The HPE P00924-B21 is a 32GB dual-rank x4 DDR4-2933 Registered ECC SmartMemory module built for 2nd Generation Intel Xeon Scalable (Cascade Lake) processors on HPE ProLiant Gen10 servers. Operating at 2933 MT/s with CAS latency 21 at 1.2V, this dual-rank DIMM represents one of the most widely deployed memory kits in enterprise VMware ESXi and Hyper-V clusters. Pre-owned buyers must verify genuine HPE SPD authentication to maintain error logging and fault isolation in iLO 5.

About the P00924-B21
The HPE P00924-B21 was introduced alongside the 2nd Generation Intel Xeon Scalable refresh (Cascade Lake) for HPE ProLiant Gen10 servers, upgrading standard memory transfer rates to 2933 MT/s. With a dual-rank 2Rx4 architecture and 32GB density, it became the benchmark DIMM for virtual host sizing, enterprise databases, and container platforms. It delivers an 11% memory bandwidth increase over earlier 2666 MT/s modules while maintaining broad availability in secondary markets.
Compatibility
Compatible with HPE ProLiant Gen10 servers including DL380, DL360, DL560, DL580, and ML350 Gen10. To achieve native 2933 MT/s operating speeds, the host server must be populated with 2nd Gen Intel Xeon Scalable processors (Xeon Silver 4200, Gold 5200/6200, and Platinum 8200 series). When paired with 1st Gen Xeon Scalable CPUs (8100/6100/5100/4100 series), the memory automatically down-clocks to 2666 MT/s. It is incompatible with Gen9 (DDR4-2133/2400) or Gen11 (DDR5) platforms.
How to identify a genuine unit
Authentic P00924-B21 modules display an HPE SmartMemory label with Option Part Number P00924-B21, Spare Part Number P03052-091, and module code 32GB 2Rx4 PC4-2933Y-R. In HPE iLO 5, genuine modules display full telemetry with serial numbers matching physical stickers and valid HPE signature validation. The bare DRAM ICs originate from tier-1 manufacturers including Samsung (M393A4K40CB2-CVF), SK Hynix (HMA84GR7CJR4N-WM), or Micron.
Buying used
When evaluating used P00924-B21 modules, carefully inspect the 288-pin gold edge connector for missing or damaged pads. Verify that the registered clock driver (RCD) chip situated in the center of the module is undamaged and free of heat burn marks. Run memory testing via HPE Intelligent Provisioning or UEFI diagnostic utilities to verify zero single-bit correctable or multi-bit uncorrectable memory events in the iLO Integrated Management Log.

FAQ
Can P00924-B21 mix with 32GB DDR4-2666 (815100-B21) modules?
Yes, they can physically co-exist, but the server memory subsystem will down-clock all installed memory to 2666 MT/s. For optimal throughput, match all DIMMs to DDR4-2933.
What is the difference between P00924-B21 and P00922-B21?
P00924-B21 is a 32GB dual-rank (2Rx4) module, whereas P00922-B21 is a 16GB dual-rank (2Rx8) DDR4-2933 module.
