[ANSWERED]Strange behaviour in a ramdisk

During a another test with  a latest version of Winreducer, all functions seems are good.
But when i try to configure a program for a memory management, AsRock's X Fast Ram, it was inable to function normally. More specific, if i set a virtual disk for a ram over 4Gb, (my machine have 8Gb) the system failure.
But if i try in a standard installation of Windows 8.1, all function without problem.I can set a virtual disk of X Fast Ram until a 6,5 Gb. Why happens this misterious behaviour? This is a link for the wccf file compiled
