Aorus X399 / 2950X experiencing boot issues with a loop and POST code 16.
The board was released prior to the chip. It seems to lack a BIOS flashback capability; you might need to update it.
The board allows Q-Flash installation: according to the guide, insert a FAT12/16/32 USB drive with the BIOS active and press the END key during POST. Up to now, progress hasn't been made; the manual indicates the flash function is operational but video output isn't working—so it seems the device isn't reaching the keyboard initialization stage.
You're experiencing the same issue even after replacing the CPU and motherboard. The BIOS update from Gigabyte claims compatibility across all versions, but it doesn't seem to resolve your problem. It might help to double-check the BIOS version you're using or contact Gigabyte support for clarification.
Same problem again. The device has worked smoothly for three weeks. I put it to sleep last night, but it won’t start. It only cycles through codes at C0 and 16. All systems checked and reinstalled.
I realized the issue was the incorrect RAM placement. It was a simple mistake!
