  • Our take on the 128GB Kit (4x32GB) 4Rx4 DDR4 2133MHz (PC4-17000) LRDIMM

    This is a 128GB memory kit made of four 32GB DDR4 LRDIMMs running at 2133MHz (PC4-17000). Each module is quad-rank (4Rx4), which is the load-reduced design servers use to reach high capacity per channel. It is aimed at server and workstation builds, and the kit is listed as an upgrade for the ASRock Rack ROMED8-2T. Against registered RDIMMs, LRDIMMs carry more capacity per module but cost more and add a little latency, so buy it only if your board and CPU support LRDIMMs and you need the density.

    Pros
    • 128GB total from four modules leaves slots free
    • Quad-rank LRDIMM design for high capacity per channel
    • Standard 2133MHz DDR4 speed with broad platform support
    • Matches a listed server board, the ROMED8-2T
    Cons
    • LRDIMMs need board and CPU support; many desktops reject them
    • 2133MHz is the slowest DDR4 bin
    • Quad-rank modules can force lower speeds with many DIMMs populated
    • No ECC confirmation or heatsinks stated

    Questions and answers

    Will this work in a regular desktop PC?
    Usually not. LRDIMMs need a motherboard and CPU that explicitly support load-reduced memory, which is mostly server and workstation platforms. Check your board's qualified memory list before buying.
    Is this the same as registered ECC RDIMM memory?
    No. LRDIMMs use a buffer chip to reduce electrical load and allow higher capacity per module. They are not interchangeable with RDIMMs or unbuffered DIMMs on most boards.
    Why is 2133MHz used here?
    It is the standard DDR4 speed for many server platforms, and high-capacity quad-rank modules often run at JEDEC speeds like this. Faster kits exist, but the board and CPU must support them.
    Do I need all four modules installed?
    The kit is matched as a four-module set. Populating all four gives 128GB and the intended per-channel balance; using fewer modules lowers total capacity.
    Does it fit the ASRock Rack ROMED8-2T?
    It is listed as an upgrade for that board. Confirm the board's current memory support and BIOS level, since qualified lists can change.
    Where is the 128GB Kit (4x32GB) 4Rx4 DDR4 2133MHz (PC4-17000) LRDIMM cheapest?
    At Amazon, for $740.70, as of our latest check.
    Where can I buy the 128GB Kit (4x32GB) 4Rx4 DDR4 2133MHz (PC4-17000) LRDIMM?
    2 stores we checked sell it, including Amazon, A-Tech Memory.
