NEMIX RAM
Eight 16 GB DDR5 ECC registered DIMMs deliver 128 GB at 4800 MT/s with CL40 latency and 1.1 V operation
This 128GB kit contains eight 16GB DDR5 registered DIMMs built for the Thinkmate STX-NL-QE16 E4 nearline storage server. Each module runs at 4800 MT/s with CL40 latency and 1.10V voltage. ECC and registered buffering protect data integrity in mission-critical workloads.
Operating at 1.10V, the modules draw minimal power for DDR5 registered memory. No heat spreaders are fitted, so airflow across the 288-pin slots handles cooling. Under typical server loads the kits run quietly within standard chassis fan curves.
The package delivers a matched 8 x 16GB set validated for the target platform, removing the guesswork of mixing modules. Rigorous stress testing under load aims to ensure stability from first boot. Lifetime replacement warranty and US-based IT support back the upgrade.

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then verify all eight 16GB sticks are recognised in the BIOS before closing the case.
The modules have no moving parts or heat spreaders, so no routine maintenance is required; ECC corrects single-bit errors on the fly, and a failed stick is simply replaced with another 1Rx8 4800 CL40 1.1V RDIMM of matching capacity.
The registered buffer and CL40 latency set the throughput ceiling; under continuous heavy load the memory controller hits its maximum sustainable bandwidth before thermal or voltage limits become a factor.
