Have you checked BIOS settings that no cores have been disabled?

In MSConfig it shouldn't show 4 cores. In the BOOT tab, Advanced button it should have the "Number of processors" box unchecked with a grayed out '1' showing in the list box.

Is your BIOS up-to-date? that would be at least rev 5007 for a 3500X processor.

Bios is July this year, seems recent enough. Open up your case, Do a hardware Bios reset. Locate and do the following.

look at the motherboard Overview, you see number 11 which is the clear Cmos switch, if you aren't sure what to do, scroll down a bit it will tell you.

Was this Windows installation freshly installed with this mainboard and CPU, or, perhaps a previously used installation with an earlier mainboard/CPU?

actually my windows didnt get a fresh install after replacing it because my friend said my old windows was already compatible. my old specs coincidentally had 4 cores and 4 threads too so that might be the problem

When you change the motherboard you need to do a fresh windows install. Your friend is not helping you.

Do what I said in MSConfig earlier: clear the checkbox beside Number of Processors. That commonly happens with a change of processor in a window's installation. Also be sure to install the AMD chipset drivers.

So, that should fix the problem with not using all your cores but you're quite likely going to have more problems if you don't do a fresh install of Windows. If it doesn't fix it then you will absolutely have to fresh install to do so.

Agree, all Bios and settings aside. Reinstall Windows. It does happen that it doesn't recognize the new cores when upgrading.
