I downloaded some work units only to have the system fall back to smaller number of cores due to exceeding the 50% realm of usable RAM from my machine. Never have I had a problem except in Atlas@home and Lattice@home use more then 50% which in my case is my system has 32 Gig Ram available. So 16 Gig of RAM is pretty rough and tough system use. I adjusted the usability of % to 90% and I still got a shut down of usability to only 4 work units, those are serious work units. I also wanted to let anyone know that each work unit has nearly 100 meg per work unit being downloaded for each work unit. So if your paying for bandwidth and data used, watch out.! I reset my Lattice @Home project and left it lie there whimpering as it won't be getting me to help anytime soon.
