8GB DDR4 2133MHz ECC RDIMM Server Memory

This 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.20V operation. It is a registered ECC DIMM built with a 1Rx8 configuration using Micron chipset components. The 288-pin form factor fits standard DDR4 server and workstation slots.

Suited for servers and workstations requiring

This module fits systems that specifically call for DDR4 2133MHz RDIMM modules with ECC and registered buffering. It is not for desktop PCs that accept only unbuffered non-ECC UDIMMs. It is also not for platforms needing higher speeds, larger capacities per slot, or different rank configurations.

Verify your system supports DDR4 2133MHz

Check the motherboard or server documentation for qualified memory lists that include 1Rx8 registered modules at this speed. Confirm the platform accepts 1.20V DDR4 DIMMs and that the memory controller supports ECC functionality. Ensure the 288-pin DIMM slot is the correct physical interface before ordering.

Questions about this item

Does my server motherboard need a 288-pin DDR4 DIMM slot to accept this module?

Yes, the module is a 288-pin DDR4 DIMM designed for server and workstation boards that support registered ECC memory.

Can I install this 1Rx8 registered ECC RDIMM alongside existing unbuffered non-ECC DIMMs in the same system?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC modules; the memory controller requires all installed DIMMs to share the same registered ECC configuration.

How do I confirm the module is running at 2133 MT/s with CL15 latency after installation?

Check the BIOS memory information or a system utility such as CPU-Z; it should report DDR4-2133, PC4-17000, CAS latency 15, and 1.20 V operation.
