Server-grade capacity and ECC reliability

This 256 GB kit provides two 128 GB DDR4 modules built for servers and workstations that require error-correcting memory. The load-reduced design lowers electrical load on the memory bus, allowing higher densities than standard registered DIMMs. It is intended for administrators expanding memory in compatible enterprise platforms.

Dual-channel kit with 288-pin DDR4 interface

The pair installs as a matched dual-channel set into 288-pin DDR4 slots that support LRDIMM modules. Each stick operates at 1.20 V and uses 3DS/TSV quad-rank organisation, so the platform must explicitly accept 2S2Rx4 ECC LRDIMMs. No heat spreader is fitted, leaving clearance for dense slot populations.

Sustained throughput at CL22 latency

Rated at 3200 MHz with CAS latency 22, the modules deliver steady bandwidth for virtualisation, database and compute workloads that run continuously. The major-brand chips and full ECC coverage maintain data integrity over long periods without the error accumulation seen in non-ECC memory.

Questions sur cet article

Will the 1.20 V voltage limit thermal throttling under sustained load?

The modules run at standard 1.20 V DDR4 voltage with no heat spreader, so sustained use relies on server airflow rather than onboard cooling.

How much noise or heat does the quad-rank 3DS design add during all-day operation?

Load-reduced ECC LRDIMMs draw standard 1.2 V power and produce no extra fan noise; thermal output matches other DDR4 3200 server modules.

My motherboard needs 288-pin DDR4 ECC LRDIMM slots — what else must I already have?

A DDR4 server or workstation platform that supports 128 GB per slot, quad-rank 3DS/TSV organisation and registered ECC memory.
