A-Tech 64GB DDR4 2133MHz LRDIMM

This 64GB DDR4 LRDIMM module runs at 2133MHz with CL15 latency and 1.20V operation. It uses a 4Rx4 quad-rank layout and ECC load-reduced technology for server platforms. The 288-pin form factor fits compatible DDR4 server memory slots. Supermicro certification confirms validated compatibility with qualified systems.

Thermals and power in normal use

Operating at the standard 1.20V DDR4 voltage, the module draws minimal power during typical server workloads. Load-reduced buffering reduces electrical load on the memory controller, helping maintain stable thermals. ECC error correction runs transparently without adding measurable latency or heat in everyday operation.

Behaviour under sustained load

The 4Rx4 quad-rank organisation allows high-density capacity while the load-reduced design keeps signal integrity stable during extended sessions. ECC continuously corrects single-bit errors to prevent data corruption over long runtimes. Supermicro certification testing verifies reliable performance under continuous server duty cycles.

Questions sur cet article

How do I install the 288-Pin LRDIMM and what step is often missed?

Align the notch on the 288-Pin LRDIMM with the motherboard slot key, press down firmly until both retention clips click, and verify the system detects the full 64GB at 2133MHz in BIOS.

What maintenance or replacement will this ECC Load Reduced module need over time?

No routine maintenance is required; if a correctable error count rises or the module fails, replace the 64GB stick with an identical DDR4 2133 CL15 1.2V 4Rx4 LRDIMM to maintain matched ranks.

What limit appears first when this quad-rank memory runs sustained workloads?

The 4Rx4 organisation increases electrical loading, so the memory controller typically hits its maximum supported rank count or per-channel capacity before bandwidth or thermal limits become an issue.
