256GB DDR4 ECC RDIMM kit

This 256GB kit provides two 128GB DDR4 3200 registered ECC modules for Thinkmate high-density servers. It targets administrators who need maximum capacity per DIMM slot in qualified platforms.

Tool-less DIMM installation

Modules seat in standard 288-pin DDR4 RDIMM sockets without tools; the registered buffer adds electrical load so the board must support 4Rx4 organisation. Mismatched rank or voltage prevents POST.

Steady 1.20V operation under load

Rated at 1.20V and CL22, the Samsung, Micron or Hynix ICs maintain specified timings during sustained server workloads. ECC correction keeps data integrity intact across long-running tasks.
