128GB DDR4 2133 ECC Registered Kit

This 128GB kit contains two 64GB DDR4 2133 (PC4 17000) LRDIMMs. Each module is a 288-pin registered DIMM with ECC and a 4Rx4 organisation. It is built for servers and workstations that require registered memory with error correction.

DDR4 2133 registered interface limits

The DDR4 2133 standard caps the data rate at 2133 MT/s, so bandwidth is lower than faster DDR4 grades. Registered buffering adds one clock cycle of latency and the memory controller must support registered DIMMs; unbuffered consumer platforms cannot use these modules.

128GB capacity and 4Rx4 headroom

Two 64GB ranks provide 128GB total, suited to virtualisation hosts or databases that benefit from large memory footprints. The 4Rx4 organisation places four ranks per DIMM, so a four-slot channel reaches its rank limit with only two modules, restricting further expansion on dense platforms.

Questions about this item

Should I pick the 2×64GB kit or buy single 64GB modules for my server?

The kit is sold as a matched 2×64GB pair totalling 128GB; using the paired modules ensures identical timings and rank configuration across both slots.

What does the DDR4 2133 (PC4 17000) rating mean once the memory is installed?

The modules run at 2133 MT/s with a peak bandwidth of 17000 MB/s per module, delivering that throughput when the platform operates at the rated speed.

How does the 288-pin DDR4 registered ECC interface affect compatibility?

The 288-pin registered ECC DDR4 LRDIMM form factor only fits server boards that support registered error-correcting DDR4 memory; it will not work in standard desktop sockets.
