Server ECC RDIMM Kit

This 16 GB DDR4 kit contains two 8 GB registered DIMMs built for servers and workstations that require error-correcting memory. The modules operate at 2666 MHz with CL19 latency and 1.2 V standard voltage. They are not compatible with desktop or laptop computers.

DDR4 Registered Interface

The registered design adds a clock cycle of buffering, which limits maximum speed compared with unbuffered modules but allows larger total capacities per channel. ECC detection and correction protects data integrity in multi-socket or mission-critical workloads. The 288-pin DDR4 form factor fits only DDR4 RDIMM slots.

Installation Notes

Align the module notch with the slot key and press firmly until both retention clips engage. Verify the system manual for correct channel population order; incorrect seating or mixing with unbuffered DIMMs will prevent boot.

Questions about this item

Should I choose this 16GB dual-channel kit or buy single 8GB modules instead?

This kit provides two matched 8GB modules totalling 16GB, enabling dual-channel operation on compatible server or workstation platforms.

What does the DDR4 2666 MHz rating mean for actual server workloads?

The modules run at 2666 MHz with CL19 latency, delivering PC4-21300 bandwidth for faster data access in multi-threaded server applications.

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

Registered ECC RDIMM design requires a server or workstation motherboard that supports registered DDR4 memory; it will not work in standard desktop or laptop systems.
