Is this a pin in the cpu's LGA?
This is the LGA
If it is in that place. use the system and as long as it works, you should be fine. It is rare for a pin to get bent in the LGA, but sometimes they look bent and are not. They are also not fun to unbent.
Please note that the memory controller and some of the PCI-E slots are also fed from the LGA. so if those work and the system is stable, count your self as luck. Some pins are extra grounds that may not be required.
I have never seen software to see what pins do what because even the OS does not know this. It just knows the cpu talks X86.
