Missing Cores

[PixelGeek]

What's the opposite of hyper threading?

 

TL;DR: My 4 core i7-2600 is only using 2 of its cores. help.

 

    My dad just bought a used Dell Optiplex 990. The sales man claimed that it was "very fast". Every where i look, the computer gives me conflicting answers. This computer is for 3D modeling, so not having all cores present is not an option. I just did a BIOS update, that did nothing. In the BIOS, all 4 cores aren't showing up (Picture 1). Yet, it acknowledges that it has 4 cores (Picture 2). HWinfo says that it has 4 cores, but the little CPU activity window only shown two cores working (Picture 3).

Download CPU Z and see what that says.

 

You can also show individual core usage by right clicking on the CPU graph in the task manager and choosing logic processors.
