You are right. The memory should be able to run at DDR4-3200 speed. However, this is not 3200 mhz because it is double data rate memory. It would actually be 1600 mhz. Based on the tests you have shown the memory is running at approx DDR4-2666 speed or 1331 mhz. 

 

I believe the problem is that you have installed "Ballistix" gaming or performance memory and it is souped up to run at low CL latency of 16. Stock latency would be 21 or 22. You need to use standard OEM memory on HP laptops even workstation and gaming models. Pretty sure HP did not install that Ballistix memory from the factory. What kind of benchmarks do you get on the originally installed memory?
