    Windows 10 only shows 1 core on 4 core CPU


    I've had my old Windows 7 AutoCAD machine lying around for a really long time in storage, and I just thought I'd drag it out and clean it up. I erased the hard drives which still had Windows 7 and some of my old school stuff on them and installed Windows 10, only to be greeted with an extraordinarily slow experience. at first I thought it was just because it was an old q6600, but I later found out Windows was only using a single core.


    I checked in BIOS, all of the cores are enabled. I also reinstalled Windows 7 although I've lost my activation key, so I can't activate it which sucks and I have confirmed that in Windows 7 it does indeed show four cores. I know for a fact I've used Windows 10 on q6600 CPUs, because one of the machines at my job has the same CPU and is currently running Windows 10 with all four of its cores enabled.


    I found a couple potential fixes, but none of them seem to work at all, windows simply refuses to see any more than one core. Is this because I haven't activated Windows yet? I made sure to run all updates after I installed Windows 10, but once I saw that it was only using one core, I decided to hold off on activation until I knew if it could be fixed or not


    Q6600, 8 gigs of RAM, 100 gig SSD, 1Tb HDD, dual Quadro FX 4800 and an EVGA 680i motherboard

  3. core unparking

    I have a I5 7600 4 core cpu everything in the system is show 4 cores but there parked, I have the software for unparking them but when I use that it only shows 2 cores and that they are unparked but in the task window in performance it show all 4 cores
    and that they are parked? so I'm not sure which is right and which is wrong since the program to unpark the cores is only showing 2 cores and not seeing the other 2 cores, but in the registry which is where it's looking all 4 cores are listed there. So my
    main question then is there a place in the registry that you can change the cores to unpark them?

    Windows 10 only shows 1 core on 4 core CPU

    ONLY showing using 1 core out of 4 core processor

    Open up task manager, select performance tab, select cpu.......then look at the bottom right of window. There you will find the info on your cpu......sockets, cores, logical processors and your cache. This is mine....a single processor with 4 cores that has hyper-threading which gives me 8 logical processors.
