Haven’t tried with no CPUs yet, what’s flummoxing me is the fact that no combination of what I choose gets anything. Is it possible a bad board could have damaged both CPUs?

Make sure you're not excessively tightening the bolts of the HSF or waterblock. Cooling solutions that are too tightly mounted can result in all sorts of weird problems from dead memory channels to failure to POST.
These were both common failure points on X99.

And it was way past the return period. Reseated everything, tried RAM in every slot, moved things around, etc. Nothing works. Then the epiphany. I had to reset the BIOS. That took care of the issue. Since you didn't mention doing that, I'm throwing this out there.
