HOW TO DISABLE HYPER-THREADING

Below is an example on how to disable Hyper threading. This interface might be different on windows 10 but gives you an idea how to disable it.

Step1:  Save any work, and reboot one of the controllers. 


Step 2: While your PC is rebooting, enter the BIOS setup screen. You can do this by hitting either the ESC, F1, F2, F8, F10, F12, or Delete key(depends what is shows on the reboot screen) on your keyboard.
while the system is loading.




Look on the initial boot screen for an indication of this. It will either say BIOS Setup or simply Setup next to a listing of which key to hit. If Windows shows up too fast for you to see which key to hit, check your owner's manual for which key to enter the BIOS setup screen.

Step 3: Locate the Hyper-Threading or Hyperthreading control. It's usually under a sub-menu for one of the following key words: CPU, Processor, Performance, Advanced BIOS, CPU Feature, Theaker, etc.



Step 4: The control itself should be called CPU Hyper-Threading, Hyper-Threading Function, Hyper-Threading Technology, or Intel (R) Hyper-Threading Technology. It should be set to Enabled by default.



Step 5: Move the cursor over the word Enabled, hit Enter, then move the cursor up or down to select Disabled. Hit escape a couple times to get to the exit screen, type Yes or Y to let the system exit while saving changes.



Congratulations, your system now has Hyperthreading disabled, and will only handle as many threads as your system has physical cores. (i.e., if you're using a quad-core CPU, four threads can be computed at once).
