128GB DDR5 4800 CL40 ECC registered server memory module for Thinkmate Supermicro SuperServer 521C-NR
This 128GB DDR5 4800 ECC RDIMM is a registered server memory module built for the Thinkmate Supermicro SuperServer 521C-NR. It delivers 128GB capacity in a single 288-pin module operating at 1.10V with CL40 latency. The 4Rx4 organisation and ECC support target enterprise workloads that require data integrity.
This module suits administrators expanding memory in the specified Thinkmate Supermicro SuperServer 521C-NR platform where registered ECC DDR5 is required. It is not for desktop or consumer boards that accept only unbuffered non-ECC memory. Buyers needing smaller capacities or different form factors should look at other options.
The 128GB density in one RDIMM determines whether the server can reach its target memory total within the available DIMM slots. Verify the platform's maximum supported capacity per slot and total population rules before purchase.

Registered ECC adds a buffer and error correction, allowing the 4Rx4 organisation to run reliably at 128 GB per module in the 521C-NR.
Yes, the 288-pin DDR5 RDIMM form factor matches the slots on the 521C-NR motherboard.
