I ordered a render farm from our IT Group, thinking that they could figure out them selve what to buy.
But then they returned with the question, "how much ram do you want in the machines?" And I have no idea.
I thought that the machines should only have a good CPU and a Gigabit net. Am I wrong, do i need a lot of ram to be able to set up a renderfarm for C4D?
Each computer or blade needs RAM. How much depends on the type of rendering you do. 16GB should be sufficient for most purposes.
But before you make the leap ... what version of Cinema do you have? Keep in mind that Maxon eliminated NET Render with R15. They added Team Render in its place, but many users aren't happy with it as it doesn't have the same management functions as NET.
