What is the best memory frequency for ROG Strix B650-A Gaming WIFI with AMD Ryzen 7 7800X3D?
For the ASUS ROG Strix B650-A Gaming WIFI motherboard and AMD Ryzen 7 7800X3D processor pairing, the optimal memory sweet spot is 6000MT/s running at latency timings of CL30. This matches standard gear settings (1:1 memory controller clocks), delivering maximum bandwidth and lowest latency.
Does this setup support CUDIMM DDR5 memory?
CUDIMMs are physically pin-compatible and will fit. On this consumer configuration, the integrated memory controller typically runs CUDIMMs in bypass mode, disabling the clock driver chip so it behaves like a standard UDIMM. Prefer a standard UDIMM 6000MT/s kit unless you have a specific reason to buy CUDIMM.
