What frequencies and size of RAM you use is dependent on the IMC (Integrated Memory Controller) on the chip and not the MB (if the board officially supports it). High frequency RAM say at 4000MHz and 64GB is IMO too much to ask of the 2700X CPU atm.
Both Intel and AMD are the same and it depends on the sample you have (Silicon Lottery).
The Crosshair VII Hero and 2700X combo are about as good as you can get and stability very much depends on your choice of RAM.
For RAM it is best to consult with the MB QVL as to what combos have been tested and therefore known to work.
Best IMO are DIMMs with Samsung b-die chips @3200MHz (2x8) for 16GB or (2x16) if 32GB is required.
If you choose OC RAM beyond JDEC standards then pre developed profiles don't work. (XMP and D.O.C.P)
With OC RAM you have to tweak Bios carefully with respect to Primary Timings and DRAM Voltage. There are apps to assist in obtaining SPD stability such as Thaiphoon burner and DRAM calculator.
Another suggestion is to first test with just a single DIMM to test for stability then add the other modules. You may have to up your DRAM Voltage, modify SOC and LLC depending on your PSU efficiency. Always best to get the CPU stable prior to OCing your RAM.

I have a similar kit to you but it's 3333C16 LPX Vengeance. It worked from the get-go for me, but on RVE10 and i7-6950X. I only clock it to 3000.
Edited to add: I had to reseat the memory 4 or 5 times before I got it all recognized. But after that, smooth sailing.
