To Nukeboy :- I only have 156meg of ram !!! ,and my swap file limits are not set, this is the default (Let windows manage swap file) However I followed the DAZ tech tip and installed "Cacheman" using 'recover memory' every 10 minutes. Memory can also be recovered manually in a crunch by right clicking the toolbar. The part baffling me is that big renders wont start with a high memory figure? (over 100 meg) and when this happens I lower the figure by opening and closing Outlook and Coreldraw to suck the ram down, technically I would think the more ram the better, but this machine seems very happy to render on an empty tank. The computer lease runs out early next year and I'm already planning its replacement with a 17" monitor priority on top of the wish, list and yes! screw up your faces! I will buy another Hewlett Packard as this baby has never missed a beat in 4 years, just become out-dated. Tommy.
