Targeted Server Upgrade

This 16 GB kit contains two 8 GB DDR3 1333 CL9 registered ECC modules built for Supermicro SuperServer 1026, 2026 and 6016 series systems. It is designed for administrators who need to expand memory capacity in compatible rackmount or tower servers running DDR3 platforms.

Registered ECC Functionality

The registered buffer and error-correcting code work together to stabilise heavy multi-module configurations and protect data integrity in continuous workloads. These modules cannot be used in standard desktop boards and must not be mixed with unbuffered memory.

Capacity and Limits

The kit delivers 16 GB total across two 240-pin DIMMs, providing headroom for virtualisation hosts, database caches or multi-user file services. Servers requiring larger memory footprints or higher DDR3 speeds will need additional modules or a different platform.

Questions about this item

Will the 2Rx4 ECC registered DIMMs need any firmware updates or battery replacements over time?

The modules have no onboard firmware or battery; they operate as standard JEDEC DDR3 1333 CL9 parts and require no scheduled maintenance.

What thermal limit appears first when the kit runs continuously in a fully populated Supermicro SuperServer 1026GT chassis?

The 1.5 V DDR3 parts rely on the server's own airflow; no heat spreader is fitted, so case cooling capacity becomes the limiting factor before the memory itself throttles.

How much extra power draw and fan noise should I expect from the 16 GB kit under 24/7 load?

Each 8 GB RDIMM draws roughly 3–4 W at 1.5 V, adding minimal heat; the existing system fans typically handle the load without audible speed increase.
