  • Our take on the 512GB Kit (8x64GB) 2Rx4 DDR4 2933MHz (PC4-23400) RDIMM

    This is a 512GB server memory kit made of eight 64GB DDR4-2933 (PC4-23400) registered DIMMs in 2Rx4 organization. Registered ECC memory is built for servers and workstation boards that take RDIMMs, not for consumer desktops, which use unbuffered DIMMs. The kit is aimed at the ASRock Rack ROMED8-2T and similar EPYC server boards that need high capacity across eight channels. Against smaller 16GB or 32GB RDIMMs, it trades a much higher capacity ceiling for a higher cost per gigabyte and stricter platform requirements.

    Pros
    • 512GB total in eight matched 64GB modules
    • DDR4-2933 speed suits EPYC 7002/7003 platforms
    • Registered ECC for server-grade reliability
    • 2Rx4 organization is widely supported on server boards
    • Fills all eight channels for maximum bandwidth
    Cons
    • RDIMMs will not work in consumer desktop boards
    • High cost per gigabyte versus smaller modules
    • Only useful on platforms that accept registered ECC DDR4
    • Mixing with existing unmatched DIMMs can cause training issues

    About the 512GB Kit (8x64GB) 2Rx4 DDR4 2933MHz (PC4-23400) RDIMM

    This is a 512GB memory kit made up of eight 64GB DDR4 RDIMM modules. The modules run at 2933MHz (PC4-23400) and use ECC registered memory.

    The modules are dual rank (2Rx4) with a 288-pin form factor and operate at 1.2V. The kit is designed as an upgrade for the ASRock Rack ROMED8-2T and is compatible with servers and workstations.

    Questions and answers

    Will this kit work in a regular desktop PC?
    No. These are registered DIMMs, and consumer desktop boards use unbuffered DIMMs. It needs a server or workstation board that explicitly supports DDR4 RDIMMs.
    Is it compatible with the ASRock Rack ROMED8-2T?
    The kit is specified for that board, which supports eight-channel DDR4 RDIMMs. Confirm the board's current memory qualified vendor list before buying.
    What does 2Rx4 mean?
    It means each module is dual-rank with x4 organization. Server boards list which rank and organization combinations they support, so check that before installing.
    Can I add this to memory I already have?
    Mixing capacities, speeds or ranks can force lower speeds or fail memory training. For best results, populate all eight slots with this matched kit.
    Does it run at 2933MHz in every system?
    Speed depends on the CPU and board. EPYC platforms that support DDR4-2933 can run it at full speed; older or limited platforms may run it slower.
    Is ECC active with this memory?
    Yes, registered DIMMs include ECC, but the board and CPU must support registered ECC for it to be enabled.
    Where is the 512GB Kit (8x64GB) 2Rx4 DDR4 2933MHz (PC4-23400) RDIMM cheapest?
    At Amazon, for $4,616.72, as of our latest check.
    Where can I buy the 512GB Kit (8x64GB) 2Rx4 DDR4 2933MHz (PC4-23400) RDIMM?
