I recently bought a Core 2 Duo processor and was trying to install it in my XFX 680i motherboard. I'm used to AMD procs where all you do is line up the pins and drop it in. The locking arms on those drops down quite easily. No need for any force at all really. However, when installing my Core 2 Duo it seems in order for the locking arm to go down it needs quite a bit of pressure. I'm not sure if this is due to the fact it doesn't have pins or not. I hate to force anything when it comes to installing hardware. Am I supposed to put that much force on it?
