^ Nice to hear the confirmation message from a 3930K owner. :)

 

Second that, i really dont think i have. The only thing i have changed is moved my memory to the proper frequency, even if i have overlooked some setting i nudged (which would have been reverted to default when i updated the bios anyway so i cannot be that) i don't know of any setting that would cause this effect without manually changing the active cores setting.

Rgr. What did Intel say;

 

I will be taking it to the repair center of the place i bought it from they said they can fix/replace it there on monday (australia.)

 

I dont really have a phone for a (probably lengthy) call to intel, sorry. but i will report back once they look at it.

I recently got myself a i7 3930k and an Asus Rampage IV Extreme mobo, i have discovered that if i have hyper threading enabled it will only enable 3 physical cores and thus have 6 threads. However if i disable hyper threading it will enable 6 physical cores and have 6 threads, all of this is supported by evidence form windows task manager, CPUZ and OCCT.

 

I have left all other cpu setting default, this has been happening since i got it and the only thing that seems to change it is the hyper threading switch.

 

If i cannot have hyper threading that's fair enough i am not going to go ape over it but it says i can have hyper threading so i want the choice. I just dont understand why this would happen, any help would be greatly appreciated guys.

 

NOTE: i will attach two screenshots from CPUZ, one with HT turned on and thus 3 physical cores and 6 threads, and one with HT turned off and thus with 6 physical cores and 6 threads.

 

I have exactly the same problem, my rampage extream has been sent back and so has my 3930k and they can't find anything wrong with them how did you resolve please please help. am loosing the plot
