FX8300 OC 4.2ghz Software Bug?

Hello out there boyz!

Currently im running an old FX8300 Unlocked CPU OC to 4.2ghz with water-cooling of course . I've noticed maybe a software bug with AMD Radeon Software , CPUZ and the Windows Task Manager . is this a software bug or my CPU works on 4 cores while i have 8? I didn't find any setting into my bios for cpu cores or something..

AMD Radeon Software reads my CPU as 4 Cores .
CPUZ reads 8 cores 8 threads

Task Manager reads 4 cores and 8 logical 

Mobo : ASUS M5A97 LE R2.0

Screenshots are attached .

Re: FX8300 OC 4.2ghz Software Bug?

See if this previous MS Forum thread helps explain your question: Why does Task Manger shows half of the cores? - Microsoft Community  also FX-8370 – Win Task Manager shows 4 p. cores and 8 l. cores 

The FX8350 has 4 modules of 2 cores each. Windows defines the 4 Modules as "Cores" and the 2 cores in each Module as "Logical Cores".

This lawsuit against AMD in 2016 concerning the same question about how many actual cores are in the FX 8xxx series may help clear somethings up: AMD sued: Number of Bulldozer cores in its chips is a lie, allegedly • The Register
