Server ECC RDIMM upgrade

This 16GB DDR4 registered DIMM is built for Supermicro X10DAX, X10DDW-i, X10DDW-iN, X10DGO and X10DGO-T motherboards. It targets administrators who need error-correcting memory in workstations, servers or NAS appliances. The module is not compatible with standard desktop platforms and must not be mixed with unbuffered DIMMs.

Registered ECC at DDR4 2400

The single specification that decides fit is the registered ECC design running at PC4-19200 CL17 on a 288-pin interface. Only systems that explicitly support registered error-correcting modules at this speed and latency will accept the upgrade.

Low-voltage thermal profile

Operating at 1.2V without a heat spreader, the module draws minimal power and runs quietly in normal server chassis airflow. Passive cooling is sufficient for typical workloads on the listed Supermicro boards.

Questions about this item

How does the 2400MHz speed translate once the module is installed in a Supermicro X10 motherboard?

The module runs at DDR4 2400 (PC4-19200) with CL17 latency at 1.2V, delivering the rated throughput on the supported Supermicro X10DAX, X10DDW-i, X10DDW-iN, X10DGO and X10DGO-T boards.

What does the ECC Registered interface cap in practice?

ECC Registered operation provides error correction and signal buffering for server and workstation workloads; it cannot be mixed with unbuffered memory and is not compatible with standard desktop platforms.

Will the 288-pin RDIMM fit in the DIMM slots of my Supermicro X10DGO-T?

Yes, the 288-pin DDR4 RDIMM form factor matches the memory slots on the listed Supermicro X10 series motherboards and requires no heat spreader clearance.
