i need some some help i just upgraded my cpu form a fx 4170 to a fx 6300 and windows is saying it a 4 core cpu and not a 6 core i done all the updates from windows and bios too and still showing as a 4 core and prime 95 is saying its a 4 core and cpuz too saying 4 cores
go to task manager and see how many threads are available, should be 6. i would say its windows system information not showng things properly. Otherwise, go into bios and makes sure all cores are enabled, even try hard reset the motherboard bios.
^ +1 I would go into the BIOS and see If all the cores are enabled. If not, Enable them.
