Corsair boosts a four-stick 32 GB DDR4 set to 4333 MT/s

Super-fast memory is great, but more often than not the speediest kits are made up of only a pair of relatively-small-capacity modules. Corsair's latest Vengeance LPX set is made up of four 8 GB DIMMs clocked at 4333 MT/s in order to give speed freaks a combination of capacity and bandwidth. The company claims that this kit is the world's first four-stick kit at that speed, and that the modules are built using hand-sorted and binned Samsung B-die ICs.

The kit (dubbed CMK32GX4M4K4333C19) runs CL19-26-26-46 timings at its 4333 MT/s clock speed and requires an input voltage of 1.5 V. The set is compliant with XMP 2.0 for one-click overclocking on compatible motherboards, but given the extreme speed and voltage rating, we'd expect more than a bit of manual tuning will be required from most systems to get these DIMMs running at those speeds.

Corsair demonstrated the kit running with all four of its DIMMs in dual-channel mode using Asus' ROG Maximus X Hero Z370 motherboard and an Intel Core i5-8600K processor.

Corsair says the Vengeance LPX DDR4 4x8GB 4333 MT/s kit will be made available to "elite overlockers and PC performance enthusiasts" in December. The sparkling performance comes wrapped in subdued black aluminum heatspreaders. The company didn't provide any pricing information, but given Corsair's premium branding and the performance on tap, the kits will likely not be cheap. The Vengeance LPX set comes with lifetime warranty coverage.

    Nice! Screw the price.

    Cool!. I can type “screw”.

    What no super fast 16GB dimm sets yet for desktop? Servers already have 64GB single dimms. This is so Meh to me.

    That’s a lot of voltage.

      Is this DDR2 in disguise like Trump is in disguise as a human being?

        • mcarson09

        You’re confusing Trump with HRC the witch.

      • DPete27

      No kidding, and ONLY twice the frequency of DDR3 nonetheless.

      No it isn’t, do you even DDR4 bro?
      My G. Skill DDR3000 kit uses 1.5V too, this kit runs at *much* faster frequencies, yet uses the same voltage.

      edit- I think I posted in the wrong thread, every post is negative.

      You are a big DIMM!

    Meanwhile, based on corsair’s own website MSRP and using a 2x8GB Kit, 97% of the performance 4333MT/s offers is available from affordable 3200MT/s kits at around one third the price.

      I regret that I settled for affordable RAM when I built this PC, the commonly given advice was to not spend too much because it wouldn’t matter anyway. Well now I know that it does matter for when I need the performance most, so I’m not making that mistake again, especially considering that any PC I’d build now will probably last even longer than my current i5-2500K build

        Well unless you own a Ryzen based sytem you’re never going to get additional performance that’s over the margin of error with these super high speed kits compared to DDR3000~, outside of a handful of applications.
        Super high speed kits like these are mostly good for posting sshots of memory bandwidth benchmark and the prices these kids go for make it a bit silly to pay so much additional money when they offer so little performance uplist in real world applications(including gaming).

          That’s what everyone thought back then as well, yet now we know that some of the most demanding games are very sensitive to memory bandwidth and latency as well, *especially* for their worst case performance. GPU performance is still more important in most situations so for a particular budget it always makes sense to prioritize the GPU, but if smooth high framerate gaming is what you want then you should not be cutting corners on RAM

            Which titles?

            • Firestarter
            • 2 years ago

            hard to benchmark multiplayer ones

            • Mikael33
            • 2 years ago

            So you can’t back up your claims then? If the gain was consistent and repeatable and not within the margin of error you would be able to find a way to benchmark it to show that, if you aren’t confident enough to benchmark them then you can’t be also confident that there is any scaling going on with memory speed in said multiplayer games.

            ARMA 3 is definitely affected by memory bandwidth, but it’s an outlier as far as I know. It’s a very different engine from most games out there. Lots of simulation going on with huge maps (Altis is 270km²) and it basically only uses 2 cores.

            Battlefield 1 is quite affected too. Average FPS doesn’t change much, but the 99th (and 99.9th) percentile sees improvements of 10fps for each 800MHz of RAM. (1600 to 2400 to 3200).

            Arma 3, even single player There are articles about it on this website.

            Edit: whoops, missed travbrad’s post.

            • Mikael33
            • 2 years ago

            Duh, I think I accounted for Arma 3 by stating a handful of applications benefit from higher memory performance, therefore if you almost exclusively play Arma 3 go ahead and buy the fastest memory you can afford 🙂

            You don’t need factory overclock memory though unless it is paired with a aggressively OC CPU.

            The fastest JEDEC-spec DIMMs are sufficient enough for any gaming needs with a stock CPU.

        The price difference between a standard 1333MHz RAM kit and 2133MHz RAM kit back in the Sandy bridge days would have actually allowed you to upgrade to an i7-2600K and still have change to spare.

        The other problem is that most Sandy Bridge chips wouldn’t reliably run RAM above 1600 anyway, and although 1866MHz was usually a safe bet if you used sloppy timings and dropped down to two sticks only, it wasn’t exactly a guarantee.

        So yes – Haswell, and Ivy – definitely benefit from faster RAM to some degree in some situations, but for the most part, you only worry about buying exotic RAM once you’ve allocated budget elsewhere first (CPU, GPU). These days, the “base” RAM is 2133 and it’s generally accepted that you can get performance gains all the way up to 4000+, but that the sweet spot between exponentially increasing price and diminishing performance returns lies beween 2666 and 3200, with 2666 RAM being about the cheapest stuff you can find now.

        I bought 2800mhz with my 6700k build when there was little evidence that anything beyond about 2400/2666 would help. I paid maybe a 10% premium over 2400mhz at the time (~$115 vs $105 for 16GB, right at Skylake release a bit over 2 years ago).

        It seems now 3000 might be worth it, but I’m not sure I feel that screwed over a percent or two in performance.

        If I had paid a 300% premium for 3200 at that time I’d be feeling pretty stupid today.

    “elite overclockers and PC performance enthusiasts” means expect to read stories about “breaking records” and see YouTube videos of people who shout “4333!!” repeatedly, but don’t expect it to be on shelves or in stock at Newegg any time soon.

    That’s the second best version of [url=https://www.youtube.com/watch?v=oJdBBpsFk0M<]Four Sticks[/url<] I've heard.

      THERE ARE! FOUR! STICKS!

        I didn’t ask you how many sticks you see, I asked you about the Federation’s defense plans for Minos Korva.
