I have just got a AMD sempron to see if it will unlock the second core making it dual core. How can I unlock the second core?

Might be an option in the BIOS. Whats the mobo? If its an Asrock, it looks like there's an option called Asrock UCC (dont know which mobos have this option tho) in the BIOS. Enable it

Look for core unlocker in the BIOS. Set it to enable. And change the setting under that to Auto. Save settings / reboot. See if it works. If it doesnt work that CPU probably doesnt support unlocking

I tried it out and the machine just went black. Wouldn't boot into windows at all. Took the CMOS battery out to get it sorted.

Looks like it may work, if you enable it then disable it then enable it again. Dont forget (if you pull the battery), you'll have to reconfigure the BIOS settings. You may also have to put the CPU voltage up in the BIOS (dont ask me how) to make it stable. If the screen goes black again, you may not be able to unlock the other core

Had to set the time up again in windows after the PC rebooted.

Yup you'll have to set it in the BIOS first. It'll probably be wrong if you reboot. What BIOS is on it?? Its up to 0901

Don't do it in windows. If it supports ez flash update it in the BIOS with a usb flash drive. After you unzip the file

Try changing CPU core activation to manual, then select on under this
