You can not use all your 8 gig-ram , you will leave windows with no memory to work

 

windows uses 2 gig + the memory for max + bitmaps, graphic interface , etc

Does it use 3000 mb or we can increase that aswell???

first as what francosd said the OS need his own memory space to use it for the other applications, secondly this is not the memory that the vray will use only this is special kind of needs for vray :

Dynamic memory limit - the total RAM limit for the dynamic raycasters. Note that this limit is divided between the number of rendering threads. If you specify 400 MB total limit, for example, and you have a dual processor machine with multithreading enabled, then each rendering thread will use 200 MB for its dynamic raycaster. If this limit is too low, and geometry needs to be loaded and unloaded very often, this may turn out to be slower than rendering in single-threaded mode.
