In case anyone is wondering why a ramdisk may speed up some tasks , compare your own benchmarked disk drive which stores the page file ( the extended virtual memory space of solid state ram memory ) with that of page file performance in ram memory space

1GB is only maybe 20% of allocated page file space but Windows will tend to use the fastest storage device first - so is reasonable to expect that even such a small capacity ramdisk will be well used 

The other advantage is for those using SSD's which are reputed to suffer " wear " - a ram drive for the page file should reduce this - and for those with electro-magnetic drives , should be evidenced by less clicking noise during task processing  

However for any particular usage resource system memory requirements there should be enough excess free memory space  to create a ramdisk without compromising other ram intensive sub-systems like graphics shared system memory or else performance or quality will be degraded

In the end maybe only observably useful for some computers and usage 

As usual , if in doubt , don't.
