    i7 2600k Hyper-threading problem


      Hi everyone,


      I'm having problems with Hyper-threading in my new build.


      My setup consists of:


      Windows 7 Ultimate SP1 OS


      ASUS Maximus IV GENE-Z motherboard

      i7 2600K 3,4 ghz CPU

      8GB Corsair Vengeance Low Profile DDR3 1600 mhz CL9 RAM (2x4GB Kit)

      OCZ Vertex 3 120 GB SSD

      Corsair HX850 PSU



      When I have HT enabled I get random reboots and crashes and it seems like one of the threads is not working properly.


      For example if I run HyperPI 1M one of the threads/cores only calculates 16K so the 1M calculation fails. I don't have this problem when I turn off HT.


      I ran Prime 95 with HT disabled for six hours straight with no errors.


      With HT enabled I'd usually find that the computer rebooted during the night as I left it running while I slept.


      Everything is stock, no OC whatsoever. Vcore was around 1.248v, VCCSA/IO 1,05.


      Does anyone have any ideas what could be wrong with my CPU? Could it be damaged?
