128GB DDR5 ECC RDIMM Kit

This 128GB kit contains eight 16GB DDR5 6400MHz registered DIMMs built for server platforms. It targets administrators upgrading or populating enterprise systems that require error-correcting memory. The modules operate at 1.1V with a CAS latency of 52.

Registered ECC with 1Rx8 organisation

The defining specification is the registered ECC design combined with a single-rank 1Rx8 layout. This configuration ensures signal integrity and data integrity on compatible server motherboards. Systems that accept only unbuffered non-ECC memory cannot use these modules.

288-pin DDR5 server installation

Each module uses the standard 288-pin DDR5 form factor and draws 1.1V. The kit fills eight DIMM slots, so the host board must provide at least eight DDR5 RDIMM sockets. It frees the builder from mixing capacities or speeds across channels.

Questions about this item

What does the 6400MHz DDR5 speed mean for real server workloads?

The kit runs at DDR5 6400 (PC5-51200) with CAS latency 52, delivering high bandwidth for memory-intensive server applications.

How does the ECC RDIMM registration affect compatibility and data integrity?

Registered ECC RDIMM design adds a register between the DRAM and memory controller, enabling error correction and supporting higher module counts per channel in qualified server platforms.

What physical slot and module count does this 128GB kit require?

Eight 288-pin DDR5 RDIMM slots are needed; each 16GB module is single-rank 1Rx8 at 1.1V.
