System Requirements for base game and each pack says 4 GB RAM and 18 GB worth of memory, so it is 35 total with base game and all the packs, soon to be 36. So 35 times 18 is 630 GB worth of memory and 140 GB of RAM is the recommended requirement amounts which I highly recommend with save files and pictures and mods/CC use. Fun mini research project looking it up actually with EA Desktop which honestly runs so much better than Origin.
