Server memory upgrade

This kit provides 32GB of DDR3 ECC registered memory in a matched pair of 16GB modules. It is built for Supermicro SuperServer 5086B, 8026B and 8046B systems that require registered DIMMs. The modules will not work in standard desktop computers or alongside unbuffered memory.

Thermals and power

Each module runs at the standard DDR3 voltage of 1.5V without a heat spreader. Registered buffering reduces electrical load on the server memory controller during normal operation. The CL9 latency at 1333MHz delivers stable throughput for typical server workloads.

Registered ECC constraint

The 2Rx4 registered ECC design is the single factor that determines compatibility; this memory only functions in platforms that explicitly support registered DIMMs. Buyers needing unbuffered or non-ECC modules for workstations or desktops must choose a different product.

Questions about this item

How do I install the 240-pin DDR3 1333 RDIMM kit in a Supermicro 5086B, 8026B or 8046B server?

Power down, open the chassis, align each 16 GB module’s notch with the DIMM slot key, press firmly until the retention clips click, then populate slots in the order the server manual specifies for registered memory.

What maintenance or replacement will the ECC registered RDIMM kit need over its service life?

No routine maintenance is required; the modules carry a limited lifetime warranty and an advanced replacement programme, so a failed stick is swapped rather than repaired.

What is the first limit reached when the 2Rx4 1.5 V DDR3 1333 kit runs sustained workloads?

The memory controller’s maximum supported capacity and rank-per-channel limit will be reached before the modules hit thermal or voltage thresholds.
