HP Z600
Microsoft Windows 10 (64-bit)

I am using Hp z600, has 2 processor xeon x5675, I recently realized wich only one cpu is working. Since a couple of months I upgrade to W10x64 (on W7 everyting was working  fine).

 

Right now:

 

- BIOS recognize 2 cpu and all the theads are enabled

- DeviceManager show 24 processors

- Windows task manager show only 1 soket, 6 cores

- Graphic software I'm using show only 6 cores

 

I already try to:

 

- unmount and switch the cpu

- change the motherboard and update the BIOS to the last version

 

When I changed the motherboard w10 just ask me to restart from a previus point, so I don't have format again.

 

Can be really Windows?

Next step I'll try to format again. Thank you in advance if someone have a good idea!
