These memory modules are for server and HPC use, where memory bandwidth is still a major limitation for many workloads.
Your desktop CPU may not be memory I/O bound for your average single-task desktop use case, but a 128-core server running intense workloads or doing HPC can definitely be I/O bound.
Even desktop gaming applications show benefits from memory overclocking in most cases, so it’s not something that can be dismissed.

Indeed. From my measurements (very unscientific), processes stall first for IO, then for CPU resources, then from memory.
