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?
As long as OP has something newer than a 1st gen zen CPU and MOBO 3200 should be easily doable on all 4 sticks, but it probably won’t be officially supported.
