Frequently Asked Questions about P38477-B21
Is the P38477-B21 a genuine HPE part?
Yes. Pro Disk Network sources every P38477-B21 as factory-original HPE inventory verified against the manufacturer parts registry before listing. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned HPE servers, surface-tested, and re-warranted by Pro Disk Network for 12 months.

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 P38477-B21 is available across three procurement tiers, and the choice is driven by criticality, warranty coverage, and budget. New (sealed OEM) units carry the full HPE 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.
