What is the best memory frequency for B550-A Pro with AMD Ryzen 5 3600?
For the MSI B550-A Pro motherboard and AMD Ryzen 5 3600 processor pairing, the optimal memory sweet spot is 3600MT/s running at latency timings of CL16. This matches standard gear settings (1:1 memory controller clocks), delivering maximum bandwidth and lowest latency.
Should I buy a 2-stick or 4-stick kit for B550-A Pro?
Prefer a high-density 2-stick kit installed in the primary dual-channel slots. Populating all 4 slots with DDR4 often forces the memory controller to drop frequency for stability. A matched 2× kit at 3600MT/s CL16 is the best everyday choice.
