ThinkMate DDR5 4800 server kit

This 256GB kit contains two 128GB DDR5 4800 RDIMM modules built for ThinkMate HDX-QN8-52E4 high-density servers. Registered ECC circuitry protects data integrity in mission-critical workloads. The modules run at 1.1V with a CL40 latency profile.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC corrects single-bit errors on the fly without halting the system. Major OEM Samsung, Micron or Hynix DRAM chips are stress-tested under load before shipping.

Installation notes

The 288-pin DDR5 form factor seats in standard RDIMM slots; no heat spreader is fitted, so clearance is minimal. Verify the server BIOS supports 4Rx4 128GB modules before installation. Mixing with different ranks or speeds will prevent the system from posting.

Questions about this item

How much power does the 1.1V DDR5 4800 kit draw under sustained server loads?

Each module runs at 1.1V; total draw depends on the platform's memory controller and workload, so consult the THINKMATE HDX-QN8-52E4 documentation for exact figures.

What motherboard features are required for these 4Rx4 ECC RDIMMs to function?

A DDR5 RDIMM slot supporting 288-pin registered ECC modules at 4800 MT/s with 4Rx4 organisation and 1.1V operation.

Will the CL40 4Rx4 modules run stably in a THINKMATE HDX-QN8-52E4 populated with older DDR5 DIMMs?

Mixing ranks or speeds forces the system to run at the lowest common speed and loosest timings; populate identical kits for guaranteed stability.
