Hey there, I see you're facing an issue with your new build. You're using a Gigabyte B550 Gaming X V2 board, 5800x CPU, Aorus Master 3080, and an 850W PSU. You have two RAM pairs: one with T-Force Delta 2x8 at 3200MHz and another with Corsair Vengeance 2x8 at 3200MHz. The problem is that when you enable XMP or Resizable profiles or use both together, the system starts into BIOS and shows "No boot drives detected." It seems your drives aren't showing up in the boot section, which is confusing. Someone can help clarify what's going on.

TL;DR, start with this guide then enable Resizable BAR. Disable CSM first—your drive can’t boot under UEFI because it needs GPT-partitioned drives. Running multiple DIMMs isn’t safe, especially with XMP enabled. XMP doesn’t affect CSM or boot devices. It seems the UEFI might be saving incorrect settings.

Wow, it functions properly now with both Re-Bar and XMP. I believe XMP always worked before; it seems turning on Re-bar caused the boot drives to vanish and not reappear on the next start. It’s working correctly now, thanks a lot!
