Recently I’ve had some issues or I’ve noticed that not all the cores are getting full use on my system, one core was high usage where the others were more or less idle. I found a fix which can help share the work across all the cores on the CPU. This does require changing your registry, so if you break anything, dont be blaming me!
- Go to Regedit
- Select Edit > Find… and find this key: ” 0cc5b647-c1df-4637-891a-dec35c318583 ”
- Within this key, there is a value called: ” ValueMax ” This value represents the % number of cores the system will park
- Change the value of ” ValueMax” to 0 so that, it matches ” ValueMin ”
- You will have to find the key a few times and repeat the process for each time it is found – the number of instances will depend on the number of power profiles in your system. To do this go back up to Edit > Find Next.
- Do a full shutdown and power-off and cold-re-start.
The Result
Better load balancing across all you CPU cores – no spiking – in Windows 7 Task Manager
