I have no problem buying different RAM.  I'm not financially limited in this build.  I just need to know what to buy.

I just went out and bought a x399 ASUS Prime motherboard.  Going to try it with the 128GB ram + 1950x 16 core CPU right now. 

Want to know the results when it's ready?

Many thanks again for the help!  If you tell me what to buy which is QVL for x399 ASRock then I'll buy it today (If Microcenter has it, I'll get it immediately and report back with the results on Saturday).

Not sure where you are at now, but to continue...

The way you cleared the UEFI/BIOS with the button is fine, that seems to be the only way to do it with your board.

The point of my suggestion was to see if all eight DIMMs would POST at their stock/default speed. Given your description, you tried to start the PC with all eight DIMMs with the XMP profile enabled. That is more difficult to accomplish than running the memory at the stock, lower speed.

If you could get all the memory to POST at the stock speed, you could go on from there. But I don't know where you are at now with the ASRock board.

If I knew which memory to buy that would guarantee that eight 16GB DIMMs would work, I would tell you, but I don't know what that is. We still don't know, I assume, if all eight of your DIMMs work at their stock speed.

All you need to do is clear the UEFI/BIOS as you described, with all eight DIMMs in the board, and see if it will POST. Did you try that?

Hi 128noGB,

yes please post your results about x399 ASUS Prime motherboard.

I bought a MSI X399 GAMING PRO CARBON AC and it arrive friday...I'll post the results soon.

Yes I have tried inserting the 8x 16GB DIMMs and letting the default stock speeds work.  That is the first way to test this in the first place.

128GB does not work with stock speeds.  128GB does not work with 1.3 or 1.5 or 1.7 BIOS. 

128GB does not work setting speeds to any interval, even 1866mhz, or regardless of any timings. 

128GB does not work with any voltage tweak, DIMM timing, anything.  I've tried it all.

I've replaced the ASRock x399 motherboard with a brand new one.

I've replaced PSU with a brand new one.  I've replaced 128GB RAM with brand new one.  I've replaced the AMD 1950x CPU with a brand new one. I've replaced the GPU with a brand new one. 

Nothing.   This motherboard simply does not work with 128GB of QVL RAM.  Period.

UPDATE:

After 9 emails to ASRock support, their response to me is this:

We did tried with G.SKill Ripjaws 8 sticks memory module without no issue. Please contact the seller have m/b exchange first.

This is after I told them I already replaced the motherboard with a brand new one and also after I told them other people have this issue + linked them this thread. 

At this point, ASRock support seems to have casted this issued aside without acknowledging it even exists.  If they don't acknowledge the issue then it is doubtful it'll be fixed.
