    Since ZEN 2's official supported frequency is lower with 4 DIMMs than only 2 DIMMs, aren't 4 DIMM-Kits counter productive for high frequencies?

    There is a YouTube channel called actually hardcore overclocking that has some initial testing on zen 2 ram. So far the way to go is dual rank 2 dimm kits. Like you surmise, running with two dimms enables higher frequencies overall but per aho's testing, once the latency has been experienced to the dimm, you want as much capacity at the dimm to access. Previously I think from memory on precious zen platforms single rank ram worked much better, but the upgraded controller works well enough for dual rank to be beneficial. Because of the f clock decoupling however, you want to stick to the 1:1 range (up to the 3800 mhz of the kit in the article) where the ram speed matches the infinity fabric speed one to one. That makes this kit so good. Above 3800, the fabric clock is lowered. So the kit in the article might be the best zen 2 memory available.

    I would like to know if anyone has found a definitive review refresh on the advantages of cl(low number) vs cl(higher number) with ram nearly the same speed rating. I would also like to be refreshed on the advantages of DDR3 memory at a cl8 and DDR4 memory at a CL16. It seems to be an issue of major financial investment for gains that only the top tier buyers would appreciate.

    Is RAM scaling even that great on Ryzen 3000? The two reviews I looked at showed barely any improvement from 3200 C16 to 3600 C16. With one of them even adding that that massive cache size on the 3900x was likely reducing the need for faster memory.

    Sure but this is 3800mhz @c14, much faster

    Esp good to eliminate.1% lows in games

    There is not a single test out there that compares, say 3200 CL16 with 3800 CL14

    Quite frankly 3600 CL16 is not very impressive at all
    To me that's a "not that fast kit", at least on Intel

    Yes there is

    Techpowerup have done it

    You can also find similar tests for Skylake-X

    The key point is that all these distributed-die / mesh type architectures like higher interconnect speeds, far more that the old single die designs ever did

    Making one bit faster just moves the bottleneck elsewhere. But it will depend on the workload, of course - if you're doing something that fits in cache, memory speed is irrelevant. Over time it is likely to become more relevant as programs and data tend to get inexorably larger.

    This is obviously a for gamer product

    No work space would OC the RAM this far and up the voltage that high

    Yes, Games benefit, the more CPU intense the more they do

    Still not worth the upgraded cost foing from something like 3200 CL15, which is quite affordable, to maybe paying double or more the price

    Where is this SKU? Even emailing G Skill trying to purchase/find a vendor yields nothing.
