i have been in BIOS and set to" sync all cores"
i have also been in msconfig at set to 4 cores,
but still in cpu-z and core temp its says 2x cores and 4 threads
any help here
You have half of your CPU disabled.
This problem can usually be fixed by going into msconfig, click on the Boot tab - Advanced Options and then making sure that Number of processors: is
not checked. There is an internet myth that setting this to 4 will speed up your boot times or something silly like that. Your CPU supports hyperthreading which means your 4 core CPU can process 8 threads of information at a time. If this is set to only 4, only half of your CPU is being utilized.
Once you uncheck this box reboot and see what RealTemp, the Task Manager and CPU-Z say. The APIC ID box in RealTemp shows 0 1 2 3. That means hyper-threading is enabled which is good but only the first two cores of your CPU are active. It should be showing 0 1 2 3 4 5 6 7
It's an internet myth and like other internet myths, if it gets repeated enough it seems to become true. I have no idea when the msconfig idea got started.
On some motherboards, if you put 4 in that box, this was a "trick" to disable hyper threading. Some gamers didn't like hyper threading when it was first introduced so this trick disabled it. Depending on how Windows and your bios get along; this trick will either disable the last 4 threads or every other thread. If it disables every other thread, that would be good for this purpose because you would end up with 4 cores and 4 threads. On your motherboard, it disables the last 4 threads so you end up with only 2 cores and 4 threads or exactly half of what you paid for.
Leaving that box unchecked is usually best. Then when Windows boots up, it is able to find all your threads.
Post some pics to show your new and improved CPU. It really makes me wonder how many people around the world are using only half of their CPU because of this.
CPU-Z will show you how many cores and threads you have. If the APIC ID box in RealTemp shows 0 2 4 6 then that means msconfig is disabling every other thread and you have 4 cores 4 threads.
