DDR5 Memory Kit (2x16GB)
The D3 code indicates a failure during the DXE phase where architectural protocols cannot be loaded into the system memory. This is most frequently caused by a hardware-level instability in the DDR5 modules or the failure of the memory training sequence, which prevents the CPU from establishing a stable data bus. Replacing the modules with a kit matched to the motherboard's Qualified Vendor List (QVL) ensures the memory controller can successfully initialize.

CR2032 Lithium 3V Battery
A depleted CMOS battery causes the system to lose its volatile BIOS settings and saved memory training parameters. On the X670E platform, this often forces a full retraining cycle on every boot; if the battery cannot maintain the minimal voltage required to hold these parameters, the system can hang at code D3 as it fails to recall the previously stable architectural protocol map.

MSI MPG X670E Carbon WiFi Motherboard
If replacing the memory and battery fails, the failure likely resides in the physical trace layers of the PCB or the BIOS ROM chip itself. A defect in the SPI Flash ROM or the traces connecting the CPU socket to the DIMM slots will prevent the Driver Execution Environment from successfully loading the required firmware protocols, necessitating a full board replacement.
