Not sure what the problem is.
The problem is probably the BIOS not reporting the correct/full memory. Seems common on ACERs.
Before hitting <Enter> on the CD boot screen, hit the <Tab> key - it wil give you the kernel options for the installer. Go to the end of the line and add the following (note the space character at the beginning), and hit <Enter>. After the install completes all your memory should be recognised correctly (not just the 1024m)
As an aside, there is very ittle to be gained installing Fedora 20 at this time - F21 has been released, and you should probably install that. Fedora has a fast release cycle, and you really need to staay current.
