High-Capacity Server Memory

The A-Tech 256GB DDR4 3200MHz ECC LRDIMM module targets servers and workstations that require maximum memory density in a single slot. It serves administrators upgrading compatible Samsung platforms who need to expand capacity for virtualisation or large datasets. This module is not suited for consumer desktops or laptops that cannot accept load-reduced registered DIMMs or ECC functionality.

DDR4 3200 Interface Limits

The module operates at DDR4 3200 (PC4-25600) with a CAS latency of 22 and a standard voltage of 1.20V. System memory controllers must support the 2S4Rx4 (8Rx4) rank structure and 3DS/TSV stacking for full capacity recognition. Platforms limited to lower rank counts or standard RDIMM topology will not utilise this module. Buyers must verify motherboard qualification lists before purchase.

Load-Reduced Build and Connectors

Built with Samsung chipset components, the load-reduced design reduces electrical load on the memory bus to enable high-density population. The 288-pin DIMM form factor fits standard DDR4 server slots, though the supplier notes a 262-pin reference in documentation. Rigorous quality assurance testing validates reliability for continuous operation in qualified systems.

Preguntas sobre este artículo

Should I choose the 256GB module or a different capacity for my server?

This listing is for a single 256GB module. Select it when your server requires maximum density per DIMM slot and supports 256GB LRDIMMs.

What does the 3200MHz speed mean for actual server workloads?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency, delivering high bandwidth for virtualization, databases, and multi-threaded applications on compatible platforms.

How does the ECC LRDIMM interface affect compatibility and capacity limits?

It uses a 288-pin DDR4 LRDIMM form factor with load-reduced buffering and 8Rx4 3DS/TSV ranks, allowing higher capacities per channel on supported server motherboards.
