    Just plopped the 3800X into my Asus mATX B450M-Pro.
    Dialing in the Memory right now.
    1900MHz IF seems fine, tried 2000, got a hard lock. Had to remove the battery. ;)
    3800 mem, Cas16 so far, 1.375v. ( I have 2 sticks of 8GB GSkill 3200Cas14)

    Wouldn't take Cas17 by what it says in the Bios timings. Just refused it and stayed at 18.
    I Went from 18 to 16 fine, have just left the rest on auto for now, changing one by one.

    Dram calculator comes up with C14 timings and 1.45v recommended voltage...we'll see

    Running a couple of memory test passes after a few changes.

    Still on the 1.0.0.3 AB bios.
    51°C and 1.4V in Bios doing nothing, stock box cooling.

    Waiting on a couple more waterblock connectors. :) (One i was going to use has a wiggle i dont like, its a previously used one, also need another 90° tube to tube connector)
    Going to have the pump/res hidden in the dual 5 1/4 inch bay (Fractal design Arc Mini R2, I bought this a while ago, as I have one already and really, really liked it, both black with windows.)
    The Large 240mm is up front. Dual Push-Pull Noctuas up front (4), one Noctua on rear.
    Making sure I have positive pressure in the case.

    So, no one else having the same issue with Windows Power saver plan resulting in lower latency vs all other power plans? Guess I need to reset my power plans again....

    Hi. Have seen your post ;)
    Just not got there to testing that bit yet.

    edit : what software are you using to test the latencies ?
    edit2 : my aida64 test time has run out lol.

    Why are you wondering about this ,I am just curious.I do not think there is any benefit in any games or applications.If you want a lower latency just change interrupt power setting to processor 1 instead of default.Boom drop a few ns without doing anything. Miracle cure for lower latency .
    I would really like to know why people want to drop the latency on Ryzen ,is it just for the number ,then I suggest do the above.

    OK, so I'm now a proud owner of an Aida64 license :)

    I get 63.3ns (sometimes 63.2/63.1ns) no matter which power plan i use.

    I have disabled the "Memory power down" in the Bios, and enabled the "Gear Down".
    Running 3800C16 16-16-16 1.4v.
    I'll get an Aida screen shot added just below, lol ;)

    Good stuff ,you can get the key on ebay for $1.99 for Aida64 Extreme .

    Are you going to test some games and post your results,just asking.

    Seems to be. :)

    The AB bios has weird CPU voltage spikes (1.475 to 1.481v for 5-10s) and the stock fan is always changing speeds.
    Only little fan speed changes, but audible. there is nothing else making any noisein there apart from the PSu, which is basically silent.

    its GSkill Memory, F4-3200C14D-16GVK

    Yeah. Really waiting for the ABB bios though before full testing, and the water cooling last bits.
    Even though, with the stock heatsinks, they arent getting warm at all. Both the 2700 and the 3800X stock fans blow enough on them to cool them a bit.
    Should probably run steam and update it, and then See if Gog is installed.

    So, 3800C16-19-19-19-39-56 @1.35v.
    Thats not bad.
    CAS is the most important (C16), then the following ones.

    If you haven't tried out the Ryzen DRAM calculator, i'd try it as a guide, and change ONE memory setting at a time, and reboot in-between, and if time and boredom permits, a memory test in between too. ;)

    I never even thought about looking on Ebay for something like that and now I have a copy for $1.49.

    Gerard: When you overclock your memory, and tighten the timings, subs included, it should increase throughput and lower latency. I don't understand the reason for the rest of your post. I was simply asking if anyone else was getting lower latency from X power plan vs Z power plan as I was experiencing.

    Thanks EvilDead, must be my power plans are corrupt again somehow. Nice timings you have there, very jelly. ;) I'm running B-Die as well, I'm memtest stable@ 16-18-16-32-48-1T, any lower and she throws errors. I'm still/always tweaking it though. :) Thanks again, I appreciate your time checking that for me.

    those timings are a bit better than the dram calculator i have 69 ns latency i think its enough.

    I'm seeing 2501 as the latest Bios on that link ?

    edit : Seeing 2606 on another PC. My end. ;)

    Yeah. Bascially, for Ryzen 3000 its getting the memory the same speed as the highest possible IF Clock and lowering the latencies as much as possible.

    Has anyone seen a chip do better than 1900MHz IF speed ?
    Even with upping a certain voltage ? (I'm asking because i don't know which voltage would be applicable).

    Crazy how cheap you can buy some things.I never thought about ebay before until it was mentioned in games section.Bought the Control/Youngblood games for $23.00USD.
