256GB DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for ThinkMate RAX-XS4-21S4 rackmount servers that require registered memory. The modules operate at 1.1V and use 288-pin DDR5 form factor. IT teams needing maximum capacity in compatible slots will use this kit.

Sustained load behaviour

Registered buffering and on-die ECC maintain data integrity during continuous server workloads. The 2Rx8 organisation spreads access across ranks to reduce per-rank pressure. Samsung, Micron or Hynix major-OEM chips are stress-tested under load before shipping. The 1.1V operating voltage keeps power draw steady during extended operation.

DDR5 4800 interface limits

The PC5-38400 standard caps transfer rate at 4800 MT/s per pin. CL40 timing sets the minimum latency window for each access. Registered signalling adds one cycle of command delay versus unbuffered modules. Eight modules fill all available channels on supported ThinkMate platforms.
