Yeah, nothing worked and even get to POST.  I had an evening of drinking Gin Rickeys and contorting to clear the CMOS every couple of minutes.
It was a 2x16gb kit so they are a matched pair, supposedly.
I'm going to have to get some better memory to bump up the speed of it apparently.  The Sniper X memory 16GB modules do not agree with the Z390 FTW at any speed I tried above 2133.   I put the VSA and VCCIO up to 1.35v at 3600 and 3200.  No dice.  I left the memory timings on auto and set the frequency to 2667 and 2400 w/o luck.  It runs fine at 2133, so I'll leave it there for now.  I may look at some of the other Sniper X timings that are certified for 2667 perhaps and try to apply them directly, and try the highest 1.2v rated timing (is that 2667?).


Buying antother memory kit most likely won't help. The imc on your cpu is most likely weak, and the only way to correct that is to get another cpu with a stronger imc. Gotta love silicon lottery. Did you also try running your ram at 1.35v along with the vsa and vccio at 1.35v?
 


Yes, I did.  And I hope you're wrong about the CPU. :(  I'm more hopeful that the memory is either not actually matched or that one or both are simply not up to the task of being run at faster than 2133.  Since this RAM was the budget buy part of the build, that seems to be more likely.  Also, a teachable moment for me.  I need to read the specs better and pay attention beyond the "Ooooh, ahhhh, that's 3600 MHz.  And it's cheap!"  Cheap for sure.  But no bargain.


If it is the case that a quality set of 2x16gb CL14 3200 DIMMs don't work any better, I will likely at least be able to run with 64GB at 2133MHz.

If you're not able to run higher than 2133 with another set of ram then I would highly suggest rma'ing the cpu as you should be able to run 2666MHz without any issues at all.

I spent hours and hours researching ram for my build early last year and still bought the wrong ram, then doubled down and bought it again to have 64gb. 
 
Just picked up the right ram last month, though it was a solid $135 cheaper than if I had bought it back in Feb '19.
 
I'll cut you a killer deal on a couple sets of F4-3000C16D-32GVRB, but it's not QVL'd for your MB.

These happened to pop up as a price reduction on my newegg wish list, they are 2x8 4000CL19 b-die with nice tight timings, for $112 a set.  You would almost definitely need to clock them yourself, but they are a good value, two sets for 4x8 at $224.

I just purchased a set of 2x16GB Ripjaws that came back in stock this morning on Newegg: F4-3200C14D-32GVK.  We'll see if my CPU can deal with the faster memory or if I have to try to RMA a 1+ year old cpu with Newegg, as I built this in machine late 2018.

Great kit, hopefully it works!!

I will let y'all know.

I received the memory today after a couple of days of delays due to the snow here in WA.  I plugged it in just now, went for broke and enabled the XMP Profile #1 at 3200MHz, and put VSA and VCCIO at 1.2v and she goes!  👍

Hey that's great.  The b-die is really great memory even in a midrange bin like 3200CL14.  That bin is also compatible with almost everything and should be really stable.  You should see some major improvement in benchmarks, coming from 2166.
 
My 4000CL19 has been running really well over the past few weeks.
 
May want to try the SA/IO on auto and see where the XMP profile makes it set to.  Mine puts them over 1.3v on the new kit which was much higher than my old kit, so I've just left it like that for now.

I looked at them in the auto setting and after having read that the chipset tended to overvolt the VSA and VCCIO a bit, I went with 1.2v explicitly.  The VSA was around 1.25 or more in auto mode and the VCCIO was 1.2v.  It runs ok so far with them both explicitly pinned to 1.2v.
