I did a test here and no problem to load 5 Vic4 with hair, cloth and body textures with no scale. Try to change the settings for your Spool Texture. The idea there in the Preferences / Imaging, Scratch Disk is tell Carrara from where to begin to use the disk as memory. With 200Mb Carrara will only begin to use the disk after get this value in RAM. Dont use low or high values, try to stay about 200.
