Server kit capacity and purpose

This A-Tech kit supplies 256 GB of DDR4 server memory as two 128 GB LRDIMM modules. It is built for DDR4-compatible servers and workstations that require ECC load-reduced DIMMs and will not work in desktop or laptop systems.

Sustained-load behaviour

The modules run at 2666 MHz with CL19 latency and 1.20 V, using 3DS/TSV octal-rank organisation to keep electrical loading low on the memory bus. ECC and load-reduced buffering maintain data integrity and signal stability during extended, high-capacity workloads.

Pre-purchase checks

Verify that your platform supports DDR4 288-pin LRDIMMs at 2666 MHz and accepts 2S4Rx4 (8Rx4) rank configurations. Consult the system manual for correct slot population rules and maximum supported capacity per channel before ordering.

Domande su questo articolo

How much power does each 128GB module draw at 1.2V during continuous server workloads?

Each module operates at the standard DDR4 voltage of 1.2V; exact power draw depends on the server platform and workload intensity.

What server platform and memory slots are required to install this 256GB DDR4 2666 LRDIMM kit?

This kit requires a DDR4 server or workstation motherboard with 288-pin DIMM slots that explicitly support Load Reduced ECC memory at 2666 MHz.

Can these octal-rank 128GB LRDIMMs be mixed with existing DDR4 RDIMMs in the same server?

Mixing LRDIMMs with standard RDIMMs is not supported; all populated slots must use the same Load Reduced ECC module type for stable operation.
