Server Memory Upgrade

This 32 GB DDR4 module is built for Xeon Scalable or EPYC servers that require registered ECC memory. It plugs into a 288-pin slot and runs at the rated speed without manual tuning.

Registered ECC Architecture

The 2Rx8 registered design offloads the memory controller so every slot can be fully populated at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots.

Thermals Power and Noise

Operating at 1.2 V the module draws minimal power and produces no audible noise because it has no moving parts. Standard server airflow keeps temperatures within specification during continuous operation.

Questions about this item

Will the 3200 MT/s rating actually run at that speed in my Xeon Scalable server?

Yes — when installed in a supported Xeon Scalable or EPYC platform the module operates at DDR4 3200 (PC4-25600) with CL22 timings at 1.2 V, delivering the full rated data rate.

What does the registered ECC design do for a fully populated 288-pin channel?

The registered buffer reduces electrical load on the memory controller so every slot can be filled at full capacity, while ECC detects and corrects single-bit errors on the fly to prevent silent data corruption.

Does the 288-pin RDIMM fit standard server DIMM slots without extra hardware?

Yes — it uses the standard 288-pin DDR4 RDIMM form factor and mounts directly into any compatible server DIMM socket; no adapters or special brackets are required.
