16GB DDR4 ECC RDIMM for Supermicro servers

This 16GB DDR4 3200MHz registered DIMM is built for Supermicro motherboards including the H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN and H11SSL-C. It delivers error-correcting, registered memory for workstation and server platforms that require ECC RDIMM modules. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained operation with ECC protection

The module runs at 1.2V with CL22 latency and a 2Rx8 organisation, providing consistent throughput under continuous server workloads. Error-correcting code detects and corrects single-bit errors in real time, helping to maintain data integrity during long compute sessions without the variability seen in non-ECC alternatives.

288-pin registered build without heat spreader

A bare 288-pin PCB fits directly into standard DDR4 RDIMM slots on the listed Supermicro boards, leaving clearance for dense multi-DIMM populations. The registered buffer reduces electrical load on the memory controller, supporting stable operation across fully populated channels day after day.

Questions about this item

How much power does the 1.2 V DDR4 3200 module draw under continuous server load?

The module operates at 1.2 V DDR4 standard voltage; exact power draw varies with workload and motherboard power management.

Which motherboard slots and chipset are required for this 288-pin ECC RDIMM to function?

It requires a Supermicro H11DSi, H11DSi-NT, H11DST-B, H11DSU-iN or H11SSL-C motherboard with DDR4 RDIMM slots and registered ECC support.

Can this CL22 registered DIMM run alongside older unbuffered ECC modules in the same system?

No, registered and unbuffered ECC memory cannot be mixed; all installed DIMMs must be registered for the system to operate.
