[SOLVED] Why task manager shows that my CPU has 2 cores while it has 4?

[Wittusus]

My CPU is Athlon II X4 870k with 4 cores and 4 threads according to CPU-Z and everything else, but task manager is showing 2 cores 4 threads. Why?

Someone else ran into this issue recently. Because it's actually 4 cores inside of 2 modules windows doesn't show the cores properly. cpuz is correct as always.
