WHAT YOU NEED TO KNOW
Memory is a hot market right now. DDR5 and DDR4 are extremely volatile with data centers driving availability to extreme lows. Always validate machine type and model. Remember: all RAM is Hynix, Samsung, or Micron underneath OEM labels — use that to find alternatives. Key checks: Check OEM alternatives — all RAM is Hynix/Samsung/Micron underneath. Double-check what you're quoting in volatile market.

PRODUCT OVERVIEW
HP 16GB (1x16GB) 2RX4 PC4-17000P-R DDR4-2133MHZ RDIMM

When you choose HP SmartMemory you get the same high quality, reliability, and confidence that come with your HP ProLiant Gen9 Server series. DRAM quality and reliability are more important now than ever. Industry trends such as server virtualization, cloud computing, the use of large database applications and high-performance computing have all increased the need for higher capacity memory with greater reliability and uptime.

HP SmartMemory is unique technology was introduced in ProLiant Gen8 Servers and in ProLiant Gen9 Servers it unlocks certain features available only with HP Qualified Server memory. HP SmartMemory enables ProLiant Gen9 systems to reliably identify and verify whether installed memory has passed the rigorous HP qualification and testing processes. And because the memory is authenticated, extended memory performance features can be enabled through the system ROM.

This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 7025-01-647-5345, indicating validated use in U.S. government and defense logistics supply chains.
