Server-grade memory kit

This 384 GB kit contains four 96 GB DDR5 4800 registered DIMMs built for ThinkMate TWX-QS8 tower servers. Each module operates at 1.1 V with CL40 latency and includes on-die ECC for data integrity. The 2Rx8 organisation and 288-pin RDIMM form factor match the qualified platform specification.

Suited for capacity-bound workloads

IT teams expanding virtualisation hosts, database nodes or analytics clusters on the listed ThinkMate models can install this kit without mixing module sizes. Builders using desktop motherboards, workstations without RDIMM support or systems limited to lower maximum memory per slot should select a different product.

Registered ECC RDIMM with 2Rx8 layout

The modules are buffered and error-correcting, so the memory controller must support registered signalling and ECC scrubbing. Consumer platforms and unbuffered-only servers will not recognise the kit, making the registered ECC RDIMM attribute the single compatibility gate.

Questions about this item

Will the 96GB DDR5 modules need replacement after a certain number of years?

The modules are new and carry a lifetime replacement warranty from NEMIX RAM, so no scheduled replacement is required.

What limits sustained throughput on the 4800MHz CL40 kit?

The CAS latency of CL40 and the 4800MT/s data rate set the ceiling for continuous bandwidth.

How much heat and power do the four 1.1V registered DIMMs produce under all-day load?

Each 2Rx8 RDIMM runs at 1.10V without a heat spreader, so total power draw stays low and passive airflow in the server chassis handles cooling.
