System-Specific DDR5 Server Memory Kit

This 1 TB kit contains eight 128 GB registered DDR5 RDIMMs built for Thinkmate HDX-QN8-52E4 high-density servers. It targets IT teams who need maximum capacity per channel in a validated configuration. The modules operate at the standard 1.1 V and carry ECC for data integrity in mission-critical workloads.

4Rx4 Rank Architecture Determines Compatibility

Each module uses a quad-rank 4Rx4 organisation that the memory controller must support natively. Systems limited to dual-rank or single-rank DIMMs will not recognise the full capacity or may fail to post. Verify the platform documentation for 4Rx4 support before purchasing.

Baseline Thermals and Power at 4800 MT/s

Running at 4800 MT/s with CL40 latency, the kit draws 1.1 V per module without additional heat spreaders. Registered buffering reduces electrical load on the memory bus, helping maintain stable temperatures in dense chassis. Acoustic output depends entirely on the server’s own fan curves.

Questions about this item

What does 4800 MT/s mean once the kit is installed in a ThinkMate server?

The modules run at 4800 MT/s with CL40 latency, delivering the rated PC5-38400 bandwidth as long as the platform supports DDR5-4800.

How does the DDR5 RDIMM interface limit performance in this system?

Registered DDR5 adds a clock cycle for command buffering and caps the data rate at the rated 4800 MT/s; ECC and 4Rx4 organisation are handled by the memory controller.

Will the 288-pin 1.1 V modules fit the ThinkMate HDX-QN8-52E4 memory slots?

Yes, the kit uses standard 288-pin DDR5 RDIMM form factor at 1.10 V, matching the server's DIMM sockets and voltage requirements.
