Hello Brian, the Intel® Core i7-4510U is a dual core processor.
There are two ways to limit the amount of cores being used by the Intel® processor:
- The BIOS settings were modified to use only one core from the processor. If you have updated the BIOS, try resetting the values back to default, save, and check again.
- In the Windows* utility msconfig; if you navigate to Boot, Advanced Options, the box Number of processors should be unchecked; otherwise it may limit the amount of cores.
If you still see the Intel® processor as a single core I suggest contacting the system manufacturer for further assistance. It is possible that there is a special configuration in your system that limits the amount of cores.
Thank you for your response. You are right. Those settings you mention, I did modify them. I installed MyDell and it corrected the misinformation. as it turns out my system is a 2 core system, and now windows 8.1 recognizes it. weird how that happens. Now I'm testing the CPU performance with Need for Speed to see if it corrects the latency problems that I was having. hopefully it will be back to normal. As far as the BIOS goes, I haven't check in to see if the CPU options are there from the previous BIOS version, before I updated it. I'll use your suggestion and see if it works.
