On Zen 4, running UCLK and FCLK at the same frequency provides no memory latency reduction.
This is incorrect, it’s a very substantial latency step reduction and offers ideal performance in certain workloads. 8000/2000/2000 tests lower latency than 8000/2000/2200 and around 4ns lower than 8000/2000/2033.
There’s even a flag in ryzen master which shows if uclk=fclk sync mode is active or not.
