HP 64GB 3200MHz DDR4 PC4-25600 ECC Registered CL22 288-Pin DIMM 1.2V Dual Rank x4 Memory Module – P68071-001

HPE P68071-001 64GB DDR4-3200 ECC RDIMM — 2Rx4 Server Memory

The HPE P68071-001 is a 64GB DDR4-3200 ECC Registered DIMM providing dual-rank x4 server memory for HPE ProLiant Gen10 Plus servers — delivering CL22 latency at 3200MHz (PC4-25600) with 1.2V operation. Functionally equivalent to P68070-001, the P68071-001 represents an alternate HPE part number for the same 64GB DDR4-3200 2Rx4 RDIMM for Gen10 Plus Ice Lake server memory configurations.

Frequently Asked Questions

What is the difference between P68071-001 and P68070-001?

Both are 64GB DDR4-3200 ECC 2Rx4 CL22 RDIMMs at 1.2V for HPE ProLiant Gen10 Plus — they are functionally equivalent alternate HPE part numbers for the same memory module. Both are interchangeable in supported HPE Gen10 Plus servers.

What advantage does DDR4-3200 provide over DDR4-2933 at 64GB RDIMM?

DDR4-3200 provides approximately 9% higher theoretical bandwidth than DDR4-2933 — 25,600 MB/s vs. 23,467 MB/s per channel. This improvement benefits memory-bandwidth-sensitive workloads such as HPC, large matrix computations, AI inference, and streaming analytics. DDR4-3200 requires HPE Gen10 Plus (Ice Lake) for native support; Gen10 Cascade Lake servers top out at DDR4-2933.

How many 64GB DDR4-3200 RDIMMs can an HPE DL380 Gen10 Plus support?

The HPE DL380 Gen10 Plus supports up to 32 DIMM slots (16 per socket) with dual Intel Xeon Scalable 3rd Gen (Ice Lake) processors. With 32 x 64GB DDR4-3200 RDIMMs, the DL380 Gen10 Plus achieves 2TB of DDR4 memory — sufficient for large virtualization, HPC, and in-memory database workloads at DDR4-3200 bandwidth.

The HPE P68071-001 delivers 64GB DDR4-3200 ECC RDIMM capacity in a 2Rx4 configuration — providing maximum DDR4 bandwidth at 64GB per-slot density as an alternate part number equivalent to P68070-001, for HPE ProLiant Gen10 Plus servers requiring high-bandwidth DDR4-3200 RDIMM memory for Ice Lake Xeon virtualization, HPC, and in-memory database workloads.
