Same here but you got me thinking. A bit of Googling came up with this freeware RAMdisk which might do the job. http://memory.dataram.com/products-and-services/software/ramdisk? It's freeware up to 4GB and you can get more for a small price. I haven't tried it and my Win 7 system has much less memory than yours, so I doubt it would be much use to me unless I upgrade.
