I know that Win98 is supposed to have a problem with extra large amounts of RAM. I've also heard people say that setting your swap file (I call it a swap file for 9x and a page file for 2K... weird, huh?) to RAM x 2.5 is the way to make it stable. Then there was the time when you were supposed to set it to 2.5 x RAM to optimize performance.
I've got a full gig of RAM in my Win98SE machine, and it's been running beautifully for most of a year. The only reason I even need a swap file is because Adaptec says you can't create a CD without enough space in the swap file for a CD. Strange that.

Anywho... general questions...
Who's running how much memory on 9x and getting away with it?
AND
What are the secrets to making 9x run smoothly with much RAM?
