You can raise that to 4.

Just use ether the old or new 4gb patch.
From my Previous post= The dude must have thought you were talking about the pc patch. The pc has a memory limit of 2GB of RAM.
Are we talking about the same thing? Because the PC has a 2GB RAM limit and the only way to raise it is with third-party software. It has not been patched to raise the limit, it's still at 2GB RAM and Bethesda has not stated any reason as to why they put a limit on it and has no intention on rising it.
The Dude must had thought you were talking about the PC patch. No way would you get a response like that if he knew you were talking about the PS3. A memory limit on a PS3?? You can't adjust the memory on a PS3.
Check the email that you sent to them. How did you structure your words?
