DDR5 Desktop Memory Kit
Code 55 specifically triggers when the motherboard cannot detect or initialize the RAM modules. This is often caused by a faulty SPD (Serial Presence Detect) chip on the module or a hardware defect in the DDR5 ICs that prevents the memory from responding to the BIOS handshake during boot.

LGA1700 Contact Frame
The Z790 chipset uses the LGA1700 socket, which is known for a factory loading mechanism (ILM) that can bend the CPU substrate. This warping causes pins associated with the memory controller to lose contact with the CPU pads, resulting in a persistent Code 55 even with functional RAM.

If RAM modules are verified good and the CPU socket pins are not visibly bent, internal trace damage within the PCB's multi-layer memory routing or a failing BIOS ROM chip necessitates a full board replacement to restore the memory communication path.
