RAM Cache Help

I plan on setting up a 16GB RAM cache but have a few questions:

-What software is recommended? I plan at this point to use the Asus RamCache software.

-How do I protect from write loss in the event of a power failure? I only want to cache reads, not writes. Is this possible?

-Should I disable Windows Superfetch and leave everything up to the RAM cachce?

Any other "best practices"? Thanks.
