Here’s a clearer version of your situation:
I own a Dell Precision 7510 laptop running an Intel Core i7-6820HQ processor, which is a quad-core chip at 2.7GHz. Recently, I encountered performance issues when using CPU-intensive programs. In the Task Manager, under the Performance tab, it displays only two cores being utilized, not the four available. This discrepancy is confusing. I also have HWinFO installed to monitor system settings, which confirms there are four logical CPUs. However, my monitors show only two of the four cores being used. I’m wondering why this happens and how to resolve it so I can fully leverage all four cores.
This situation came up after a major hardware problem around Christmas, which forced me to reformat my drive and reinstall Windows. I’m trying to understand if this is connected to that past issue.
It appears HT plus certain cores are turned off in the BIOS. Your HWinfo lists 4 logical cores, whereas your CPU should display 8 if correct. It seems the hardware monitoring tools always show the standard core arrangement regardless of BIOS adjustments, so they should reflect 8 threads even with some disabled in the BIOS settings.
Thanks for the feedback. The box in MSCONFIG wasn’t checked, and I reviewed the BIOS settings—there was an option to enable cores with radio buttons, which was set to 2. I also confirmed all options were selected. It seems hyperthreading wasn’t turned on either. A recent BIOS update might have caused these changes. Appreciate the assistance, everyone! Matt
