32GB DDR4 ECC RDIMM for Supermicro servers

This 32GB DDR4 2400MHz registered DIMM carries Supermicro certification for validated compatibility. ECC error correction and dual-rank 2Rx4 organisation protect data integrity in continuous workloads. The module targets administrators expanding memory in qualified Supermicro platforms.

Standard voltage and registered buffering

Operation at 1.20V follows the DDR4 baseline, limiting power draw per module. Registered signalling reduces electrical load on the memory controller, aiding stability in dense configurations. No active cooling is required under normal server airflow.

288-pin RDIMM form factor

The 288-pin registered layout fits only DDR4 RDIMM slots; it will not seat in UDIMM or LRDIMM sockets. Builders needing unbuffered ECC or load-reduced modules must select a different part. Verify the system memory list before installation.

Questions about this item

How do I install this 288-pin RDIMM and what step is commonly missed?

Align the notch on the module with the slot key, press firmly until both side clips click, and ensure the registered buffer engages — the step often missed is verifying the motherboard supports registered ECC DDR4 before installation.

What maintenance or replacement will this 32GB DDR4 module need over time?

No routine maintenance is required; the module is validated for continuous server operation. Replacement is only necessary if memory errors appear or capacity needs exceed 32GB per slot.

What limit appears first during sustained workloads on this CL17 1.20V kit?

The DDR4 2400 bandwidth ceiling of 19200 MB/s per module is reached before thermal or voltage limits under sustained registered ECC workloads.
