A-Tech 16GB DDR3L ECC RDIMM for Servers

This 16GB registered DIMM runs at DDR3L 1866MHz with a CL13 latency and 1.35V operation. It is built as a direct replacement for Hynix HMT42GR7AFRAC-RD, HMT42GR7BFR4A-RD and HMT42GR7DFR41-RD modules. The 2Rx4 organisation and ECC support target server and workstation platforms that require registered memory.

Installing the 240-pin DIMM into a compatible slot

Align the notch on the module with the key in the DDR3 slot and press firmly until the retention clips lock. Registered DIMMs must be supported by the motherboard chipset; unbuffered consumer boards will not recognise the module. The 1.35V low-voltage spec also requires a platform that can supply DDR3L levels.

Check your system manual for DDR3L registered

Verify that the server or workstation accepts 16GB 2Rx4 registered modules at 1866MHz and 1.35V before ordering. Some platforms limit maximum capacity per slot or require specific population rules for multi-rank DIMMs. This module is not compatible with systems that only support unbuffered non-ECC memory.

Questions about this item

How do I confirm the module runs at 1866 MHz CL13 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report DDR3L-1866 with CAS latency 13 and 1.35 V operation.

What comes in the box and do I need anything else?

One 16 GB DDR3L 240-pin ECC RDIMM is included; no extra cables or brackets are required, just an available registered DIMM slot.

Which Hynix part number does this 16 GB DDR3L 1866 MHz module replace?

It is a compatible replacement for Hynix HMT42GR7AFRAC-RD, HMT42GR7BFR4A-RD, and HMT42GR7DFR41-RD.
