Well like the document advises, a page file 1.5x the RAM should be enough, especially in a system like yours where avalable RAM is not an issue. It's the recommended total, so all page files added up/total virtual memory, no matter how you spread them/it out.
What I've done now is make a set page file on a separate drive in a dedicated partition, like I mentioned before, and set it to system managed for C:. The document seems to indicate Windows will prefer the set-size one on the other disk, since that doesn't contain boot/system files and sees less traffic as a result. That way Win always has 2 options to work with and the chance of running out of space is essentialy non-existent, while allowing it to use the less-used disk at that moment for the paging.
Think that'll work out nicely. It even worked perfectly without the bit on C:, but maybe now that it has another option things will be even smoother.
