   Hi Cameron.

I'm since about 3 weeks been experiencing the same issue as described by others (owned this system since january).

It is in fact not hanging at the memory training, as it goes past the blinking DRAM light, but gets stuck once it's at the green BOOT status light.

	Hi all! I found the culprit for me! I made a post about it on Reddit for those interested. For me it was a bug where values of Competitive/Aggressive DRAM Profiles weren't properly reverted when switching back to AMD AGESA Default profile: https://www.reddit.com/r/ASRock/comments/1o47ent/fix_for_asrock_stuck_green_boot_light_issue_after/
