Problem with RAM recognition in BIOS setup.
You might be dealing with a motherboard problem affecting the RAM. The BIOS doesn’t recognize any memory, which could mean faulty modules or a hardware fault. Check the connections and try reseating the RAM sticks. If the issue persists, consider testing with a different motherboard or consulting ASRock support for the B450M Pro4 model.
Use one stick at a time. Update the BIOS. Remaining specifications?
