It involves some complex details. Certain chips support 6400 in single-channel mode, though not many exist. Most handle 6200 in the same setting. By default, anything above 6200 uses a 2:1 scaling, but recent updates have improved this behavior. The 1.0.0.7b AGESA released today on ASRock boards addresses this issue, enabling proper 2:1 scaling and allowing higher memory speeds on Intel boards at lower voltages. It also permits chips to operate at faster rates in single-channel mode, which should make 6400 work on more devices with reduced power consumption.
AMD 1:1 matches Intel's Gear 1 version. Gear 2 corresponds to a 2:1 ratio.
Nope, FCLK isn’t fully independent in Ryzen 7000. Whether you’re using DDR5 6000, 6400 or 8000, the default is 2000MHz. Previously, UCLK limited it to a 1:1 setting, but now board signal quality can affect it in 2:1 mode. There used to be a requirement for a 1:1:1 ratio in Ryzen 3000/5000 for optimal performance; that’s no longer necessary with Ryzen 7000 where you can choose any frequency combination (like 2133MHz FCLK and DDR5 5800). Still, UCLK and MEMCLK must maintain a 1:1 or 2:1 relationship as they did in earlier generations. Talk about Gear mode on Intel – AMD’s version keeps memory controller and memory clocked together for lower latency, but switching to 2:1 can boost speed if the memory is fast enough. Initially, Intel said 6000 CL30 was ideal, but it’s unclear if that was due to untested benchmarks or whether the real issue lies in latency penalties that might outweigh gains at very high clocks.
