4GB DDR3 1866 ECC RDIMM

This 4GB registered ECC module is built for server and workstation platforms that require DDR3 1866 registered memory. It suits administrators upgrading HP systems using part number 733484-001 or similar validated configurations. The single-rank 1Rx4 organisation keeps electrical loading low on populated channels.

Capacity and headroom

At 4GB per module the stick adds modest capacity for memory-bound services such as virtualization hosts or database buffers. CL13 latency at 1866 MT/s delivers predictable throughput for typical enterprise workloads. The limit appears when applications demand more than a few gigabytes per channel or require higher frequencies than DDR3 1866 provides.

Build integration

The 240-pin DIMM installs in standard DDR3 registered slots and operates at the standard 1.5V. Registered signalling reduces load on the memory controller, freeing electrical headroom for additional modules on the same channel. Systems must support ECC RDIMM operation; consumer boards without registered-buffer support cannot use this module.

Questions about this item

Will this DDR3 1866 RDIMM run at 1866 MHz alongside older DDR3 modules rated at lower speeds?

The module operates at DDR3 1866 (PC3-14900) with CL13 latency at 1.5V. When mixed with slower DDR3 DIMMs, the system typically clocks all memory down to the lowest common speed and loosest timings.

How can I confirm the ECC registered function is active after installing this 1Rx4 module?

Enter the server BIOS or UEFI and check the memory configuration screen; it should report ECC enabled and show the module as registered (RDIMM) with 1Rx4 organization and the correct 4GB capacity.

Does the box contain only the 240-pin DIMM or are any cables or brackets included?

The package includes the single 4GB DDR3 1866 ECC RDIMM (240-pin DIMM) only. No cables, brackets, heatsinks or additional accessories are supplied.
