First time builder,
I have two 8GB Ballistix Tactical Tracer RAMs for my pc. Maximus VI gene mobo and i7-4770 cpu.
One of the RAMs doesn't seem to be enabled.
Where in the UEFI bios setting should I configure it so that both RAMs work?
Also, as is the case with the drives. is it possible to see the list of connected memories anywhere?

Strange... Having swapped the two, now they both work fine... Could it be that one was loose or something can something else explain it?
