128GB DDR5 4800 ECC RDIMM kit

This 128GB kit contains eight 16GB DDR5 4800 modules built for ThinkMate TWX-XS8 tower servers. ECC and registered operation protect data integrity in mission-critical workloads. Each module runs at 1.1V with CL40 latency and a single-rank 1Rx8 organisation. The 288-pin RDIMM form factor fits the qualified platforms directly.

Tool-free DIMM installation

Modules slot into the server's 288-pin DDR5 sockets without extra tools or cables. Registered buffering adds electrical load, so population rules in the system manual must be followed exactly. Mixing ranks or speeds can prevent the system from posting. A clean, static-free workspace and a quick reseat usually resolve any detection issues.

Suited for ThinkMate TWX-XS8 upgrades

Ideal for administrators expanding memory capacity in the listed ThinkMate tower servers. Not intended for consumer desktops, laptops or non-qualified workstations that require unbuffered UDIMMs or different voltage profiles. Buyers needing higher frequencies, lower latencies or larger single-module densities should evaluate other qualified kits.
