    Quoted from Pin_Guy:

    Your chip is a standard 32k x 8 (256k) RAM chip.

    Do I need to solder a socket to put this chip in or can I just solder the chip onto the board?

    Quoted from PinballManiac40:

    Install a socket in case it fails. It will be an easier swap for anyone, if needed. Some games, like South Park already have an IC socket on the board from the factory. What game are you wanting to install one? Is it a Rottendog board?

    It's a rotten dog board in a mars God of War
