The rather long lifespan of DDR4 memory has allowed manufacturers to learn how to build modules running at speeds and voltages well above those specified by JEDEC’s standard. Nowadays, leading makers of modules offer DDR4 memory rated for interface data rates of up to 4600+ MT/s. At Computex, GeIL demonstrated its Super Luce modules rated for 5000 MT/s, but will such modules hit the market?

Samsung’s legendary B-die chips enabled many professional overclockers to set records by hitting ultimate speeds. But while high-quality modules with cherry-picked chips are required to set records, they are not the only things that are needed for ultra-high speeds. Far not all CPUs and memory controllers can work in DDR4-5000 mode, GeIL says. In fact, only about 2% of processors can do this, so out of 50 CPUs only one can potentially hit such an extreme memory transfer rate.

Considering how rare processors with extremely potent memory controllers are, GeIL does not think that it makes a lot of sense to produce DDR4-5000 memory modules commercially as very few end users will be able to take advantage of such modules. So while GeIL (and probably other makers of advanced memory modules) can offer DDR4-5000 and even faster memory modules, it is unlikely that such devices will be made widely available.

    This is a very interesting product for sure. I assume the manufactures that want to continue to push the limit of DDR4 only have one feature to improve upon left. Other than price of course that would be timings but idk how much headroom is reasonable left to decrease times. Even if they are able to reduce timings will it matter with what presumable little changes are possible.

    2% is more than the 1% (and particularly .5%) who control a vastly disproportionate share of the wealth (particularly "financial wealth").

    2% is plenty to provide review sites with RAM to minimize CPU bottlenecking of GPUs for GPU testing. At the very least, such RAM could be provided to the top sites.

    I have a hard time not reading "Super Lice" when I see certain GeIL products.

    Sounds like something you'd buy and it wouldn't come close to the factory overclocked rate.
    You'd complain and they'd say you weren't the lucky 2% and blame it on your cpu.
    I guess we have to buy 50 cpu's just to verify that they aren't lying ?
