Micron 16GB DDR4-2133 ECC RDIMM Server Memory

It is a registered DIMM (RDIMM). A register on the module buffers command and address signals between the memory controller and DRAM chips, reducing load on the memory channel. This is the standard type for dual-socket Xeon servers. RDIMMs will not work in desktop systems or servers that only accept unbuffered DIMMs, so check that your platform supports DDR4 registered ECC memory before ordering.

Dell PowerEdge 13th generation servers such as the R630 and R730 use DDR4 ECC registered DIMMs, and DDR4-2133 is a speed these Xeon E5 v3 and v4 systems are designed around. This module matches that memory type. Follow Dell's population guidelines for channel order, and avoid mixing RDIMMs with LRDIMMs in the same server.

HPE ProLiant Gen9 models such as the DL360 Gen9 and DL380 Gen9 use DDR4 registered ECC memory on Intel Xeon E5 v3 and v4 processors, which is the memory type this module provides. Some HPE systems may display a notice for non-HPE branded memory at boot. Populate DIMMs according to HPE's slot guidelines for each processor.

PC4-2133 identifies a DDR4 module running at 2133 megatransfers per second. PC4-17000 is the equivalent naming based on peak module bandwidth of roughly 17,000MB/s. Both labels describe the same speed grade. The PC4 prefix confirms DDR4, so this module is not compatible with DDR3 (PC3) slots, which use a different pin count and key position.

Most servers will accept mixed DDR4 RDIMM speeds, but the memory controller generally runs all installed modules at the speed of the slowest one, so a mix would operate at 2133MT/s. For predictable behaviour it is best to keep capacity, rank and speed matched within each channel and follow your server vendor's population rules.

Generally not. Mainstream desktop processors and motherboards support unbuffered DDR4 and do not accept registered DIMMs, even though the 288-pin connector is the same. This module is intended for server and workstation platforms whose memory controllers support registered ECC DDR4, such as systems built on Intel Xeon E5 v3 and v4 processors.

ECC, or error-correcting code, allows the memory system to detect and automatically correct single-bit errors and detect multi-bit errors. In servers that run continuously, that helps prevent silent data corruption, application crashes and unexpected reboots. It is particularly valuable on virtualisation hosts, databases and storage servers where memory holds large volumes of active data.
