    3930k only using 6 threads?

    ches rowe

      I have a 3930k , it's supposed to have 6-cores and 12 threads, but in CPUID and task manager it says my processor only has 6 sixs and 6 threads?

      Are these programs lying , or do i need to activate the other 6 threads somewhere?x

          Hi Ches Rowe,


          You are right; the i7-3930k has the Intel® Hyper-Threading Technology (Intel® HT Technology) that delivers two processing threads per physical core.

          So in order to check if this technology is enabled:


          In Microsoft* Windows*7, XP Home or XP Professional, Vista there are two easy ways to determine if Hyper-Threading Technology (HT Technology) is on without having to reboot to enter the BIOS setup.


          1. Task Manager: Hit CTRL-ALT-DELETE and click on the Performance tab. You will have CPU Usage History windows. If you have a single core with HT Technology, you will see two thread windows. In this case since you have an Intel® Core™ i7-3930K that has six cores and twelve threads, you will see twelve windows.


          1. Device Manager: Open Device Manager and click on Processors. You will see two processors listed. For Windows* 7, go to Control Panel, Hardware and Sound, Device and Printers, Device Manager, scroll down to Processors, and expand it to see how may threads are showing (Dual Core Processors with Hyper-Threading will see four processors).


          Performance will vary depending on the specific hardware and software you use.
