    https://pcpartpicker.com/product/Tj...-1-x-16gb-ddr4-3600-memory-f4-3600c19s-16gvrb

    So the caveat is that the memory is actually rated as 3600mhz 19-20-20-40. Was unable to get it stable at the 3600mhz speed with DOCP profile on my x470 Asus Crosshair VII Hero (Wi-Fi). So started dropping the frequency and tightening the timings. So far have gotten it stable 10 passes of IntelBurnTest on Maximum at 3200mhz 14-15-17-21. Another caveat is I'm using two sticks [from separate kits] in dual channel mode on the Asus x470 Crosshair VII Hero, so that may help with the stability.

    1. First set the DOCP Standard profile.
    2. Second drop the frequency to 3200mhz.
    3. Third set the DRAM Voltage to 1.4v [XMP 2.0 supposedly goes to 1.5, so 1.4 should be safe but YMMV].
    4. Fourth set the CPU SOC Voltage to 1.1v [DRAM Calculator recommended the 1.1v at max for this kit].
    5. Fifth enter the DRAM Control submenu and change the latency to something like 16-18-18-36.

    Save this and reset.
    Run 10 passes of IntelBurnTest on Maximum overnight to ensure stability, then drop the timings down and retest until you find the limit the latency can be tightened.

    I have some of the 2x8Gb kits of these with same timings. Great CL14 result there really... I have also seen confirmed B-Die pulling similar numbers at slightly lower voltage.

    Just got 14-16-17-22 this evening on the IntelBurnTest. Going for 14-15-17-22. Personally never seen DDR4 3200 get RAS Active of 22, heck B-Die is like upper 20s or low to mid 30s IIRC.

    The sticks are Hynix, C Die [CJR], 2 rank, etc.

    Reason thinking these are a hot deal is that B-die run on average $70 more per 16gb kit, and the B-die usually seen are 2x8 which limits your total system ram to 32gb on most x470 and z370/390 boards. Also since these are lower cost you could potentially go 64gb out the gate on your build if your budget can flex $80-120 [depending on current pricing discounts etc].

    Nice way to get dual rank 32Gb with those timings on a Ryzen.. that's extremely good.

    14-16[15]-17-21

    Was able to tighten the RAS Write Delay to 15.

    Sure will take a look tonight. Essentially set the XMP then change the items in the OP.

    Oh nice! I thought you mightve been going deeeep into all those subtimings and things that 98% of people dont even know what they mean (me included, hehe)

    Nope, just set docp standard, drop the frequency, then up the voltage and set timings.

    DRAM Voltage to 1.4
    CPU SOC Voltage to 1.1


    Screenshots attached.

    Quick Q, why these have such high timings? I remember getting like single digits timings back in the day.

    Sorry but I am confused.......

    whats the point of paying for 3600 speed ram and then having to DOWNCLOCK it by 400mhz just to get it running stable ?

    Don't MOST people buy lower speed ram then OVERCLOCK it via XMP to speed it up ?

    I know thats what I did, however, I have a different system than you, but still...

    Please explain the logic in this plan if you don't mind :D

    I'm pretty sure 3200Mhz at Cas 14 is faster than 3600Mhz at Cas 19...that's the logic.

    DDR4 3200 CAS 14 is usually the sweet spot in most PC benchmarks I've seen. Being able to achieve that at less than what you'll pay for most DDR4 3200 is what makes this kit a deal; at the time the kits were purchased they were like $70 less than comparable Samsung B-die.

    Gaming I assume wants lower latency

    Fwiw, I got a 2x16GB kit of this stuff for $135 after a coupon from NE. Won't run 3600Mhz with my 2600 but am working my way down to Sherloc's timings.

    Exciting.. Keep us posted. I can't wait to see what it'll do on Zen2... also will look at 32 or 64gb if prices stay sane.

    You won't able to reach 3600mhz with Ryzen 2000 no matter what, You need Ryzen 3000 that allow you reach higher memory.

    I used have old 2600 hit wall 3533, Now I have new Ryzen 3600 can reach 3800@ fclk 1900 1:1 ratio with same ram I had before with 2600.

    2 cents.

    Should this thread be moved to Hot Deals Discussion? Anyone around who can still do that?

    Noticed the thread start date and was like, am I in the right sub forum? :D

    I can't wait for the deep investigation. IMO I think Ryzen one with super RAM will come towards %10 of Ryzen 3000 @ same speeds! Place your bets?
    Loving all the input here at the [H]!!!!

    3733c17 is ideal, havent seen any reviews with that spec

    3200c14 and 3600c16 are achievable with numerous kits.
