Question Active Processor Cores option not detecting all cores

[sunehildeep2019]

My motherboard is zebronics z55 and I've a i7 870 processor. The option in Bioa of Active Processor Cores shows only 3 options which are "All, 1, 2"
Which means that its only detecting 2 of the cores but it has 4 cores and I get low Fps in games. How do I fix it?

Do you try update the BIOS? If no, and update the BIOS.
