The HPE 845264-B21 is a 16 GB Single Rank x4 DDR4-2666 NVDIMM module kit that combines high-speed DRAM with flash persistence to protect data during power loss.
The 845264-B21 NVDIMM kit is certified for HPE ProLiant Gen10 and Gen10 Plus servers equipped with DDR4-2666 DIMM slots and NVDIMM firmware support.
This NVDIMM delivers 16 GB capacity, DDR4-2666 MT/s speed, single rank x4 organization, 1.2 V operating voltage, and onboard flash for persistence.
Unlike RDIMMs, HPE NVDIMMs combine DRAM performance with nonvolatile flash backup to preserve data in the event of power loss.
Flash persistence ensures that data in DRAM is automatically written to onboard flash during an outage, guaranteeing data integrity on reboot.
Power down your server, open the DIMM bay, align the module’s notch with the slot key, press firmly until latched, then close and power on.
No, HPE NVDIMMs require a shutdown for safe installation and removal to ensure proper persistence and avoid data loss.
Install HPE iLO and server BIOS firmware version 2.00 or later to enable full NVDIMM functionality and monitoring.
No external power module is needed; the kit uses server-provided power and onboard capacitors to transfer data to flash.
Experience DRAM-level latency with the added benefit of nonvolatile data protection, reducing data-recovery times after power events.
The 845264-B21 operates between 0 °C and 35 °C at 10%–90% non-condensing humidity in a standard server environment.
Use HPE Smart Memory and server BIOS diagnostics to confirm the NVDIMM status, capacity, and persistence health.
HPE provides a limited lifetime warranty on this NVDIMM kit when installed in a supported HPE server under normal operating conditions.
Yes, you can mix NVDIMMs and RDIMMs in the same server, but ensure correct slot population per the HPE memory population guidelines.
Order directly from HPE authorized resellers or HPE’s official e-commerce portal using SKU 845264-B21 for guaranteed authenticity.
