16GB DDR3 ECC RDIMM for servers

This 16GB DDR3 1866MHz ECC Registered DIMM is built for Supermicro platforms that require 2Rx4 registered memory. It suits administrators expanding capacity in compatible rackmount or tower servers running memory-intensive workloads.

Upgrade from lower-capacity or non-ECC DDR3 modules

Replacing smaller RDIMMs with this 16GB module increases total system memory while maintaining registered signal integrity and ECC protection. The jump is worth it when your current configuration hits capacity limits or lacks error correction for critical data.

Verify DDR3 RDIMM slot availability and 1.5V support

Confirm your motherboard accepts 240-pin DDR3 Registered DIMMs at 1.5V and supports 2Rx4 organisation. Check the vendor qualified-vendor list for the exact part number before ordering.

Questions about this item

Does the 240-pin RDIMM fit a standard DDR3 server DIMM slot?

Yes, the 240-pin RDIMM form factor is the standard DDR3 registered DIMM layout and will seat in any compatible DDR3 server memory slot.

Is there a specific order for populating the 2Rx4 registered modules on a Supermicro board?

Supermicro boards typically require registered DIMMs to be installed starting with the slot furthest from the CPU; check the motherboard manual for the exact population sequence.

Will the 1.5V DDR3 modules need any firmware updates or battery changes over time?

No firmware or battery maintenance is required for the memory modules themselves; they operate at the standard 1.5V DDR3 voltage for their service life.
