Its impossible to unlock intel cpus as they made it in the die, so its all internal and was locked during manufactoring process.
To unlock AMD cpus u need some sort of conductive material, mainly to join the bridges together. The usual method works, but needs a steady hand.
If your planning on overclocking, maybe try changing the voltages, n making sure the divider for the pci r set correctly, otherwise u might get artifacts from your video cards, n sometimes could result to damage of parts.
