Server ECC RDIMM Upgrade

This 16GB DDR3L 1600 CL11 registered DIMM adds ECC protected capacity to compatible Supermicro SuperServer systems. It operates at 1.35V with a 2Rx4 organisation and fits 240-pin DDR3 slots. The module is designed for workstation and server platforms that require registered memory with error correction.

Workstation and Server Builders Only

This memory suits administrators expanding Supermicro 2027PR, 2027R, 2027TR, 2028UT or 4027GR series servers. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. Buyers needing consumer DDR3 or non-ECC SODIMMs should look elsewhere.

Single Module for Registered Slots

Install one 16GB stick into an available 240-pin registered DIMM slot on a supported Supermicro motherboard. The 1.35V DDR3L voltage reduces power draw compared to standard DDR3. No heat spreader is fitted, so airflow across the module is required.

Questions about this item

Do I need a Supermicro SuperServer from the 2027, 2028 or 4027 series for this module to work?

Yes, this 240-pin DDR3L ECC RDIMM is validated for Supermicro SuperServer 2027PR, 2027R, 2027TR, 2028UT and 4027GR series. It will not work in standard desktop boards.

Can I add this 16GB 1.35V registered stick alongside existing 1.5V unbuffered DDR3 DIMMs?

No. The module is registered ECC DDR3L at 1.35V and must not be mixed with unbuffered memory or different voltage DIMMs. All slots should use identical registered modules.

How can I verify the module is running at PC3L-12800 CL11 after installation?

Enter the server BIOS or use a tool such as dmidecode to confirm the detected speed shows 1600 MT/s, voltage 1.35V, CAS latency 11 and ECC registered status.
