Capacity and Configuration

This kit delivers 1.5 TB of DDR5 memory across twelve 128 GB registered DIMMs. It is built for Thinkmate SuperServer 521C-NR systems that require high-density ECC memory for virtualization, database or compute workloads.

Compatibility Checks

Verify that your 521C-NR motherboard supports 4Rx4 registered modules at 4800 MT/s and 1.1 V. Confirm the BIOS is current enough to initialise twelve DIMMs and that the CPU memory controller can address the full 1.5 TB capacity.

Ideal Use and Limits

Suited for administrators expanding a qualified Thinkmate 521C-NR to its maximum supported memory. Not intended for desktop boards, consumer workstations or any platform that does not accept 288-pin DDR5 RDIMMs with ECC and registered buffering.

Questions about this item

What is included in the kit and do I need to buy anything else to install it?

The kit contains twelve 128 GB DDR5 4800 ECC RDIMM modules for a total of 1.5 TB. No additional memory parts are required; install the modules directly into the server's 288-pin DDR5 slots.

How do I decide between the available versions or capacities for this ThinkMate 521C-NR kit?

This part number MR38400-744K12 is a single 1.5 TB configuration (12 x 128 GB) validated for the ThinkMate 521C-NR. Choose it when the platform needs the full 1.5 TB capacity at DDR5 4800 CL40.

What does the DDR5 4800 CL40 rating mean once the memory is running in the server?

The modules operate at 4800 MT/s with a CAS latency of 40 cycles at 1.1 V, delivering PC5-38400 bandwidth per module. The registered 4Rx4 ECC design adds error correction and signal buffering for stable operation under sustained server workloads.
