The Q-code 53 on the intal motherboard means that the memory is abnormal.
It is recommended that you first try to refer to the "Troubleshooting for Memory abnormal" section in the link below to confirm the memory problem.
The ROG MAXIMUS Z790 HERO QVL list, on the other hand, includes several of G.SKILL, 6800, 2x 32GB, or 2x 16GB quantities.
None of the requirements are the same as what you provided, which is four modules in a single kit, and it is unclear which one you actually have installed.
Therefore, it is recommended that you insert one or two memory modules (which come from the same kit) into the designated slot
and confirm again after you have set the default BIOS.
