ur GPU BIOS with this Nvidia's update: https://nvidia.custhelp.com/app/answers/detail/a_id/5411/?=&linkId=100000163736896

Hi, I follow the listed instruction and start the bios update, I think the process is failed. Basically after press the BIOS update button at the back of the IO panel, the POST LED start count down to C, then I release the button, the POST LED shows 13? or E1 (not sure how to attach image here) ? What should I do now ? Keep the mobo power on ? or Can power off and try again ? 
 
 

What USB drive do you have? Not all flash drives can be flashed. The file system must be fat32. I can flash from the entire zoo of flash drives that I have, which is more than 10, from an old flash drive that has a volume of 4 GB. Nothing comes out of all the others. Dig in her direction.
 

try to flash the first BIOS version available for your motherboard. and then flash the version you want.
I've corrupted BIOS on my 790 DKP a few times and was able to successfully recover by first flashing v1.03 and then the latest. I hope this helps.
I also use a 4GB USB 2.0 drive
