256GB DDR5 ECC kit for ThinkMate servers

This 256GB kit contains four 64GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for ThinkMate SuperServer 421GE-TNRT and 421GE-TNRT3 systems that require registered error-correcting memory. The modules operate at 1.1V and use a 2Rx4 organisation.

Registered 288-pin DIMMs without heat spreaders

Each module is a 288-pin DDR5 RDIMM without a heat spreader, relying on server chassis airflow for cooling. The registered buffer reduces electrical load on the memory controller, which is essential for stable operation in multi-DIMM server configurations. The kit ships as a matched set of four modules.

Verify DDR5 RDIMM support and slot population rules

Confirm that your ThinkMate platform accepts DDR5 registered ECC DIMMs and check the motherboard manual for the correct slot population order when installing four modules. Ensure the system firmware is current enough to support 64GB density modules at 4800 MT/s.

Questions about this item

Does the DDR5 4800 PC5-38400 interface limit the kit to 4800 MT/s on the ThinkMate 421GE-TNRT?

Yes, the modules are rated DDR5 4800 PC5-38400, so the maximum data rate on the ThinkMate 421GE-TNRT is 4800 MT/s.

Will the 288-pin 2Rx4 RDIMM modules fit the ThinkMate 421GE-TNRT3 DIMM slots?

The kit uses 288-pin DDR5 RDIMM modules with a 2Rx4 organisation that match the ThinkMate 421GE-TNRT3 memory slots.

Is there a specific slot population order when installing the four 64 GB sticks?

Populate the four 64 GB modules in the slot sequence shown in the ThinkMate server manual, typically starting with the slots closest to each CPU socket.
