Samsung has quietly added 32 GB unbuffered DDR4 memory modules to its lineup of products. The UDIMMs are based on the company’s 16 Gb chips, which were introduced earlier this year that are already used for 32 GB SO-DIMMs as well as 64 GB RDIMMs.

Samsung’s 32 GB UDIMM is rated to operate at DDR4-2666 date rates at the DDR4 standard voltage of 1.2 V. Samsung does not disclose timings, but since the company sells its own memory modules mainly to large PC OEMs, it is highly likely that the 32 GB UDIMM uses the standard JEDEC latencies for DDR4-2666 (i.e., CL17 17-17 or higher).

32 GB UDIMMs will enable system integrators and PC enthusiasts to build PCs with 128 GB of memory using motherboards with four DDR4 slots. Now it's worth noting that current mainstream CPUs and motherboards are only validated for 64 GB of memory, but eventually we'll either see current platforms validated for the larger DIMMs, or the next generation of platforms will support them from the start.

Samsung’s 16 Gb DDR4 memory chips are made using the company’s 10 nm-class process technology and, according to the company, modules that use these DRAMs are more energy efficient than DIMMs of the same capacity that rely on a larger number of 8 Gb devices.

Since Samsung already lists its 32 GB unbuffered DIMMs featuring the 16 Gb memory chips, it is highly likely that these modules are already available to at least some of its customers. Pricing of the modules is unknown, but a 32 GB DIMM costs around $300 these days.

    Yup. Go to the samsung page, and they've got an image of a 2 rank dimm that fills the space fully. Unfortunately at a skewed angle and not much good for an article lead image. Reply

    That's from current Samsung's shrunked process chips. Current chips make full use of the whole full length DIMM for dense server modules (load reduced dimms) Reply

    mehh is a memory maker, not matter how "advanced" and cost reduced it is for THEM 9/10 they do NOT pass these savings on to consumers, if anything they use this as an "excuse" to charge more such as single side DIMM with same amount of memory and so forth.

    DDR3 came out the gate at crazy pricing, DDR4 was supposed to be notably less costly to produce and yet pretty much sat at around the same pricing overall (DDR4 started off real decent pricing, did not last long)
    DDR5 is likely to follow the same trend as well, start off slightly cheaper and then jump through the roof pricing wise.

    I personally do not understand memory pricing, seems every "new" generation that becomes far less costly to produce with likely very awesome yields becomes more expensive $/gb with very few exceptions that is IMO of course.

    I can't remember, are you the same guy that makes these ill-informed rants every time new memory comes out? Reply

    Check the sign of this exponential development:

    The result may surprise you.

    I agree. You don't understand memory pricing. Reply

    "but a 32 GB DIMM costs around $300 these days." 32GB RDIMM? Be more specific. Reply
