Pro Disk Network Buyer’s Guide: Memory

Compatibility: Rank, Density, and Channel Population Rules

Memory population order for Xeon Scalable is documented in the motherboard manual; the typical rule is to populate channels symmetrically across both CPU sockets and across all six channels per socket. For two-socket builds with eight DIMMs, populate the white slot first on each channel; for sixteen-DIMM builds, populate both slots on every channel. Asymmetric population leaves performance on the table.

Pricing Strategy: New, Bulk, or Refurbished

The A9773A is available across three procurement tiers, and the choice is driven by criticality, warranty coverage, and budget. New (sealed OEM) units carry the full HP manufacturer warranty and command a 20-30% premium over bulk-OEM tier. New (bulk-OEM) units are factory-fresh modules sold without retail box; Pro Disk Network warranties them for 36 months. Refurbished units come from decommissioned servers, are individually MemTest-validated, and carry a 12-month advance-replacement warranty.
