What servers is the HPE P71561-001 compatible with?

Compatible with HPE ProLiant Gen11 servers including DL360 Gen11, DL380a Gen11, ML350 Gen11, and DL320 Gen11. Follows official memory population guidelines with 1,2,4,6,8,12 DIMMs per socket for balanced performance.

What are the exact speed and latency specs?

DDR5-5600 MT/s with CAS timings 46-45-45 and EC8 error correction. Operates at full speed in 1DPC configurations with 4th/5th Gen Intel Xeon or 4th Gen AMD EPYC processors.

Does this module support mixing with other sizes?

HPE recommends uniform DIMM sizes and speeds for optimal performance. Mixing results in all modules operating at the slowest common speed per HPE Gen11 memory population rules.

What makes HPE Smart Memory different?

Includes silicon-level health monitoring, predictive failure alerts via iLO, and automatic inventory. Provides higher reliability than third-party memory with HPE-exclusive RAS features.

What is the maximum capacity per server?

Up to 8TB using 256GB 3DS RDIMMs across 64 slots in 4-socket DL560 Gen11. This 128GB module enables 2TB at 1DPC or 4TB+ at 2DPC configurations.

Is this module hot-plug supported?

Memory population requires server power-off for installation per HPE guidelines. Online sparing and patrol scrub features provide runtime error mitigation once installed.
