DDR5 RDIMM
Host memory for GPU nodes; increasingly the cheap tier next to HBM.
Why this part
The cheap tier next to HBM rather than the fast one, and its role in a modern accelerated node is capacity rather than bandwidth: HBM handles the arithmetic-adjacent working set, and DDR5 host memory holds everything that does not need to sit next to the compute die. Grace's LPDDR5X and Turin's twelve-channel DDR5 are both answers to how much of a node's total memory should be this ordinary, ungrudging, expandable tier rather than the expensive stacked kind.
