    since when is CL17 low? or even ultra low? maybe it is in terms of super high frequencies memory sticks?

    Timings are directly proportional to the RAM speed since they are measured in cycles.

    CL 17 latency at 4.2ghz is roughly equivalent to CL 8 latency at 2ghz. Plus the added bandwidth of the higher frequency RAM.

    On 4266MHz cl!7 is very very low. Remember you can still buy 1600Mhz cl11 DDR3 memory so in that contest it is very low.We are her still talking about less then 0.5ns cycle time and less then 8ns for first word.

    Curious to see some Aida64 results...As my memory is reducing speed after 3700-3800 while RTLs and IOLs are not tight also tRFC over 700(for these ultra-low latency mem..Wow :) )...I have degradation after 350 by far even 200-300Mhz cannot even compansate in terms of transfer or latency...
    Here's my memory running 3770 14-14-14-28-280 2T with 4 dimms on Z370 and 4040 cl16-15-15-35-400 2T Just see write and copy...
    All the same...IMO it's just a marketing w/o real world performance benefits getting over 4Ghz

    almost looks like you are maxingout the ringbus, have you tried setting the uncore even higher? (if thats even possible lol)

    Awesome! Any word on when the Threadripper version will be out? I know it is DDR4 and technically it should work on a X399 mobo, but there is that compatibility weirdness and most likely it doesn't work and is only for Intel CPUs.

    It be real cool to see what the extra 1066mhz and timings would do for a Threadripper and Ryzen based CPU in games and benchmarks.

    Not maxed can run synced with CPU ...but have to shave CPU OC to sub 5300 :))

    Well it depends.
    I agree is not a bottleneck having the memory at 3.8, 4 or more GHz.
    But someone has to push the pedal on the accelerator, someone does faster memories, and someone else will make faster memory controllers to take advantage of them.

    that make sense not sure why i didnt realize this., maybe my attempts to forget all things i know about computer tech is finally working:p

    Damn where were these when I built my system. Maybe I should just try out the timings and see if I get lucky.

    You would expect the bandwidth to go up even with looser timings on 4000mhz, since you're still seeing bandwidth scaling with the higher uncore even with looser timings at 3845, it would seem that coffee lake can't make use of 4000+ speeds unless you are setting the uncore past 5.3ghz.

    Nice chip btw, truely amazing.

    i feel like 14 at 3200 is kinda the sweet spot for ddr 4

    3200mhz is so 2014..

    4000 cl17 is pretty easy on CL, sky x and coffy L with b-die 3200cl14, 3600c15/c16 3733 c17 etc. Just add 1.4-1.45v :)

    4Ghz+ on Coffee is quite picky with 4 modules...on SkyX is walk in park...seems post some point with 4 modules the IMC struggles as write and copy are greatly reduced with 2 modules all is fine....
