I have this exact same issue except I am on a Z690 Dark board. I recently had to get a 2nd Z690 Dark board as I messed up the pins installing my 13900ks and I know Evga won't rma it with damaged pins, so I went on Amazon, and bought another Z690 Dark board on sale this time, and put it together, but when I went to turn it on it would just boot loop with error codes 04,7F,53, and 54.

I updated the bios to the latest version but still got the same thing. I tried multiple different packs of memory, of 4800, 6400, and 7200 ram, and none of them made a differance; I did notice something strange though. When I installed just one stick, of the DDR5 G.skill 16gb 6400 mhz ram in the slot closest to the cpu the motherboard after awhile would read error code 12 and then go to error code 28, and just stay there after clearing the cmos a few times, I finally got into the bios, but I noticed that for xmp it was showing as not supported for either profile 1, or 2.

I thought maybe the bios didn't update right so I updated the bios again to the same latest version 2.08, and after that I was never able to get back into the bios ever again.I even tried on all 3 bioses. Also, I noticed on my first Z690 Dark board that if I tried putting in 64gb of ddr5 6400 mhz ram from G.skill it would never work, and just endlessly boot loop with those same error codes, but then G.skill 32 gb 6400 mhz kit worked fine with xmp set, and no issues, but I had to rma the ram as one of the sticks died, and when I got the new pack I noticed the system just kept boot looping, but I found out it was because I had bent pins from installing the 13900ks as I said before.

Also, with this new 2nd Evga Z690 board I found out that taking out my Zotac 4090 and putting in my old Radeon RX 6900 XT the system boots up fine, and I can even boot it with the G.skill 64 gb 6400 mhz kit with xmp on with no problems. However, if I try putting my 4090 back in it goes right back to boot looping error codes 04,7F,5, and 54, so I know it is some issue with the 4090, and 13th gen with the z690 board. I have heard and read a lot of Z690 boards having issues with 4090s and 13th gen.

I did contact Zotac and they told me to try and turn on "csm" in the bios, and try to see if that would work with the 4090, but it did not make a differance. At this point I am not sure what to do? If I should rma my 4090 because I have no way of updating the vbios on it as I am thinking maybe it could be a vbios issue on the 4090 causing this, or just wait for Evga to release a new bios version that hopefully fixes this issue once, and for all?!

The thing is my Zotac card worked fine up until I upgraded a few weeks ago to my 13900ks on my first Z690 Dark board. Also, a little update after turning "csm" on in the bios with my Radeon card and as well as setting the memory to xmp 1. When I put my 4090 back in now error code 52 shows up for a second and then it goes right to error codes 04,7f,53, and 54.

Also, after leaving my pc off for a while like an hour with the switch turned off on the power supply; when I went back and turned my pc on, the pc actually booted into the bios, but after that it failed trying to boot into windows. I notice if I let it sit for awhile like a half hour or more it will actually try, and boot into the bios before giving up, and showing the same error codes 04,7f,53, and 54.

I am thinking it has to be something either with the 4090 like it needing a vbios update or the motherboard needs a new bios update from Evga to fix this issue?!

Yes I did try and reset the bios to default settings, and it seems it makes it worse. If I leave the bios with "csm" on and xmp on the bios will try, and boot normally with the 4090 before it gives up, and goes back to the error codes.

Just In: It was announced that Intel 600 and 700-series motherboards will now fully support 24GB and 48GB DDR5 memory modules. As a result, Intel's latest 12th Gen and 13th Generation Core processors can now support up to 192GB of DDR5 memory based on Intel's latest chipsets. Will the Z790 KP follow suit? Or are we married to 2x32GBs max forever?
