How much virtual memory should I set it to?

Microsoft recommends that you set virtual memory to be no less than 1.5 times and no more than 3 times the amount of RAM on your computer. For power PC owners (like most UE/UC users), you likely have at least 2GB of RAM so your virtual memory can be set up to 6,144 MB (6 GB).
