16GB DDR3 1866MHz ECC RDIMM

This 16GB registered DIMM runs at DDR3 1866MHz with CL13 latency and 1.5V operation. It is built for servers and workstations that require error-correcting memory. The module uses a 2Rx4 organization and major-brand chips for stable performance. Buyers needing non-ECC or unbuffered memory for desktop platforms should look elsewhere.

Registered ECC with 2Rx4 organization

The single decisive specification is the registered ECC RDIMM design with 2Rx4 rank configuration. This combination ensures compatibility only with motherboards that explicitly support registered error-correcting modules. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use this module. Verify your platform documentation before purchasing to confirm registered ECC support.

Standard 1.5V DDR3 thermals

Operating at the standard DDR3 voltage of 1.5V, the module draws typical power for its class without elevated heat output. Registered buffering adds minimal electrical load while improving signal integrity at 1866MHz. Passive cooling in a server chassis with adequate airflow is sufficient for normal workloads. No active cooling or special thermal management is required for this memory type.

Questions about this item

What does the DDR3 1866 (PC3-14900) speed rating mean for actual throughput in a server?

The DDR3 1866 rating indicates a data rate of 1866 MT/s; real-world throughput depends on the memory controller, channel population and BIOS settings of the host system.

How does the registered ECC RDIMM interface affect compatibility and maximum capacity?

Registered ECC RDIMMs use a register to reduce electrical load, allowing larger memory populations per channel, but they require a motherboard that supports registered DIMMs and ECC functionality.

What physical slot and clearance does the 240-pin DIMM need to install?

The module uses a standard 240-pin DDR3 DIMM form factor; it fits any DDR3 RDIMM slot with sufficient vertical clearance for the module height.
