Server ECC RDIMM for registered platforms

This 8 GB DDR3 module runs at 1866 MHz with PC3-14900 bandwidth and CL13 latency. It uses a registered design with ECC and a 1Rx4 organisation, operating at the standard 1.5 V. The 240-pin DIMM fits server and workstation boards that require registered memory.

Fits registered DDR3 slots.

The stick needs a motherboard that supports registered ECC DDR3; it will not work in consumer boards that only accept unbuffered modules. Using registered memory removes the electrical load of multiple ranks from the memory controller, allowing larger total capacities across populated slots.

Standard voltage keeps thermals modest

At 1.5 V the module draws typical DDR3 power without elevated heat, so standard server airflow is sufficient. Registered buffering adds negligible latency while the ECC logic corrects single-bit errors transparently, maintaining stability under sustained workloads.

Questions sur cet article

What is the CAS latency of this DDR3 1866MHz ECC RDIMM?

The module runs at CL13 latency, which is the timing figure listed for this 1866 MHz PC3-14900 registered DIMM.

How much power does the 1.50V registered DIMM draw under continuous server workloads?

It operates at the standard DDR3 voltage of 1.50V; registered buffering adds negligible extra draw compared with unbuffered modules of the same speed.

Which motherboard slot and chipset features are required for this 240-pin registered ECC module?

A DDR3 240-pin DIMM slot that supports registered ECC memory is required; consumer boards without registered support will not work.
