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?).

Oh wow that's horrid.  Just give up and get some 2x16 3200CL14 b-die, it's compatible with everything and the cpu will bench about 10-20% better than what you have now.

Except now I'm buzzed a bit. :)  If not for the $400+ cost of the CL14 3200 MHz b-die parts, I'd have them on the way via prime or newegg.  Not gonna drunk shop though.  It can wait until the morrow.  I just hope it's not the mobo itself having a problem with the memory channels going full speed.  But if so, EVGA has been kind to me in the past.

Ohhhh yeah I missed you're wanting 64gb.  Meh.  Two 32gb kits combined are not going to run stable on straight XMP, imho get a 64gb kit.  Pretty limited QVL on those:
 
https://www.gskill.com/configurator?page=1&cls=1529635169&adSearch2=Capacity%C2%A764GB%20(16GBx4),&manufacturer=1524715213&chipset=1539226140&model=1539226162
 
The Flare-X kit was $480 up until it went out of stock a couple weeks ago:

The ripjaws and trident kits were in the $500's and haven't been in stock for a while.
 
Unless you REALLY need 64gb, the Trident Z 32GB kit for $240 is reasonable, though other versions have been less.

Yeah, *want* 64gb.  I really don't need it.  32gb will be fine.  But the G.Skill Trident Z kit at the top of the list doesn't actually exist on Newegg.  The current part (https://www.newegg.com/p/N82E16820232378?Description=F4-3200C14D-32GTZSK&cm_re=F4-3200C14D-32GTZSK-_-20-232-378-_-Product) is $320 and is not sold by Newegg but one of their partners from Asia.  And I really really don't want RGB.  It's a clean, quiet build.  But I could get the Trident Z RGB version on Amazon for $260. Hmmm.

It just went OOS. The desirable b-die goes in and out of stock constantly.  They load new stock throughout the work day, pacific time.  I had to wait a couple weeks for the trident Z kit of 2x16 4000CL19 that I wanted.  
 
The Ripjaws kit should normally be about $220 and the white/silver Z kit $230.  Flare X $215.  Just check this search a couple times a day and be patient:

Hard luck ! As many memory makers (or some of their kits) aren't listed on the QVL list of motherboards vendors because it's simply impossible for EVGA or other companies to test each type of memory since they are too numerous... Maybe the best is to sell your current 4x8Gb Gskill kit to buy another one, i've got the same motherboard as you and the same cpu for one year and my Ballistix Elite isn't listed on the QVL list neither and i never encountered any problem at all to make them work at their xmp profile and even overclock them without increasing their voltage...

Ballistix Elite is high binned Micron E-die, their bins may be somewhat conservative too, it is newish but developing a very good reputation.  Expensive.  Not surprised to hear it works well for you.

Thanks ! Yeah totally satisfied with my 4x4gb kit (not listed on the QVL list) rated at 3200mhz 1.35v cl16-18-18-36 2T xmp and overclocked at 3866mhz 1.35v cl18-21-21-41 2T

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?
