I assume you're using 4 modules of memory, so the while the capacity is high, the bandwidth is low.

Low being relative.

6000 C28 at 256GB using 4x64 is not at all on the bandwidth high end these days, but it's way more than DDR4 could provide.

Most boards support 4x64 at 5600+ now, some go to 6400 with it if you tune voltages and terminations. .
