16 GB DDR3-1866 registered ECC module

This SK hynix HMT42GR7AFR4C-RD is a 16 GB DDR3 SDRAM DIMM rated for 1866 MT/s (PC3-14900) with CL13 latency and 1.50 V operation. It uses 240-pin registered ECC construction in a 2Rx4 organisation, built for server and workstation platforms that require registered memory with error correction.

Suited for servers needing registered ECC DDR3

The module fits systems designed for registered DDR3 DIMMs with ECC support at 1866 MT/s. Buyers whose platforms only accept unbuffered non-ECC memory, or that require a different DDR generation or a lower voltage, will need a different part.

Registered ECC DDR3 at 1866 MT/s decides fit

Registered ECC signalling at DDR3-1866 is the single specification that determines compatibility; the motherboard and processor must both support registered DDR3 DIMMs with error correction at this speed and voltage.

Questions about this item

What CAS latency does the module run at under sustained load?

The module operates at CL13 CAS latency during continuous operation.

How much power does each 16GB stick draw at 1.50V when running all day?

At the rated 1.50V the DDR3 registered DIMM draws only the power required for ECC and register logic, keeping heat output low in a 240-pin slot.

Which motherboard feature must already be present for this 2Rx4 registered ECC DDR3 memory to function?

The system must provide a DDR3 registered DIMM slot with ECC support; standard unbuffered consumer boards will not accept this module.
