Achieving High skin details for characters with less system ram

In this short tutorial i will be sharing a break down of how i made super high skin details for my character's i am selling, sculpting them in 322 000 million polys with a very small machine - 12GB ram - dual core 2 processor & NVIDIA quadro FX 2700M graphics card. For this you will only need Zbrush, and please note its not a modeling tutorial but a break down for the skin details. If many requests pop up i might make a step by step video tutorial.
