Bank address hashing only starts to matter when you're operating at the edge with high-frequency DDR5, tight tertiary timings, and an integrated memory controller that's already being pushed close to its limits. In these scenarios, inefficiencies in how memory requests are distributed get magnified a lot more than usual, and weaknesses in linear mapping are exposed. That's where hashing can step in as a subtle but meaningful refinement. I wouldn't recommend looking into bank address hashing unless you already have your memory pushed to its limits, and you're familiar with memory tuning and the
