128GB DDR4 2133 ECC RDIMM Server Kit

This 128GB kit contains eight 16GB DDR4 2133 MHz registered DIMMs with ECC. It is built for servers and workstations that require registered memory with error correction. The modules run at 1.2V with CL15 latency. Desktop and laptop systems cannot use these modules.

Who this suits and who it does not

This kit suits administrators upgrading DDR4 servers or workstations that support registered ECC DIMMs and dual-rank x4 modules. It is not for buyers who need unbuffered memory, non-ECC modules, or a different speed grade. It is also not for desktop or laptop owners.

Registered ECC with dual-rank x4 organisation

Each module is a 288-pin DDR4 RDIMM organised as 2Rx4 with on-die ECC and registered buffering. This combination decides whether the memory will initialise on a given server platform. Verify that your system accepts registered dual-rank x4 DDR4 2133 before purchasing.

Questions about this item

What motherboard slot and memory standard does this 288-pin DDR4 RDIMM kit require to operate?

The modules need a server or workstation motherboard with DDR4 288-pin RDIMM slots; desktop or laptop boards will not accept them.

Will these 2Rx4 registered ECC modules run in a system that currently uses 1Rx8 unbuffered DDR4 memory?

No, the registered ECC design and dual-rank x4 organisation are incompatible with unbuffered consumer memory; all slots must use matching RDIMM modules.

How can I confirm the kit is running at the rated 2133 MT/s with CL15 timings after installation?

Check the BIOS memory information or a tool such as CPU-Z to verify the speed shows DDR4-2133 and the CAS latency reads 15.
