Ok guys, I've been talking with my contacts and can confirm that the Fatal1ty Gaming K4 is EOL but the reason for it is nothing to do with memory. The reason for the board becoming EOL is purely down to components the board was made with becoming increasingly difficult to obtain due to supply shortages so Asrock just decided it would be better to respec the board and release it with a different name to keep things simpler. Rest assured though that the Gaming K4 will keep getting UEFI updates and support.

Hopefully this will clear up any confusion and rumors regarding the K4
