Server Memory Kit

This 1 TB quad-channel kit contains four 256 GB DDR4 ECC LRDIMM modules built for servers and workstations that require registered load-reduced memory. It is not compatible with desktop or laptop computers.

Thermals and Power

Modules operate at the standard DDR4 voltage of 1.20 V and have no heat spreaders. The load-reduced buffer reduces electrical load on the memory controller, helping to keep power draw and thermals within normal server limits during sustained workloads.

Rank and Pinout

Each module uses a 288-pin DIMM form factor with 2S4Rx4 octal-rank x4 3DS/TSV organisation. The system memory controller must support this specific rank structure and LRDIMM protocol for the kit to function.

Questions sur cet article

How do I install these 288-pin DDR4 LRDIMM modules and which step is most often missed?

Power off the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that all four 256GB modules are detected at 3200 MHz; the step most often missed is checking the system manual for the correct quad-channel population order.

What maintenance or replacement will this 1TB ECC LRDIMM kit need over its service life?

No routine maintenance is required; the modules have no heat spreader and run at 1.20V, so keep server airflow clean and monitor ECC corrected-error counts — replace a module only if uncorrectable errors appear or the system logs a DIMM failure.

What is the first limit that appears when this octal-rank 3DS memory runs under sustained heavy load?

The CAS latency of CL22 at 3200 MHz sets the timing ceiling; under sustained load the memory controller's rank-to-rank switching latency and thermal throttling of the dense 3DS/TSV stacks become the limiting factors before bandwidth saturates.
