NEW BUILD - ASUS ROG STRIX X870E-E - 4d ERROR CODE

[works_arc]

Hi, I'm having trouble with my new build, and I'm getting a '4d' error code. I've reseated the CPU and updated the BIOS through the non-posting method. Below are my specs. Do you have any advice? I am going to try a CMOS reset in the interim.


Asus Rog Stix X870e-E
Asus Tuf Gaming GeForce RTX 4090 OGOC
Samsung Pro SSD 1TB
Cosair Vengeance 64 GB DDR5
AMD Ryzen 9 7950X3D
Noctura NH u12a
EVGA Supernova 1600P+

First boot? AM5 systems can take a few minutes to train memory and configure hardware before anything appears on screen.

More or less the first boot, the mobo was displaying a green VGA light and the BIOS update resolved that issue, However, the red light/4d code now illuminates after the BIOS update. I'll fire it back up and let the RAM warm up like its an old diesel Mercedes.
Thanks for the note!

OK - Its been running a while and still the b4 persists. Any recommendations are welcome.

Well, now the error code is 4d. Maybe I was crossed-eyed yesterday!

Remove the 4090 and use the integrated GPU (yep, you have one). Any difference?
