A-Tech 256GB DDR4 3200 ECC LRDIMM Kit

This A-Tech kit supplies 256 GB of DDR4 server memory across four 64 GB load-reduced DIMMs. Each module runs at 3200 MHz with CL22 latency at the standard 1.20 V. The 4Rx4 quad-rank organisation and ECC function are built for registered DDR4 platforms that require LRDIMM technology.

For DDR4 servers and workstations needing maximum

Suits administrators expanding memory in systems qualified for DDR4 ECC LRDIMM modules. Not for desktop or laptop computers, which cannot accept 288-pin registered LRDIMMs. Also unsuitable for platforms limited to standard RDIMM or UDIMM populations, or for any system that does not support quad-rank x4 memory.

Quad-rank 4Rx4 load-reduced organisation

The 4Rx4 configuration places four logical ranks on each DIMM, allowing the kit to reach 256 GB in only four slots. This rank density is the decisive factor: the host platform must explicitly support 4Rx4 LRDIMMs, otherwise the modules will not be recognised or will operate at reduced capacity.

Questions sur cet article

Will the 4Rx4 quad-rank LRDIMM modules need firmware updates or replacement after prolonged server use?

The modules are tested for dependable operation at DDR4 3200 CL22 1.20 V; no firmware updates are required and replacement is only needed if a module fails.

What limit appears first when the 256 GB kit runs at full 3200 MHz load continuously?

The CL22 latency at 1.20 V sets the timing ceiling; sustained throughput is bounded by the DDR4 3200 specification.

How much heat and noise do the four 64 GB LRDIMMs generate during all-day operation?

Standard 1.20 V DDR4 voltage keeps power draw low; the modules are passive with no fans, so they add negligible noise and minimal heat to the server chassis.
