  • Our take on the 64GB Kit (2x32GB) 2Rx4 DDR4 2133MHz (PC4-17000) RDIMM

    This is a 64GB registered DDR4 memory kit: two 32GB 2Rx4 RDIMMs running at 2133MHz (PC4-17000). Registered ECC modules of this kind are built for servers and workstation boards, not consumer desktops, and the kit is listed as an upgrade for the ASRock Rack ROMED8-2T. Against faster DDR4-2666 or 2933 RDIMMs it trades bandwidth for stability and broad board compatibility, which is what most buyers of this class want. Choose it if your board and CPU support registered DDR4 at this speed; skip it for any desktop that takes unbuffered DIMMs.

    Pros
    • Two 32GB modules give 64GB total in a single kit
    • Registered ECC design for server and workstation boards
    • 2Rx4 organization suits high-capacity slot configurations
    • 2133MHz is a conservative, widely supported DDR4 speed
    • Matched pair reduces the risk of mixing mismatched sticks
    Cons
    • Registered DIMMs will not work in consumer desktop boards
    • 2133MHz is slower than common 2666MHz and 2933MHz server DDR4
    • 2Rx4 modules can be restricted on some platforms and slot counts
    • No heatsinks or RGB, as expected for server memory
    • Buyers must confirm board and CPU support before ordering

    Questions and answers

    Will this work in a regular desktop PC?
    No. These are registered DIMMs, and consumer desktop boards take unbuffered DIMMs. Use it only in a server or workstation board that explicitly supports registered DDR4.
    Is it compatible with the ASRock Rack ROMED8-2T?
    It is listed as an upgrade kit for that board. Confirm the installed CPU and current firmware support 32GB 2Rx4 RDIMMs at 2133MHz before buying.
    Can I mix it with my existing DDR4 memory?
    Only if the existing modules match in type, rank and speed. Mixing registered and unbuffered memory, or different ranks, usually prevents the system from booting or running at full speed.
    Is 2133MHz fast enough?
    For memory-bound server workloads, faster 2666MHz or 2933MHz RDIMMs give more bandwidth. For capacity-focused builds, 2133MHz is a safe, broadly compatible choice.
    What is in the kit?
    Two 32GB DDR4 RDIMMs, 2Rx4, 2133MHz (PC4-17000), for 64GB total.
    Do I need ECC support enabled?
    Yes. The board and CPU must support registered ECC memory; this kit is not intended for non-ECC platforms.
    Where is the 64GB Kit (2x32GB) 2Rx4 DDR4 2133MHz (PC4-17000) RDIMM cheapest?
    At Amazon, for $455.95, as of our latest check.
    Where can I buy the 64GB Kit (2x32GB) 2Rx4 DDR4 2133MHz (PC4-17000) RDIMM?
    2 stores we checked sell it, including Amazon, A-Tech Memory.
