ThinkMate SuperServer 521C-NR DDR5 kit

This 128 GB kit contains four 32 GB DDR5 4800 registered ECC RDIMMs built for the ThinkMate SuperServer 521C-NR. The modules run at 1.1 V with CL40 latency and use a 288-pin 1Rx4 layout. They are intended for server and workstation workloads that require error-correcting memory.

Compatibility check before ordering

Confirm that your system is the ThinkMate SuperServer 521C-NR and that its memory slots accept DDR5 288-pin RDIMMs. Verify the platform supports registered ECC modules at 4800 MT/s and 1.1 V. Ensure enough free slots exist for the four-module population and that the BIOS is current for DDR5 operation.

Suited for ThinkMate DDR5 servers

This kit suits administrators upgrading a ThinkMate SuperServer 521C-NR to 128 GB of registered ECC DDR5. It is not for desktop PCs, laptops or consumer motherboards that require unbuffered non-ECC memory. Buyers who need a different capacity, speed or form factor should look at other memory kits.

Questions about this item

Does the kit include the four 32 GB modules only, or are any brackets or cables supplied?

The package contains the four 32 GB DDR5 4800 CL40 1.10 V ECC RDIMM modules and nothing else.

Should I choose this 128 GB kit or a smaller capacity for the SuperServer 521C-NR?

Select this 128 GB kit when the workload needs the full 4 x 32 GB configuration; a smaller kit would leave memory slots empty and reduce total capacity.

What does the 4800 MT/s rating mean once the kit is installed in the SuperServer 521C-NR?

The modules will run at DDR5 4800 with CL40 latency at 1.10 V, delivering the rated PC5 38400 bandwidth for registered ECC workloads.
