512 GB DDR5 RDIMM kit for ThinkMate servers

This 512 GB kit contains eight 64 GB DDR5 4800 modules built for ThinkMate TWX-XS8 tower servers. Each stick is a registered ECC RDIMM that adds error correction and signal buffering for stable operation under heavy workloads. The memory targets IT teams expanding capacity in compatible ThinkMate platforms.

288-pin registered modules without heat spreaders

Modules use a 288-pin DDR5 RDIMM form factor and run at 1.1 V with CL40 latency. The 2Rx4 organisation and major OEM DRAM from Samsung, Micron or Hynix support reliable data integrity. Absence of heat spreaders keeps the profile low for dense server chassis where airflow is managed by the system fans.

Low-voltage DDR5 reduces power draw at load

Operating at 1.1 V, the kit draws less power per gigabyte than previous DDR generations during sustained throughput. Registered buffering lightens the electrical load on the memory controller, helping system thermals stay predictable in multi-socket configurations. Fan noise remains governed by the server chassis rather than the memory itself.
