Well I finally ordered a new motherboard and cpu combo for my aging machine. It was getting to the point where larger idv bundles were dying in mid process due to lack of ram. Nothing special (on a tight budget), but I have an AMD 2.0ghz with 1.5gb ram on way. That is a lot more processing power than my aging Duron 850mhz with 512mb ram! Hopefully I will be able to enjoy IDV without it locking up halfway through a bundle!! Thanks. On 2/19/07, Tom Whittaker <tomw@xxxxxxxxxxxxx> wrote:

Yes, you are running in a "limited" setup, so don't expect to be able to do much with images, in particular. And things will possibly run a bit slow. > One thing I did notice, even while IDV or the GUI was not doing > anything, the ram down in the bottom left was constantly climbing > eventually hitting the ceiling.

And what version of the IDV are you using?

Obviously, you need to get enough CPU -- but 2GHz should be enough. I would get at least 2GB of memory.....
