256GB DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 4800 CL40 registered DIMMs built for the Thinkmate GPX-WS-740RTP7 workstation. The modules run at 1.1V with on-die ECC and a 2Rx8 organisation for server-grade data integrity.

Registered ECC changes system behaviour

Registered buffering reduces electrical load on the memory controller so all eight modules can operate together at the rated 4800 MT/s. ECC corrects single-bit errors and detects multi-bit errors without software intervention, protecting long-running workloads.

Install in matched-channel order

The 288-pin DDR5 modules key only one way into the workstation slots; seat each DIMM until the latches click. Populate channels in the sequence shown in the system manual to avoid a no-post condition caused by incorrect population order.

Questions about this item

Will the eight 32GB DDR5 modules need any periodic maintenance or component replacement once installed?

The modules are solid-state with no moving parts or user-serviceable components; they require no scheduled maintenance and are covered by a lifetime replacement warranty.

What is the first limit reached when the 256GB kit runs at DDR5 4800 CL40 under sustained load?

The registered ECC design and 1.10V operation keep electrical and thermal limits well above typical workstation workloads, so the practical ceiling is the platform's memory-controller bandwidth at 4800 MT/s.

How much heat and power does the 8-module kit produce when the workstation runs all day?

Each 32GB RDIMM draws 1.10V with no heat spreader, so total power scales with the eight modules and system airflow handles the resulting heat without additional cooling.
