  1. Best answer
    You want DDR5, it is much faster than DDR3, the standard for RAM in PC's has been DDR3 for a while, in the near future they will switch to DDR4, so consider the switch from 3 to 5 a 2 generation jump, much faster.
  2. you can pair any one ddr3 or ddr5.i suggest pair with ddr5 as it is much faster than ddr3
  3. Same thing here, you should definitely get DDR5, it offers twice more bandwidth for the memory compared to DDR3.
  4. Thanks guys :)
