G.Skill 3800 MT/s SO-DIMMs put lightning in tiny bottles

Laptop memory slots are the usual domain of SO-DIMMs, but a seemingly-increasing number of console-size-and-smaller gaming PCs are also using the parts. G.Skill's latest memory is designed to bring high memory clocks to gamers playing RAM-speed-starved titles like Arma 3. The company claims its 3800 MT/s DDR4 Ripjaws SO-DIMMs are the fastest modules available in the form factor. The company unveiled sticks in three speed bins, all using Samsung B-die integrated circuits and operating at 1.35 V.

The fastest kits are the aforementioned 3800 MT/s modules. These speedy SO-DIMMs run at CL18-18-18-38 timings and are offered in a four-module kit with a total capacity of 32 GB. G.Skill demonstrated the sticks running at their advertised speeds with an Asrock X299E-ITX/ac motherboard and an Intel Core i9-7900X processor. The company is also offering up 32 GB, four-unit 3600 MT/s kits with tighter CL16-16-16-36 timings. The third and final speed bin is made of 3200 MT/s SO-DIMMs with the same CL16-16-16-36 timings. Four-stick kits in this speed grade are available with total capacities of 32 GB or 64 GB.

G.Skill says the little speed demon modules should be available in December, though the company wasn't ready to talk about prices just yet. Given their place at the head of the SO-DIMM speed table, their association with quad-channel-RAM platforms, and current DRAM market conditions, we'd expect the kits to be pricey. G.Skill backs all of its memory modules with a lifetime warranty.

    Proof that even very fast RAM in extremely high-density configurations doesn’t need a heatsink.

    Can manufacturers please offer decent RAM for desktops without heatsinks? I’m tired of having to eliminate two-thirds of the RAM whenever I’m buying the stuff because it would otherwise foul a CPU fan, make slots unusable or hinder the airflow in a compact mITX build.

    Ok, so these SODIMMs have the same timings as desktop sticks at the same speeds and the same voltages……..why can’t we just switch everything over to SODIMMs? (laptops and desktops)

      You can’t do that!

      They are *SO* *DIMM* that you’d never be able to see the RGB LEDs!

        You say that like it’s a bad thing….

          I think you missed the pun.

      They are smaller, more fragile and probably cost more to make. As a result they probably have lower oc headroom.

      You should compare temps for smilarly specced (on all the the things that have an impact on RAM) laptop and desktop at default speeds. Guess what has a hotter memory…

        Considering RAM “heatsinks” are almost entirely unnecessary (as shown here with 3600MHz SODIMMs doing just fine with no heatspreader) it’s safe to say that heat isn’t a significant factor.

        Sure, there are higher clocked desktop sticks on the market, but I’d wager a guess that’s because SODIMMs go into laptops which have no ability to OC RAM past the max supported speed (2666MHz for Coffee Lake). Therefore, all the higher binned chips get put on desktop sticks where they’ll actually sell and be utilized. Whether there are any other real limitations on the max speed of SODIMMs is above my level of insider knowledge.

        In what way are they more fragile?
        Why do they ‘probably’ cost more to make? A smaller PCB could make them cheaper!
        Why do they ‘probably’ have lower OC headroom?

        Throwing a lot of probables into the pot is another way of saying I really don’t know but I am going to guess and act like I have a clue.

      This reminds me of how large die size DRAM are dead now. We still don’t have 16Gbit DDR4 even today.
