I'd be very surprised if the memory situation didn't get better. When I built this Skylake PC, I initially got a set of 4 dimm modules for 16GB (4x4) because the store had run out of 2x8. My PC wouldn't post with all four DIMMs in. I took 2 out, leaving 8 gigs in total. I ran a mem test just for laughs getting massive errors. I gave up. However, the store got more 2x8 sooner than I expected, and they switched my 4x4 to one of those (that's what we agreed when I bought the parts). Using that 2x8 set, I installed both. The PC didn't post. I only left one in, it finally posted, and mem test was good. I updated the bios, installed the other DIMM as well, and got good mem test result. That's with Intel's nth generation of i cores and chipsets. If the situation with Ryzen mem doesn't get better, then there's something seriously wrong, but for now troubles are only normal, as funny as it sounds.
