HPE-compatible 16 GB DDR4-3200 registered ECC module with 2Rx8 organisation and 1.2 V operation
This 16 GB DDR4-3200 registered ECC module is built for servers that require HPE part number P07642?H21 compatibility. It operates at 1.20 V with a 2Rx8 rank configuration across 288 pins. Major-brand chips from Samsung, SK Hynix or Micron deliver OEM-level reliability for enterprise infrastructure.
Ideal for administrators upgrading or repairing HPE systems that specify PC4-25600 registered memory with ECC. Not suitable for workstations or desktops that require unbuffered non-ECC modules, nor for platforms limited to lower DDR4 speeds or different voltage requirements.
The single specification that determines fit is the 2Rx8 registered ECC organisation running at 1.20 V. Only systems qualified for this exact rank, buffering and voltage combination will recognise and stabilise the module at 3200 MT/s.

The module is rated for DDR4-3200; the final speed depends on the server's memory controller and the total number of DIMMs populated per channel.
PC4-25600 is the JEDEC peak transfer-rate label for DDR4-3200; it confirms the module meets the 3200 MT/s data-rate standard.
Yes, it uses the 288-pin DDR4 RDIMM form factor required by compatible HPE servers.
