Frequently Asked Questions

What is the difference between DDR4-2933 and DDR4-3200 for 32GB RDIMM?

DDR4-3200 provides approximately 9% higher theoretical bandwidth than DDR4-2933 — 25,600 MB/s vs. 23,467 MB/s per channel. DDR4-2933 is the maximum native speed for Intel Xeon Scalable 2nd Gen (Cascade Lake) on HPE Gen10, while DDR4-3200 requires 3rd Gen Ice Lake on Gen10 Plus or later. For Gen10 Cascade Lake servers, DDR4-2933 is the optimal and certified speed.

How many P00924-B21 modules can an HPE DL380 Gen10 support?

The HPE DL380 Gen10 supports up to 32 DIMM slots (16 per processor socket) with dual Intel Xeon Scalable 2nd Gen (Cascade Lake) processors. With 32 x 32GB DDR4-2933 RDIMMs, the DL380 Gen10 achieves 1TB of DDR4 memory — sufficient for large virtualization, database, and enterprise application workloads in a 2-socket Gen10 configuration.

Will P00924-B21 DDR4-2933 work in a Gen10 Plus or Gen11 server?

DDR4-2933 RDIMMs are backward compatible and will function in Gen10 Plus (Ice Lake) servers, typically operating at DDR4-2933 unless the platform supports higher speeds for the installed module count. DDR4 is not compatible with Gen11 DDR5 servers. For Gen10 Plus servers, DDR4-3200 modules provide better performance when the platform supports it natively.

The HPE P00924-B21 delivers 32GB DDR4-2933 ECC RDIMM capacity in a 2Rx4 configuration — providing the standard per-slot 32GB DDR4 memory for HPE ProLiant Gen10 Cascade Lake servers, offering certified DDR4-2933 performance for virtualization, databases, and enterprise workloads with full ECC protection and HPE Gen10 platform compatibility.
