    How to get Windows 10 PRO to see both CPU


    I have an older Dell T5500 workstation I am using as my desktop. I am running Windows 10 Pro 64-bit Version 10.0.18362 Build 18362 and have 2 Intel Xeon x5675 (@ 3.07GHz) installed. When I go to the device manager it shows 12 cores but Task Manager only shows 6 cores and 6 logical processors. How do I get Windows 10 to use both CPU?How to get Windows 10 PRO to see both CPU-pc.jpg

    As you probably know, Windows 10 Pro X64 supports two physical CPU sockets.

    A random thought: when I was working in industry, my desktop workstations were from Dell. The IT department's default for a new PC was to turn off hyperthreading in the PC's BIOS. Maximum compatibility, I guess.

    Is hyperthreading activated in your machines's BIOS settings?

    I shall check

    That did it! I went to the BIOS and hyperthreading was not activated. It now shows both CPU with 12 cores and 24 logical processors. Thanks!

    I'm mildly surprised, but I'm glad to help.
