Frequently Asked Questions

Is P43333-1A1 interchangeable with P62604-B21?

Yes — P43333-1A1 is the regional/revision variant and P62604-B21 is the option kit. Both are HPE 64GB DDR5-4800 EC8 Registered DIMM 2Rx4 CL40 1.1V modules with identical specifications — fully interchangeable in supported HPE ProLiant Gen11 EC8 DDR5-4800 configurations.

What is the difference between DDR5-4800 and DDR5-6400 EC8 RDIMMs?

DDR5-4800 (PC5-38400) runs at 4800MHz for ~76.8 GB/s peak bandwidth, validated for Xeon Scalable 4th Gen (Sapphire Rapids). DDR5-6400 (PC5-51200) runs at 6400MHz for ~102.4 GB/s, validated for Xeon Scalable 5th Gen (Emerald Rapids). Use DDR5-4800 for 4th Gen Sapphire Rapids platforms and DDR5-6400 for 5th Gen Emerald Rapids Gen11 platforms.

Does EC8 affect DDR5-4800 memory performance?

EC8 provides multi-bit error correction with negligible memory bandwidth overhead for most enterprise workloads. The trade-off is significantly stronger data integrity for mission-critical applications requiring beyond-standard ECC protection at DDR5-4800 speeds.
