For instance, DDR4 3000 with CL14 is faster than 3200 with CL16. Not sure this is the entire picture, but had me curious.

Not sure where you find out if RAM is Samsung B Die or not. (It's so dumb that's a requirement for higher clocked RAM on Ryzen)

MAKE BETTER MEMORY CONTROLLERS AMD.

Bandwidth only matters if there is a lack of it, in which case the difference between 3000 and 3200 is going to be negligible.

Welch wrote:Yep, I'm aware of how RAM latencies work (albeit, a bit rusty), very good overview explanation of them. These were specs I actually cared about too much back in the day. I should have mentioned that I would be using 3200 regardless, no plans on using a slower frequency and hoping tghter timings will pickup the slack.
If things haven't changed too much, gaming or anything latency dependent used to be where tighter timings shined. I'm not sure if this is still the case, but I'd imagine it is.
So I know the whole RGB thing is a joke, but not to the wife who loves that her new B350-Gaming 3 has RGB and matches her Corsair RGB . $190ish for 16GB or $220ish for lower latency no RGB. Is it worth the extra 30-40 to drop down to 14-14-14-34. Would love to hear some opinions to sway my purchase.

If the wife likes RBG get her RBG modules. This is for your wife, who apparently likes shiny. Welch these modules like to shine (well glow vibrantly).
There is a Moana joke in their somewhere
She likes Shiny, but also likes her system to kick ass like mine. Now she is on the same CPU as me. Granted, I'm not sure she would notice the difference of the low latency in the near future lol.
Was just hoping someone had feedback on the real world difference of the high and low latency stuff, especially considering the Infinity Fabric on Ryzen.

Welch wrote:At this point we have just been playing Planetside 2 and Path of Exile. Once the GPU market is somewhat normal and we can get with more punch we will probably start playing Ark Survival again and a few other resource intensive games. I wouldn't say we have a target frames either at this point, just as much as I can get out of it. In my case, with my Freesync monitor, I'd shoot for maintaining 50+ in most anything I play. No issues with slightly lowering the graphics. I've got the Nixeus EDG 27, so 30-144hz on the Freesync range and LFC for below that.

-Always up to date. Asus ROG X370-F and Prime X370 Pro, which tend to run on the same firmware rev.
-DOCP tried first, and more often than manual settings. Manual settings caused all sorts of other issues on the Ryzen mobos, like dynamic clock speeds would go away, voltages would lock at maximums, just general weirdness. It's enough weirdness when overclocking that I run both Ryzen 5 1600's on Auto now.
-When CPU is on Auto settings and is loaded, it seems to run 4 cores at 3400 and 2 cores at 3700.
-The Ryzen 5 that runs Windows, where I can fire up HWMonitor, has logical cores 0 through 13, and 6 and 7 are disabled.
-If Dropbox had not taken away the Public folder, I would post a screenshot. Still learning image hosting alternatives.
My Ryzens are worthless if they aren't stable, so fretting about RAM is something I have to leave for others. That's difficult, as I'm as much of a tweaker as anyone else here, and although I refuse to be a "fan" of a company, many who are less strict with definitions would call me an AMD-lover / Intel-hater (which again, is not necessarily accurate, but that would be the perception.)

CPU performance has been degrading again and really hates AMD; 50 in the biggest fights is a bit of a tall order, but with 3200C14 and shadows turned down it should be close.

Disregard that, turns out model quality is the trick (animation LOD distances). Of course none of my testing caught that (until now) because I mostly wasn't testing with other players around, because they make test results inconsistent.
After turning that down to low, my framerate in big fights has about doubled, and now hardly ever goes below 60 (Zen at 3.25 GHz / 2666CL14, core count doesn't matter due to PS2 being only four-wide).

Welch wrote:Surprised that is all you are getting, your GPU is much more powerful than my 7850 2GB... What sort of res are you pushing out? I've been playing PS2 for roughly 4 years, sad to say almost exclusively. I just can't get into games because of time constraints with work and kids. I've done a lot of fine tuning to my PS2 over the years , I've got it running damn fine. The biggest jump was going from my i5-2500k to the 1600x as it simply smoothed out the jumps in frames. My rule of thumb for editing any game settings, native res is a must, lower or turn off any particle or shadows, especially when they don't change the gameplay or add anything useful. In most cases editing render distance is also a must, but sadly it seems that PS2 doesn't benefit from lowering it. So I do leave it on at least 4k if not maxing it out at least on my 7850.
