Pro Disk Network Buyer’s Guide: Server Memory

Compatibility: Rank, Density, and Channel Population Rules

Quad-rank modules behave differently from dual-rank: most modern Xeon platforms support 1-2 DPC (DIMMs per channel) at full speed with single- and dual-rank modules but downclock with quad-rank above 1 DPC. RDIMM and LRDIMM are not interchangeable in the same channel. ECC and non-ECC cannot be mixed. Server motherboards expect server DIMMs — the 408853-B27 is a server module and will not work in consumer desktop boards.

Pricing Strategy: New, Bulk, or Refurbished

If you are buying 16 or more modules at once, request a matched-lot quote: sequential manufacturing dates and serial numbers, which reduces variance in observed memory speeds across the channel. Pro Disk Network ships matched-lot orders for free on volumes of 16+.
