  • Our take on the DDR4 2666MHz PC4-21300 RDIMM

    This is a single DDR4-2666 ECC Registered (RDIMM) server memory module, PC4-21300, 288-pin, running at 1.2V. It is built for registered-memory platforms such as the ASRock Rack ROMED8-2T and comparable enterprise servers and workstations, and NEMIX says it is compatibility-tested for drop-in use. Registered ECC modules like this are the standard choice for AMD EPYC and Intel Xeon server boards that require buffered memory; they will not work in consumer desktop boards that take unbuffered DIMMs. Buyers get a lifetime warranty from a US-based server memory specialist, which is the main thing setting it apart from generic no-name RDIMMs.

    Questions and answers

    Will this work in a regular desktop PC?
    No. It is Registered (buffered) ECC memory, which only works in server and workstation boards that support RDIMMs, such as the ASRock Rack ROMED8-2T. Consumer desktop boards take unbuffered DIMMs.
    Is it compatible with the ASRock Rack ROMED8-2T?
    NEMIX lists this module as compatibility-tested for that board. The board requires DDR4 ECC Registered memory, which this is.
    What speed and voltage does it run at?
    It is DDR4-2666, PC4-21300, at 1.2V. That is the JEDEC standard for this speed bin.
    Can I mix it with other RDIMMs?
    Mixing brands and part numbers in a server can cause instability. For best results, populate channels with identical modules.
    What is covered by the warranty?
    NEMIX backs the module with a lifetime warranty.
    Is it one module or a kit?
    It is a single RDIMM module, not a matched multi-module kit.
    Where is the DDR4 2666MHz PC4-21300 RDIMM cheapest?
    At NEMIX RAM, for $80.99, as of our latest check.
    Where can I buy the DDR4 2666MHz PC4-21300 RDIMM?
    2 stores we checked sell it, including NEMIX RAM, Amazon.
