64GB DDR5 ECC RDIMM kit for ThinkMate towers

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs built for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers. Each module runs at 1.1V with CL40 latency and provides error-correcting code protection. The registered design reduces electrical load on the memory controller for stable operation in multi-DIMM configurations.

Sustained throughput with registered buffering

Registered buffering and ECC maintain data integrity during continuous server workloads such as virtualization, database hosting and file serving. The 1Rx8 organisation keeps each rank simple while the 4800 MT/s transfer rate feeds multi-core processors without bottlenecks. Operation at the standard 1.1V DDR5 voltage avoids excess heat during long uptime periods.

288-pin modules without heat spreaders

Bare 288-pin RDIMMs fit directly into standard DDR5 server slots and leave maximum clearance for CPU coolers or chassis airflow. Samsung, Micron or Hynix DRAM chips are selected by the assembler to meet the stated specifications. Builders who need more than four modules per channel or who require consumer desktop compatibility should choose a different product.

Questions about this item

Does the 1.1V DDR5 4800 kit run cooler than higher-voltage server memory during continuous operation?

Operating at 1.1V, these registered DDR5 modules draw less power per stick than higher-voltage alternatives, reducing heat output in a fully populated ThinkMate tower server running all day.

My ThinkMate TWX-QS8-14E4 has empty DIMM slots — is anything else required to install this 4x16GB kit?

The motherboard must support DDR5 4800 registered ECC RDIMMs; no extra cables, brackets or cooling accessories are needed beyond the four 288-pin slots.

Will these CL40 1Rx8 modules work alongside the original 16GB sticks already in my ThinkMate TWX-QS8-24E4?

Mixing ranks or speeds can prevent the server from posting; for stability, replace the existing memory with this matched 64GB kit rather than combining them.
