Windows 7: Canīt see all my CPUs/trheads on dual Xeon configuration

Canīt see all my CPUs/trheads on dual Xeon configuration


I have a strange problem on a HP z600 with dual Quadcore Xeon @2,93 Ghz with HT, OS is Windows 7 Ultimate x64.

CPU-z can see correctly two cpus with 4 cores but with only 4 threads.

I checked BIOS settings and I enabled HT and multi cpu support, than with CPU-z i can see only 1 processor with 4 cores and 8 threads.....

On msconfig>boot>advanced options>Number of processor the scroll-down show from 1 to 8 as maximum.

Testing with cinebench or frybench only 8 cores are working instead of 16.....

Where is the problem?

Need KVM to switch dual monitors to 2 cpus
Please recommend a simple(manual?) KVM to switch dual monitors between 2 different cpus. Prefer USB for KB and wireless mouse and VGA for monitors, using Win7 (although DVI is ok). I don't need to switch audio.
