" Fantastic. So I need a 2 Gb RAM to working 100% with Poser6. And if my motherboard dont allow more than 1 Gb RAM Im pissed" erm no. you can reach 2GB right now. the Limit mentioned is Phyisical RAM + Virtual = Windows Total Ram. if your MB has 1GB and you set your Virtual to 1GB you'll have 2GB of RAM for a program.
