16GB DDR4 2400 ECC RDIMM for Supermicro Servers

This 16GB DDR4 2400MHz registered DIMM carries Supermicro certification and uses Samsung chips. It targets administrators who need validated memory for supported Supermicro platforms. The module delivers ECC error correction and registered buffering for stable operation in multi-DIMM configurations.

Sustained Load Stability

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detection corrects single-bit errors that can accumulate under long-running workloads. The 1.20V standard voltage keeps power draw predictable across fully populated channels. CL17 latency at 2400MHz provides consistent timing for memory-bound server tasks.

Single-Rank 1Rx4 Organisation

The 1Rx4 rank structure determines how many modules the memory controller can address per channel. Buyers must confirm their platform's rank limits and qualified vendor list before ordering. This module will not suit systems that require dual-rank or x8 organisation.

Questions about this item

Does the 1.20V DDR4 2400 RDIMM run cooler than higher-voltage server memory during continuous operation?

This module operates at the standard DDR4 voltage of 1.20V, so its power draw and heat output match the baseline for DDR4 2400 registered DIMMs.

Must the motherboard support registered ECC DDR4 RDIMMs for this 288-pin module to function?

Yes, the system must accept DDR4 2400 registered ECC RDIMMs in a 288-pin slot; unbuffered or non-ECC boards will not work with this module.

Can this Samsung-based CL17 1Rx4 RDIMM populate empty slots alongside other DDR4 2400 registered ECC modules?

It can share channels with other DDR4 2400 registered ECC DIMMs, though the system will run all modules at the lowest common speed and timing.
