Effectively, the new Zen 4 sweet spot appears to be 6000 MT/s DDR5. This runs using a 3000 MHz DRAM clock, which is 3000 MHz memory controller clock, and 2000 MHz Fabric clock. A higher DRAM frequency will default to a divider for the memory controller clock which generally imparts additional memory subsystem latency.

For the operations of each kit, we stuck with how their default on our AMD and Gigabyte test system.

The Crucial 4800 MHz kit runs at 2400 MHz memory controller clock and it defaulted to 1800 MHz Fabric clock on our test system.

The G.SKILL 5600 MHz kit runs at 2800 MHz memory controller clock and 2000 MHz Fabric.

The Kingston and KLEVV 6000 MHz kits run at 3000 MHz memory controller clock and 2000 MHz Fabric clock.
