System-specific DDR5 kit

This NEMIX RAM kit provides 256 GB of DDR5 4800 memory in eight 32 GB registered DIMMs. It is built for the Thinkmate STX-NL-QE16 E4 nearline storage server. The modules carry ECC and operate at 1.1 V with CL40 latency.

Registered ECC for server boards

Each 288-pin RDIMM uses a 2Rx8 organisation and registered buffering to maintain signal integrity on loaded channels. The kit fills all eight slots of the target platform without requiring mixed capacities. No heat spreaders are fitted, so airflow must come from chassis fans.

Low-voltage DDR5 operation

Running at 1.1 V keeps power draw modest for a 256 GB configuration. Registered modules add negligible latency overhead while the ECC engine corrects single-bit errors transparently. Sustained throughput depends on the server memory controller and workload profile.

Questions about this item

Does the 2Rx8 organisation on all eight modules limit how many ranks the memory controller can address?

Each 32 GB module is dual-rank 2Rx8, so the kit presents sixteen ranks to the controller. Verify the ThinkMate STX-NL-QE16 E4 maximum rank count before populating all eight slots.

What is the continuous power draw of the kit at the rated 1.1 V?

Registered DDR5 RDIMMs at 1.1 V typically draw a few watts per module under load; the exact figure depends on the ThinkMate platform's memory-subsystem design and airflow.

Which motherboard feature must already be present for ECC correction to function?

The server motherboard must implement DDR5 ECC RDIMM support in its chipset and BIOS; without that hardware feature the modules will not provide error correction.
