Buckle up! Apacer launches seat belt for RAM sticks — protection for DIMMs from vibration damage

Apacer has announced a new solution for DIMM modules that won’t stay in place: rugged retention straps for RAM that keep DIMMs secure from even the highest-intensity vibrations.

Marketed towards “Edge AI” use cases, which include long-distance transport or vibration-sensitive implementations, the retention straps work by holding down DIMMs with three points of contact: two at the anchor points holding the DIMM retention arms tight to the DIMM and a third on the top and center of the DIMM. Apacer claims this three-point method beats competitors’ two points of contact, which is assumed based on squeezing the retention arms tight to the RAM.

This RAM seatbelt is made of a flame-retardant polysiloxane (silicone), which claims durability at the intense high and low ends of the thermometer, up to 200 degrees Celsius. It has also been tested to meet military-grade certifications MIL-STD-833K and MIL-STD-810G for shock and vibration resistance. Apacer’s RAM straps are compatible with all modern motherboards and will play nicely with UDIMM, RDIMM, or ECC UDIMM modules, ensuring a good fit for any deployment.

    Is this a real problem? Because when I look up "ram knocked loose during transport", 100% of the search results are for the pickup truck.

    Former systems builder here - no it really isn't.
    The only time we'd ever see RAM not fully seated was due to a phenomenon called 'chip creep'. This refers to the 'creepage' of circuit boards that are connected to a motherboard that experience heating and cooling cycles very regularly (more than once a day, for several years). Heating and cooling creates expansion and contraction of the two separated boards at different rates, which creates a microscopic movement between the boards. Over time, they will eventually creep out of the socket.

    This is a rare condition, and personally, I feel like this is just a waste of materials. What would make so much more sense to me would be to re-introduce the dual latch DIMM slots again instead of those ultra cheap one-sided latching DIMM slots. The whole point of the dual latch was to prevent chip creep by physically holding the DIMM with a plastic latch perpendicular to the board, creating a physical brace to prevent the board from lifting out of the DIMM slot.

    P.S. - You almost always see dual latch DIMM slots on server hardware, where they don't skimp as much.

    the ram lock mechanism is arguably the strognest "hold" in a system outside stuff actually screwed down.

    look at the amount of force it takes to seat em and tell me thats coming lose if done properly :|

    In the 20 years I’ve built and shipped computers, I’ve never seen RAM come loose during shipping.

    Heavy graphics cards and CPU coolers yes, but not RAM.
