add temporary RAM disk then use it as cache of SSD

On my PC, over 90% of CPU power is not used. And there are unused memory. So basically I don't need your software. How about utilize the unused memory and CPU power to construct RAM drive temporary then use it as cache memory of SSD? I think your way of "Boost" is somewhat passive but this way is active. I know such kind of software but it cost more than $30. The RAM drive is the point. It should not be "static" bacause it affect application. It does not need to use it as regular disk.
