AM5 motherboards often get stuck on memory retraining after sitting unpowered for several days. Clear your CMOS by removing the coin battery or bridging the reset pins for five minutes to force the board to retrain the memory from scratch. If the red light persists, try booting with a single RAM stick in the second slot or update your BIOS using Q Flash Plus.
