I would add that the new MBs, mine included, have somewhat changed their meaning when they refer to ‘Turbo’ and the like. To get 3.2 MHz from my machine I had to select a high performance option in my bios. The same is true for your DDR memory. Go to tomshardware.com and search around if you haven’t already.
You should definitely install ‘Latency Mon’ and cpuz_64 on your machine to see what you are getting. For example, typically, if you install your DDR4 ram and do NOT tell your bios to run it in high performance mode, your 32 MHz ram will run at 24 MHz or thereabouts. Definitely not what you paid for. The surprising thing is that with all the stops pulled out, my machine is virtually stone quiet. Also, FWIW, the latest Win10 1903 OS update (18362.418) is the best update so far.
