Hey guys,

Recently bought a gigabyte X570 Aorus Ultra. I installed it with all components and started it up and it wouldn't post. I had a quick look around and realised the DRAM light was on on the board and around every 20 seconds or so it would switch to the CPU light for a second and then back to the DRAM light. I unplugged the system and reseated the CPU, AIO, and ram to no avail. I then tried seating the ram in different positions and managed to get the system to post with one stick in A2. I had a look on the Gigabyte website and saw there was an update that fixed ram compatibility (F22) so I downloaded it and updated the bios. After doing so I reinstalled the ram and booted the computer again only to get stuck in a post loop. After removing the 2nd ram stick I've started up logged into windows, checked and updated drivers and came straight here to ask you guys.

PC will boot with either ram stick but not both and all components work fine in the previous motherboard.

Any help would be greatly appreciated
