1TB DDR5 4800 ECC RDIMM kit

This 1TB memory kit contains eight 128GB registered DIMMs built for the ThinkMate GPX-XH8-22S4-8GPU GPU-optimised server. Each module runs at DDR5 4800 with CL40 latency and 1.1V operation. ECC and registered buffering protect data integrity in mission-critical workloads.

Eight-module population fills every slot

The kit supplies a full 1TB across all eight DIMM positions so the server can run at maximum configured capacity without mixing module sizes. 4Rx4 organisation and Samsung, Micron or Hynix chips deliver the density required for GPU-accelerated compute tasks.

Verify eight-slot support

Confirm the motherboard provides eight DDR5 RDIMM slots and accepts 4Rx4 registered modules at 1.1V. Systems limited to fewer slots or unbuffered memory cannot use this kit. Check the server manual for population rules before ordering.

Questions about this item

Will the 1.1 V DDR5 modules need active cooling in a ThinkMate GPX-XH8-22S4-8GPU running continuously?

These 288-pin RDIMMs operate at 1.10 V without a heat spreader; the registered design reduces electrical load on the memory controller, keeping thermal output low and silent during sustained workloads.

What is the first limit reached when all eight 128 GB sticks run at DDR5 4800 CL40 under heavy load?

The CAS latency of CL40 at 4800 MT/s sets the timing ceiling; bandwidth scales with the eight-channel layout of the compatible ThinkMate server.

Does the 4Rx4 organisation change replacement planning compared to lower-rank modules?

Each 128 GB module uses a 4Rx4 configuration; if a single rank fails the entire stick must be swapped, so keep one spare 128 GB RDIMM on hand.
