Question No signal after successfully updating Z690 bios with 12th gen chip to version supporting 13th gen and then installing i7-13700k ?

[LarsLarsen5]

Hi everyone, after having done some research it seems that this issue is a widespread problem. Therefore finding a solution is not only important for me, but for all the people trying to resolve this issue via. forums.

I updated the bios on my Asus Prime Z690-P Wifi with a 12th gen chip to a version supporting 13th gen, and successfully booted into windows.

When inserting the 13th gen i7-13700k, i get "no signal" output even though all fans are spinning + lights etc.

When switching back to 12th gen cpu, it doesn't POST either.

Update 1: Got the i3 to boot windows again after building outside of case and clearing cmos, i then proceeded to install MEI drivers in windows.
Update 2: Still no signal after inserting i7-13700k with installed / updated MEI drivers
Update 3: Successfully updated bios to 2212 and booted into windows with i3 12th gen. Still nothing with i7-13700k. i7-13700k does heat up, so i don't think its dead.

Things i've tried:
Clearing CMOS
Swapping M.2 slots
Running 1 ram stick
Reseating CPU

I know that there are some clever minds on this forum, so let's try to find a common fix for this common issue.

Thanks in advance.

Which bios version did you install?

Which bios version did you install?

1620 - the one supporting 13th gen. I've got the i3 to boot windows again. The bios version 1620 is running fine. I'll try to install Intel ME which has been recommended another place.

Make your mind - both above can't be true at same time. It either still works now with 12th gen or not?

At first the 12th gen did not post after switching back from 13th gen. I got it to boot now windows after building outside case. That's why i wrote it as an update.

Ok, so that was just a temporary problem with 12th gen. That means nothing got broken meanwhile. In that case you should try to update BIOS even further, I would say to at least version 2014 (don't forget all the necessary IME updates). If that won't help then probably your new CPU is faulty.

I'll try updating bios and report back.

Reset CMOS before swapping CPU. If that does nothing then my call is bad 13700.

Is i7-13700k really bad even though it heats up?

It is rather rare for a CPU to be bad, but yes it can happen even if it heats up.

Have you tried both cpu power pins plugged in?
