Changing dedicated memory from 64 MB to 124 MB???

Heyyy so I'm wanting to play the Sims 3 on my laptop and all of my specs match up, just my memory card says it has 64 MB of dedicated memory when I need a minimum of 124 MB, but I know I have 1071 MB of total available graphics memory. I heard you can change your dedicated memory through BIOS, but I honestly have no idea how to do so or if it's safe for someone like me (basically technology UN-savvy) to do so. If you could tell me if it's kinda foolproof or if it's easy or anything, that would be amazing. Thank you so much in advance.
