    Low oc.
    Mine cheapo 4400c19 vipers with not best oc MB, 370 taichi, does 4100 15 15 15 31 280@1.53v.
    Different board, same memory goes 4400 c16 16 16 34 but 1.62v.
    Mems are around 150-180e for 2*8Gb.
    They seems best good value b-die on market now

    Well, you compare the OC of 2 x 8 GB vs 2 x 32 GB. That's totally different story Mate :)

    Not bad for 64GBs (2x32)--which, btw, I would not recommend for most people because it's simply not going to be used in any game--it's literally too much ram for most people, imo. Expensive, specialist applications might use that much ram, or even twice as much if not more. I have two sets of the Viper Steel DIMMs, each 2x8GB. The kit I'm currently using is an XMP 3733Mhz kit; the other is a 4400MHz kit (saving for later.) With the 3733Mhz ram in my X570 Aorus Master mboard, I'm using the following timings @1.35v and 3733Mhz, CL 16-19-19-19-39-68 1T, Gear down enabled. (Stock XMP timings are 17-21-21-21-41-68) Runs like a top even though these are all better-than-factory timings. I let the system decide each boot whether to run Gear down or not--setting it to auto in the bios--and it always chooses Gear Down enabled. I've run a lot of tests with GD disabled, but the enabled setting seems a bit faster. I might eke out a bit more performance--someday--if I feel like playing with it. Nice ram, However--very nicely priced, too!

    You are actually loosing performance over 3600/3733 on ryzen so there no point in these 4400 overpriced ram you guys are tlking about.

    Euhmm, there is if you are going to overclock your ram manually, then you can lower the frequency to 3733 and do CL14 or even lower...


    I got these in 3733mhz/CL17, worked flawlessly with r5 3600 on xmp settings !

    When I got my micron E Ballistix 3200Mhz a year ago, the difference between 3200Mhz and 3600Mhz was huge. But today 3600Mhz ram is much cheaper.

    I wonder if the Zen 3 CPUs will benefit from RAM above 3733Mhz, if so, then it would make sense to buy 4000Mhz~ RAM if you plan to upgrade to Zen 3.

    That'd be nice, something like Infinity Fabric at 2000 so DDR4 4000 could be a thing then, RAM chipsets and timings being a big part too whether this fully surpasses the better 3600's and lower timings or manual overclocks to get that latency down further.
    3800 as a in-between and 1900 IF speeds could also see some gains but we'll have to see from benchmarks and reviews or other reports plus if AMD is actually going to increase the infinity fabric or if the CPU itself and advancements will already make a nice little reduction on latency and improvements of the cache and how these little core clusters work.

    Bit more complicated when you don't just have the raw speed but also the latency and how that affects final performance, it can still be pretty good for Zen2 but a combined hardware improvement on the CPU and additional infinity fabric speeds both could give it a nice little extra boost as well over existing gains compared to the Zen2 series. :)

    Something that will be interesting to read up on as these become available plus a possible insight into Zen4 and DDR5 perhaps if that's next however initial DDR5 modules will be and support for these before I don't know Zen5+ or Zen6 anything could happen after that.
    (There's probably a roadmap of some sort at least internally for what AMD is planning out here, will be fun to see how it continues.)


    EDIT: Yeah that would be something, Infinity Fabric at speeds around 3000 for DDR5 6000 or wherever it'll be but then that completely disregards the CPU side advancements and a possibility for AMD to diminish the need for this by having additional improvements and reducing latency down through other means.

    But why not both, faster is faster after all. :D


    Though this also completely disregards a ton of hardware challenges and how much AMD can actually scale infinity fabric speeds and what's needed for major increases plus overall strain on the hardware and overclocking and well, a lot of factors essentially.

    Have me some GSkill 3600mhz at 3800 with an infinity fabric of 1900mhz. 16-19-19-38-58-490 1T. That's 64GB from two different sets.

    Same setup I threw into my ripper. 128gb 3600mhz same timings with an additional third 64gb set and they all play nicely together.

    Unless Ryzen 3 gets its internal clocks higher at stock there is going to be no need for some of these 4k plus specced DIMMs.

    I guess if you're buying into the "future" then sure?!? Just doesn't make sense to me to break that coveted 1:1 speed barrier for specifications same. No performance is gained as latency shoots through the roof.....

    I like memory comparison between Intel and AMD.
    Why AMD write speed is half the read speed (and Intel write speed)?

    If you read the review you'll find out.

    If the new 4700G is anything to go by then yes Zen 3 should see an uptick in performance with higher ram speeds. As this CPU isn't using the chiplet design instead its using the old monolithic approach. Tests have already been done and the chip can easily handle 4.4GHz RAM speeds. Also helps massively for the iGPU too.

    Though actually I only see AMD using the monolithic approach for their APU's rather than their HEDT chips. Makes more sense rather than limiting the ram speeds and ultimately holding back iGPU performance. They will more than likely keep using the chiplet design in order to push higher core/thread counts and keep prices down by making much smaller dies.

    We are using Viper 2x8GB 4400c19 for this:

    Vipers 4400c19 is pretty good, and are actually very cheap!

    Thanks! I missed this sentence:
    The CCD/IOD link is 32B/cycle while reading and 16B/cycle for writing, so that’s why the write performance is halved.
