I am talking about something like this: http://www.superspeed.com/servers/ramdisk.php
RamDisk Plus has a most unique feature. Our patent pending technology can access memory beyond the limitation imposed by a Windows 32-bit operating system! In other words, RamDisk Plus 10 can use "unmanaged" Windows' memory e.g. above 4GB. It can also use the stubbornly inaccessable memory between 3.2GB and 4GB
Sounds great and works indeed. I would like to buy some of those but server licenses cost 350 US$. Is there a cheaper similar solution around somewhere?
