Poor multicore performance (not CPU Throttling) (HP ZBook 15u G6 Mobile Workstation )

HP Recommended
HP ZBook 15u G6
Microsoft Windows 10 (64-bit)

Hello all,


Sorry to bother you about this.


My new workstation is very good over all, but one thing it does that annoys me slightly is how it lowers the CPU speed when all cores are in use. This doesn't affect me too often, but could in the future.


To resolve, so far I have:


Ensured it's plugged into mains power

Made adjustments to the BIOS

Created a High Performance profile in Windows 10

Un-installed and re-installed potential software that is limiting the speed.


I notice that when there is a very light load, the CPU hovers around 4GHz. When a load is applied (3D rendering), it goes down to around 2GHz. It seems it's being a little too cautious about temps, which do not exceed 50-55C at peak.


When I'm doing graphics intensive tasks, I can hear the GPU fan spin up, but I've never heard the main CPU fan do the same - I'd have no problem with the noise if it's giving me the performance I'd like. I wouldn't expect the 4.6GHz Boost clock all the time, and I don't think I've ever seen it, but it would be nice to at least have 4GHz at least.


Look forward to any comments you might have.
