256 GB DDR4 ECC LRDIMM kit

This 256 GB kit contains eight 32 GB DDR4 2400 MHz modules built for servers and workstations that require ECC load-reduced memory. The dual-rank x4 organisation and registered buffer suit multi-socket platforms needing large capacities per channel. It is not compatible with desktop or laptop computers. Verify your system's qualified vendor list before purchase.

Sustained throughput with ECC LRDIMM

Load-reduced DIMMs reduce electrical load on the memory bus, allowing all eight modules to run at the rated 2400 MHz under continuous workloads without the signal degradation seen on standard registered DIMMs at high population. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute jobs. CL17 latency at 1.20 V keeps power draw predictable across fully populated channels.

288-pin build quality and daily handling

Each module uses major-brand chips mounted on a 288-pin PCB tested through A-Tech's validation process before shipping. The LRDIMM form factor fits standard DDR4 server slots but requires motherboard support for load-reduced operation; mixing with RDIMM or UDIMM is not supported. Handle modules by the edges and seat firmly until the ejector clips latch to ensure reliable contact in vibration-prone rack environments.

Questions about this item

How much power does the 1.20V DDR4 2400 kit draw under sustained server loads?

Each module runs at the standard 1.20V DDR4 voltage; total system draw depends on the platform's memory controller and how many of the eight 32GB LRDIMMs are populated.

What must my motherboard provide to run these 288-pin ECC LRDIMMs?

The board needs DDR4 server memory slots that support 288-pin LRDIMMs with ECC and load-reduced signalling; desktop or laptop platforms will not accept them.

Will the 2Rx4 dual-rank modules work alongside older single-rank DDR4 DIMMs I already have?

Mixing 2Rx4 LRDIMMs with single-rank DIMMs is platform-dependent; consult the server or workstation manual for qualified population rules before combining them.
