Nice one. Looks like a good chip
Play some more with memory settings for other benchmarks. It will help in Spi32, XTU or even Cinebench. At least use dual channel
Kingston is using Hynix so you can probably set something like 3000 15-15-15 at ~1.35V or maybe 3200 15-15-15 or 16-16-16 1.35-1.45V. Can take a look at my Kingston DDR4 tests, should be some settings there if you wish to try ( in sig is link ).
