When I run a Graphics Benchmark Test on my PC's the CPU Clock Speed is not at Maximum, why?
Steps to Resolve
1. If you are running the Graphics Benchmark Test om a laptop first check the Power Settings and make sure that the laptop is set to run on maximum power. This should lift any restrictions there might limit the CPU from running at full power.
2. If the above did not solve the issue on your laptop or if you have a desktop computer then also check the BIOS settings on the PC and make sure that the CPU is set to run at maximum power.
