3x the ram? Where do you get that from? I've never made one that large. 1x the ram is plenty for most people with modern systems, and if you are using it at all, you should consider getting more memory at the current price of memory.
The page file is additive, so 1x gives you twice as much virtual memory.
With only a 32G "drive", I think it's important to at least limit the max size of the page file.
