512GB DDR5 4800 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 4800 registered DIMMs built with ECC and a CL40 latency. It is designed for ThinkMate SuperServer 611C-TN4R and 621C-TN12R systems that require registered memory. The modules operate at 1.1V and use a 4Rx4 organisation.

Suited for ThinkMate 611C and 621C servers

This kit fits administrators expanding memory in the listed ThinkMate SuperServer models where registered ECC DDR5 is mandatory. It is not for workstations or desktops that accept only unbuffered non-ECC modules. Buyers needing lower capacities or different speeds should verify their platform requirements first.

Straightforward DIMM installation

The 288-pin DDR5 RDIMMs install into the server memory slots following the motherboard population guide. No heat spreaders are present so airflow clearance is standard. Common issues arise when mixing ranks or skipping the recommended slot order, which can prevent the system from posting.

Questions about this item

What server must I own for this 512GB DDR5 4800 kit to work?

The kit is validated for Thinkmate SuperServer 611C-TN4R and 621C-TN12R systems; it requires one of those platforms.

Can I keep my existing DDR5 4800 ECC RDIMM modules and add this 4Rx4 kit alongside them?

Mixing ranks is not recommended; the motherboard will run all channels at the slowest common timing, so replace the full set for best stability.

How do I confirm the 4Rx4 modules are running at CL40 after installation?

Enter the BIOS or use a tool like CPU-Z and verify the memory speed reads 4800 MT/s with CAS latency 40 and ECC active.
