rhophius, I have an i7 2600, GTX580 and 12GB RAM, WIN7-64. When you speak of the 4BG RAM fix are you referring to this Skyrim4GB download? How is it used? I did not download it because it said it was source code. I don't have a compliler and no experience with source code. Also, the description makes it seem dodgy. Can you explain this fix in detail? Thanks.
