32GB DDR5 4800 ECC RDIMM for SuperMicro

This 32GB DDR5 4800 ECC registered DIMM is built for SuperMicro CloudDC SuperServer platforms. It runs at 1.10V with CL40 latency and a 1Rx4 organisation. The module uses major OEM DRAM and is stress tested for stability in enterprise environments.

Suits SuperMicro SYS-621C-TN12R SYS-611C-TN4R

This memory fits the listed SuperMicro CloudDC SuperServer models requiring registered ECC DDR5. Builders needing unbuffered UDIMMs or non-ECC modules for consumer motherboards should look elsewhere. Systems that do not support registered DDR5 cannot use this part.

Registered ECC RDIMM with 1Rx4 organisation

The single specification that decides fit is the registered ECC RDIMM format with 1Rx4 rank structure. Only motherboards qualified for registered DDR5 ECC at 4800MT/s will accept this module. Verify your platform documentation before purchase.

Questions about this item

Will the 1.10V registered DIMM need any firmware updates or component swaps during its service life?

No firmware updates or component swaps are required; the module is a standard JEDEC DDR5 RDIMM that operates at its rated 1.10V for the duration of its installed life.

What limit appears first when the CL40 4800 MT/s module runs sustained workloads in a 1Rx4 configuration?

The memory controller’s maximum supported bandwidth at DDR5 4800 is the first bottleneck; the single-rank 1Rx4 layout cannot exceed the controller’s peak throughput under continuous load.

How much heat and power does a 32GB 1.10V registered DIMM generate during all-day operation?

At 1.10V the module draws minimal power and produces low heat; the registered buffer adds negligible thermal load, so standard server airflow keeps temperatures well within spec.
