Better two dual-rank dimmers than four single-rank ones.

Consider adding more RAM for the FX8320. Either four single-rank DIMMs or two dual-rank ones in dual channel works, but the frequency matters. It should be OC to 1600 MHz. Your current setup struggles with stutters in most games, likely due to RAM limitations. For better performance, go with 16 GB if possible. The key is matching the frequency—1800 or 2400 MHz—and ensuring the RAM supports it.
It's worth noting that the count of DIMM slots isn't related to whether dual-channel is enabled. The channel count reflects the memory controller's capabilities and its parallel usage, not the number of slots you possess. You can still operate in dual-channel mode even with four RAM sticks.
I didn't own that CPU line before, but on newer systems, usually the total rank per channel matters more than individual module ranks. It's not about how many ranks each part has, but overall rank across channels. For example, one dual-rank module per channel works the same as two single-rank modules if everything else matches. Theoretically there might be a difference since rank and 2DPC timing can vary, but in practice it seems consistent.
