ERAM is an Opensource RAM Disk that uses page/non-paged/external RAM. You can use it for storing temp files, browser cache, etc. to speed up the programs that use those files.
ERAM has a limit currently of 4GB.
Run the 32 or 64-Bit exe (you might have to run the Installer with Driver Signature Enforcement Disabled for it to install without any errors) and follow the instructions.
After installing, the RAM Disk will be available as the R: or Z: drive with a size of 1 GB (for 32-bit OSes) and 4 GB (for 64-bit OSes) which can be changed as you see fit by running eram.cpl by pressing Win + R.
