Server RDIMM for HP systems

This 16GB DDR4-2666 module is built for HP-compatible servers that require ECC registered memory. It suits administrators expanding capacity in existing rack or tower deployments where data integrity and uptime are priorities.

Registered design with major-brand chips

The stick uses Samsung, SK Hynix or Micron components and meets OEM specifications for the 838081-B21 part number. Its 288-pin RDIMM form factor, 1.2V operation and CL15 latency match the platform's electrical and timing requirements for stable daily operation.

Verify DDR4 RDIMM slot availability

Confirm the server accepts 1Rx4 registered DDR4 modules at 2666 MT/s before ordering. Systems limited to unbuffered UDIMMs, lower speeds or different rank configurations will not support this module.
