So I want to update my BIOS to see if my CPU really is just a dual core... but I've never done it before and I'm worried about fuc*ing up my only PC. So is the BIOS update utility that comes with the mobo any good? And is it really worth updating BIOS for that?
Also here is the asus BIOS download page; should I download the latest or an of the earlier updates if I do decide to go through with it.
You can always go back to an older bios if there are problems. I have never heard about an update removing any options from a bios. The newer chipsets (870 880 890) don't natively support core unlocking so the motherboard manafacturers have added there own.
