HPE 32GB DDR4-2666 ECC RDIMM
This HPE 815100-B21 module provides 32GB of DDR4 memory rated at 2666 MT/s with PC4-21300 bandwidth. It uses a 2RX4 organisation and includes ECC for error correction in compatible server platforms. The registered design helps signal integrity on multi-DIMM channels. It is suited for administrators upgrading HPE ProLiant systems that require registered ECC memory.
Installing the registered ECC RDIMM
Installation follows standard DIMM-slot procedure: align the notch, press firmly until the latches click, and verify seating. The module will only function in platforms that support registered DDR4 ECC and the 2RX4 rank configuration. It will not work in desktop boards that accept only unbuffered non-ECC memory or that lack support for this rank structure. Ensure the system BIOS recognises the full 32GB capacity after installation.
