You can set it to 0, and V-Ray will use as much ram as is available. Or you can cap it at something like 10,000mb if you want it to not eat all your ram.

As a side note, for slightly faster renders you can also turn off "Low Thread Priority" in your Global switches. This will throw everything your computers got (CPU) at the rendering, but you wont be able to do much else with the machine while its rendering like that.
