Targeted Server Upgrade

This kit provides 32 GB of DDR3 ECC registered memory in a matched pair of 16 GB modules. It is built for Supermicro SuperWorkstation 7036A and 7046A systems that require registered DIMMs.

Registered ECC Difference

The modules operate at 1333 MHz with CL9 latency and 1.5 V. Registered buffering and ECC correction maintain data integrity in multi-socket workstations and prevent mixing with unbuffered desktop memory.

Workstation And Server Builders

Suited for administrators extending the life of compatible Supermicro platforms or assembling replacement nodes. Not for standard desktop PCs, laptops or any system that accepts only unbuffered non-ECC DIMMs.

Questions about this item

Will the 240-pin DDR3 RDIMMs need any periodic replacement or maintenance after installation?

No, DDR3 ECC registered modules have no moving parts or serviceable components; once seated they run for the life of the system unless a rare defect appears.

What limit appears first when the 32 GB kit runs at 1333 MHz under continuous load?

The memory controller’s maximum supported capacity and rank population rules for the Supermicro 7036A or 7046A workstation will cap usable slots before bandwidth saturates.

How much heat and power do the 1.5 V 2Rx4 modules produce during all-day operation?

Each 16 GB stick draws standard DDR3 1.5 V power and emits typical registered-DIMM heat; no spreader is fitted, so case airflow handles cooling.
