When I built my pc I bought 16gb (2x8) of ram. For the Christmas season I decided to gift myself 32gb (2x16). Both sets are ddr4 and run at 3200mt/s but are of different brands. Is it okay to put them in the other two ram slots or should I replace the old ones?
at worst, they are incompatible and the pc only recognizes one pair of sticks. in that case, remove the 8gb-pair. As always, follow the instructions for the mainboard on how to populate the ram-slots.
