I have a couple of p4 1gb machines. I want to hook them up to screamernet for a make shift renderfarm. My question is how can I tell what is the max capacity of ram I can put in? I have 3 slots and planned on buying 512’s fr each slot but someone said I could mess things up by puttin to high of a capacity of ram in there. Is this true? ANy advice appreciated.
