8GB DDR3 1866 ECC RDIMM server module

This 8GB DDR3 1866 MHz registered DIMM delivers error-correcting memory for server and workstation platforms. It operates at the standard 1.50V DDR3 voltage with a CL13 latency and a single 1Rx4 rank using major-brand chips. The 240-pin form factor fits compatible DDR3 slots.

Suits systems needing registered ECC DDR3 at 1866

Administrators replacing Hynix HMT41GR7AFR4C-RD, HMT41GR7BFR4C-RD or HMT41GR7DFR4C-RD modules can use this as a direct equivalent. Builders requiring unbuffered UDIMMs, higher speeds, different voltages or larger single-module capacities should select other memory types.

1Rx4 rank configuration with CL13 latency

The module uses a single-rank 1Rx4 organisation and runs at CL13, which determines how it pairs with existing memory and how the memory controller schedules commands. Verify that your platform supports this rank structure and timing before installation.

Questions about this item

Which capacity and configuration suits a single-slot upgrade?

This module is an 8GB 1Rx4 DDR3 1866 registered DIMM, so one stick adds 8GB in a single 240-pin slot.

What does the DDR3 1866 rating deliver in a live server?

The module runs at 1866 MT/s with CL13 latency at the standard 1.50 V DDR3 voltage.

How does the registered ECC interface affect usable speed?

The registered buffer adds one cycle of address stability, and ECC corrects single-bit errors, both operating within the DDR3 1866 specification.
