256GB DDR5 RDIMM kit for Thinkmate HDX-QN8-52E4

This 256GB kit contains four 64GB DDR5 4800 registered ECC modules built for the Thinkmate HDX-QN8-52E4 high-density server. It targets IT teams who need maximum memory capacity in a validated configuration for mission-critical workloads.

DDR5 4800 registered ECC limits

The DDR5 4800 standard runs at 1.10V with a CL40 latency and 2Rx4 organisation. Registered DIMMs add a clock cycle for buffering, which stabilises large populations but caps peak bandwidth compared to unbuffered memory. Four modules fill the typical channel limit for this platform.

Installation notes for 288-pin RDIMMs

The 288-pin DDR5 RDIMMs key into the server slots in one orientation. Align the notch, press evenly until the ejectors latch, and verify population order in the system manual. Mismatched ranks or mixing registered with unbuffered modules will prevent boot.
