Server-grade capacity

This 2 TB kit contains eight 256 GB DDR4 modules rated at 3200 MHz with PC4-25600 bandwidth. Each stick operates at 1.2 V and presents an 8Rx4 organisation with ECC and registered buffering. It is built for enterprise servers that require maximum memory density and error correction.

Platform integration

The registered design places a buffer between the modules and the memory controller, reducing electrical load on the server platform. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. The kit requires a motherboard with 288-pin DDR4 slots that support registered ECC RDIMMs and the 8Rx4 rank configuration.

Ready-to-deploy kit

Eight matched modules ship together, eliminating the need to source individual sticks and validate mixed ranks. Uniform CAS latency of 22 across the set simplifies BIOS configuration and avoids timing mismatches. Major-brand Samsung, Micron or Hynix DRAM ensures consistent quality throughout the kit.

Questions about this item

Will the CAS latency of 22 become a bottleneck under sustained heavy workloads?

The modules run at CL22 timing at the rated 3200 MT/s speed, which is the standard latency for this DDR4 server grade and does not introduce an additional bottleneck beyond the spec.

How much heat and power will eight 256 GB registered DIMMs draw when the server runs continuously?

Each DIMM operates at 1.2 V; total power scales with the number of active ranks, so eight 8Rx4 modules will draw more power and generate more heat than a smaller kit, requiring adequate chassis airflow.

What motherboard features are required for this 2 TB kit to function?

The system must provide 288-pin DDR4 slots that support registered ECC RDIMMs, 8Rx4 rank configuration and a memory controller able to address 256 GB per module.
