Server-grade DDR4 256GB kit

This 256GB kit contains eight 32GB modules built for servers and workstations that require DDR4 ECC Load Reduced DIMMs. It is not compatible with desktop or laptop computers. Each module runs at DDR4 2400 with CL17 latency and standard 1.20V operation. The quad-rank 4Rx4 organisation suits platforms designed for high-density registered memory.

Sustained-load behaviour

Load Reduced DIMMs reduce electrical loading on the memory bus, allowing all eight modules to operate at rated speed without the signal degradation that limits standard registered DIMMs at high population. ECC corrects single-bit errors in real time, maintaining data integrity during continuous workloads. The 1.20V supply keeps power draw predictable across full channels. CL17 timing delivers consistent latency under heavy multi-threaded demand.

Build and connectivity

Every module uses a 288-pin DIMM form factor with major-brand chips tested to A-Tech quality standards. The 4Rx4 quad-rank layout fits server boards that support Load Reduced memory topology. Installation follows the system manual's channel and population rules for optimal throughput. The kit ships new with a lifetime warranty and US-based technical support.

Questions about this item

How much heat and power draw should I expect from eight 32 GB LRDIMMs running at 1.20 V all day?

Each module operates at the standard DDR4 voltage of 1.20 V. Load-reduced DIMMs lower the electrical load on the memory bus, which helps keep power draw and heat lower than equivalent quad-rank registered DIMMs under sustained server workloads.

What must my server already support to use this 256 GB kit of 288-pin DDR4 2400 ECC LRDIMMs?

The system must accept DDR4 ECC load-reduced DIMMs, provide 288-pin slots wired for quad-rank x4 modules, and have a memory controller qualified for 4Rx4 population rules at 2400 MHz.

Can I mix these 4Rx4 PC4-19200L modules with older dual-rank DDR4 RDIMMs already installed?

Mixing load-reduced and registered DIMMs is not supported; the memory controller treats them as different technologies. All slots should be populated with identical 4Rx4 LRDIMMs for stable operation.
