Hi Blikbrein,

I do not really understand your question.
1 Gb RAM / 3.8 Gb chip PC?
Maybe you mean 3.8 Ghz CPU. In that case I can say that our largest project - Help Defeat Cancer - runs quite well in 1 GB of RAM but does not leave much room for a second project. The other projects can run at least 2 work units simultaneously in 1 GB if you have 2 cores, but 2 of our second-largest project (HPF2) might slow down a little from time to time due to memory contention. The smaller projects can all run at full speed with a multi-core CPU. In general, a dual-core CPU is the best way to speed up a computer's output. You just have to keep track of the individual project sizes and perhaps avoid the projects with the largest memory requirements.
