    Core i7 not using all cores/HT?


      Dell Optiplex 980 with Core i7 860. Fresh install of Window 7 x64. Device manager show 8 processors, CPU-Z shows 4 cores with 8 threads. When I watch the processor graph in Task Manager I only see activity on processor 1, 3, 5 and 7. HyperThreading is turned on in the BIOS but the machine does not appear to be using them. I'll see very small blips when doing something very processor intensive, but for the most part they are at 0%.


      How do I utilize these extra "processors" ?
