More ram usage for projects

My workstation has 6GB of RAM. Platinum 7 only uses 500MB RAM and 600 MB paging. Any way to set it to use 85% RAM and 15% paging. 800MB RAM and 300MB paging to improve performance. My 2 hour project took 1 hour 35 minutes to encode.

actually a 2 hour project on 1:35 is pretty good. I don't believe playing with the ram will help you. VMS is kinda "set" in its way I believe. The things I know that can help are of course the obvious - latest dual or quad core processor, motherboard and ram. Judging from your name you are already familiar with hard drives. I know having the operating program and source files on one drive and destination file on another drive can significantly reduce time. Of course one must consider the source and final product as well in rendering time. A simple straight cut video is certainly faster verses a heavily composited and modified video - or for those brave ones - HD. Since VMS doesnt take advantage of the latest video cards - a decent video card is all you need. If you do a search for Johnny Royfrano (he is a Vegas expert) he has a suggested system that is really fast on his web site.

What leads you to believe that using more memory will help? Have you watched a render with Task Manager to see the performance? If you are near 100% CPU, and you aren't seeing many page faults (use the "Select Columns" menu from the "View" drop-down in Task Manager to see counters like page faults or virtual memory size) then I would say that memory usage isn't the problem. From what I have seen, and from what I have heard other people describe, the Virtual Memory size of a typical render is usually about 300-500 mb, so you should have plenty of memory unless there is something unusual about your project (like lots of hi-res stills).

AMD dual 265 Opterons (four 1.8 GHz cores)
PCI-X SCSI RAID controller with 512MB cache
Tyan Thunder K8W server board
ATI x800XT AGP card
6GB of RAM.

Upgrading to dual 280s, 8GB RAM, X1950 Pro PCI-e x16, Tyan Thunder K8WE board.

All high res stills. JPGs are 4-6MB each being encoded down to standard size. The four 265 cores are at 65%. No difference having the pictures on my RAID 10 array encoding to RAID 0 array.
