In Vegas Pro where you select the amount of RAM to use (under Video preferences) I was wondering if this amount of RAM you select is used only while Vegas is open or does it still allocate use of that amount of RAM from your system when Vegas is closed thereby cheating your system of available RAM?

The reason I ask is I also use Photoshop CS5 and it too has a preference to select the amount of RAM used so I would hate to eat up RAM needed by the system when neither of the programs are open and being used.

My new system specs in case it factors into the answer to my question:

Windows 7 64 bit machine
XPS 8300 Intel Core i7-2600 processor(8MB Cache, 3.4GHz)
12GB DDR3 SDRAM at 1333MHZ, 2x4GB/2x2GB
AMD Radeon HD 6770 Graphics card


Thanks in advance,

It is used only when Vegas is open.

Thank You Edward, I appreciate your help.

Nice system, Tim, sounds very fast!

It is used only when Vegas is open.

Edward, based on the specs of the system what amount of RAM would you suggest I set Vegas at?

Thanks Jeff, it seems fast so far..

I always keep the number fairly small. When rendering, many rendering issues can be resolved by keeping the number small. Really the only time it needs to be bigger is if you're doing RAM preview renders - then the higher the number the longer the amount of time you can preview render.

Got it, Thanks again Edward!
