Question Asus ROG Strix x870e-e Q-code "4d", no post

[zzzSean]

Losing my mind here. 4d is mentioned nowhere in the manual, and i've been without a PC for about a month now due to my 9800x3d breaking during the holidays, and the warranty warehouse bein out of stock. Bought a new 7800x3d to hold myself over while AMD refreshes its stock.

Specs:
AMD 7800x3d
RTX 4090
64G DDR5 Trident G-Skill
1350W Thermaltake 80+ Gold

Steps to cause this to happen:

1. I received the board, installed everything, then flashed bios to the latest version
2. Power on the machine, it had a 'bios updating, please wait' screen, and then reboot itself
3. After RAM training, it will always emit a red CPU light followed by error code 4d.

Steps I've taken to troubleshoot:

1. Reset CMOS and flash bios back to default version. No result, error code still 4d.
2. Reseat CPU and swapped power supply. No result, error code still 4d.
3. Swapped ram sticks. No result. Error code still 4d.
4. Removed GPU and connected an hdmi cable to on board graphics. No result, error code still 4d.
