What it is

P00926-B21 is an HPE Smart Memory RDIMM for ProLiant servers that use DDR4.
It’s a 32GB DDR4 Registered ECC module running at 2933 MT/s with CAS 21 timings, qualified by HPE for Gen10/Gen10+ platforms. Think “the standard HPE 32GB DDR4-2933 RDIMM you add when you want reliable, supported server RAM.”

Why buyers pick P00926-B21 (plain English)

• Certified ProLiant compatibility
  HPE Smart Memory is validated for Gen10/Gen10+, so you avoid the “will it boot / will it downclock” surprises.

• 32GB is the practical scaling step
  Big enough to materially increase VM/app density without the price jump of 64GB sticks.

• Server-grade reliability
  RDIMM + ECC protects uptime and data integrity in 24×7 workloads.

• Health + performance visibility
  Smart Memory enables clean DIMM telemetry and tuning in HPE firmware.

Where it fits (and when to choose something else)

Perfect for:

• Expanding memory in Gen10/Gen10+ ProLiants

• Virtualization hosts, databases, general enterprise compute

• Filling channels properly for best CPU/memory performance

Choose something else if:

• Your server is Gen11 (DDR5) → use DDR5 Smart Memory instead

• You need more capacity per slot → 64GB / 128GB DDR4 RDIMMs

• Your platform requires LRDIMMs → use DDR4 LRDIMM kits
