Pro Disk Network Buyer’s Guide: Memory Boards
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 501-7818 is available across three procurement tiers, and the choice is driven by criticality, warranty coverage, and budget. New (sealed OEM) units carry the full Sun manufacturer warranty and command a 20-30% premium over bulk-OEM tier. New (bulk-OEM) units are factory-fresh modules sold without retail box. Refurbished units come from decommissioned servers, are individually MemTest-validated, and carry a 90-day advance-replacement warranty.
