4 cores and 7 threads

[AKriv1]

My pc can see only 7 threads. I checked the BIOS and everything was fine there.

But the Device Manager shows all 8 threads

I would still update the bios, and reset to the defaults. If the problem persists, contact the system\motherboard manufacturer.

And, what operating system are you running?

It is possible to disable logical processors in Windows. Are you sure you haven't accidentally done so?

Note the following mini-tutorial: http://solidlystated.com/software/how-to-disable-a-cpu-core/ How to turn off a CPU core or limit cores on dual-core/multi-core computers.

Hope this helps,
