DDR3 1866 ECC RDIMM 16GB Server Module

This A-Tech module delivers 16GB of DDR3 1866 registered ECC memory in a single 240-pin DIMM. It runs at 1.50V with CL13 latency and uses a 2Rx4 organisation built on major-brand chips. The specification matches Hynix part numbers HMT42GR7AFR4C-RD, HMT42GR7BFR4C-RD, HMT42GR7DFR4C-RD and HMT82GV7AMR4C-RD for direct replacement in compatible servers and workstations.

Suited for DDR3 Registered ECC Platforms Only

Administrators upgrading or repairing servers that require DDR3 1866 registered ECC DIMMs will find the correct form factor, voltage and error-correction here. Systems that accept only unbuffered non-ECC modules, or platforms that have moved to later DDR generations, cannot use this module and need a different memory type.

Registered ECC With 2Rx4 Organisation Is Mandatory

The motherboard and memory controller must support registered ECC DIMMs with a 2Rx4 rank configuration at DDR3 1866 speed. If the platform requires unbuffered memory, non-ECC operation, a different rank layout or another DDR generation, this module will not function.

Questions about this item

Does this 16GB DDR3 1866 module need a 240-pin DIMM slot?

Yes, the module uses the standard DDR3 DIMM form factor with 240 pins and requires a matching registered DIMM slot on the server or workstation motherboard.

What is the correct way to seat this registered ECC RDIMM, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click, and verify the system recognises the full 16GB at 1866 MHz; the common miss is not pressing hard enough to engage both clips.

Will this 1.5V DDR3 1866 RDIMM need any firmware updates or component swaps over its service life?

No firmware updates are required for the memory itself; the module is a solid-state component with no moving parts, so it only needs replacement if a memory test reports errors or the system fails to POST.
