Targeted Server Upgrade

This 512GB kit contains sixteen 32GB DDR5 4800 registered ECC RDIMMs built for the ThinkMate STX-NL-QE16 E4 nearline storage server. IT teams handling capacity-bound workloads can fill all slots with matched modules in a single order.

Thermals and Power

Each module runs at 1.10V without a heat spreader, relying on the server's directed airflow for cooling. Registered buffering and ECC circuitry add minimal overhead, keeping power draw predictable under sustained load.

Included Modules Only

The package delivers the sixteen RDIMMs and nothing else — no software, cables or additional hardware. Compatibility is validated for the target platform, so installation proceeds by following the system manual's population rules.

Questions about this item

How are the sixteen 288-pin DDR5 RDIMM modules installed in the ThinkMate STX-NL-QE16 E4 server?

Power down the server, open the chassis, locate the memory slots, align each module's notch with the slot key, press firmly until the ejector clips lock on both sides, then close the chassis and power on; the step often missed is verifying the correct population order in the system manual for 16 modules.

What maintenance or replacement will this 512GB DDR5 ECC registered memory kit need later?

No routine maintenance is required; the modules have no heat spreaders to clean, and ECC corrects single-bit errors on the fly, so replacement is only needed if a module fails, which is covered by the manufacturer's lifetime replacement warranty.

What limit appears first under sustained load with these CL40 1.10V 2Rx8 modules?

The CAS latency of CL40 at 4800 MT/s sets the timing boundary, and the registered buffer adds one cycle of command delay, so sustained throughput is capped by the DDR5-4800 specification rather than voltage or thermal throttling.
