i have tested it but the io shield has never been opened so I dont believe the board has actually been used. most likely an opened customer return.

images show the board tested with 2 and 4 DIMMs. The BOOT debug light is on because no SSD/HDD is connected and this is expected behaviour.

listing is for board, box and io shield.

Ram, cpu and gfx card are for illustration to show the board working only.
