Re: Ram Usage

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!!

I'll see if I can answer.

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.

This is not normal.

You are looking at the far left of the 3 numbers?  What had  you done
up until then?  And what version of the IDV are you using?  And how
long does it take before hitting the ceiling?

I would say that memory is more of an issue that CPU for you.
Obviously, you need to get enough CPU -- but 2GHz should be enough.  I
would get at least 2GB of memory.....

Hope that helps.
