View Full Version : 12 GB of memory + vista 64bit

Hi I have question with regards to the way Windows vista 64bit handles memory. I plan to upgrade my pc to an Core i7 platform and plan run 2 sets of 6 GB tri channel memory units (12 GB total). My main use of the computer is graphics / photography / and gaming. If I had Photoshop CS4 (32bit) and Photoshop Lightroom 2 (32bit) since Adobe has yet to release any of their programs in 64bit. My question is how will vista 64bit handle these 32bit apps memory allocations? For example will vista allow both programs to use up to the max 4 GB each that 32bit program can recognize? Or will all of these 32bit applications be force to share the first 4 GB of memory on the system?

Memory break down:

Photoshop CS4 : 4gb used memory
Photoshop Lightroom 2 : 4gb used memory

Leaving Windows vista with 4gb of memory left

Well, both Photoshop cs4 and Lightroom 2 come in native 64bit flavors, so they'll both use as much ram as is available. I am currently running Lightroom 64bit on Vista 64 with 8gbs of ram installed and it hardly ever, unless rendering a huge batch of previews/files, uses more than 2gbs of ram. Photoshop on the other hand when doing large (10+) 12 megapixel image panoramic stiches will use up ram like it's going out of style well over 6gbs etc . However, what you need in the end for real speed is a fast, separate, physical scratch disk. So I would make sure to Buy a nice speedy HD (640aaks is good) just for scratch.
