What to do with a ton of extra memory?

"Let Windows manage the memory. It does a much better job than you can, even if you understand how it works, which you probably don't.
A RAMDISK is almost always a poor use of memory.
Disabling the pagefile will more often than not impair performance."

Try putting portable Firefox on a ramdisk and enjoy a dramatic speed increase. Dataram is free and saves its contents to hard disk when you shut down the computer (and optionally at regular intervals).

"These days the ""slowness"" of a PC are most likely caused by your harddisk. You should try to use your ram to tackle this weakness.

Create a big ram disk partition (~3GB), set your frequently used programs to use that partition as temporary drive. You'll be amazed by how fast your programs will become."

"Open all your favorite application on window startup. then you can reach them from taskbar.
Play many games at cone. Never close them. Just use ALT+TAB when you get bored.

Don't disable windows page file because when you are saving from disk, you are adding more traffic to the ram bandwidth. That would create a bottleneck on the bandwidth when you are using the programs which matter more."
